Do you think it’s normal for your
dentist to check your prostate?”
I ask the new hygienist. “Be -
cause Dr Plaque checks mine every
time I come in.”
At this point, somewhat alarmed,
the hygienist glances at the last entry
in my chart, under which, while unat-
tended, I have written, “prostate nor-
mal.” After I explain my little joke to
the slightly creeped-out young woman,
all my appointments go pretty much
the following way.
“You haven’t had X-rays for a
while so we should do them.”
“Why?”
“Well, Dr Plaque likes to have
them done periodically to check on
things.”
“Well, then Dr Plaque can pay for
them.” I don’t think the dentist likes
me.
Imagine, doing a periodic X-ray to
check on things. This has always been
frowned upon in our profession. How-
ever, we are now on the crest of a brave
new scanning wave. Patients can pay
privately for almost any scan imagi-
nable. Then with the scans and reports
in hand they come to us for advice.
The problem is that nobody really
knows what to do with the results.
Randomized controlled trials that
investigate the impact of routine diag-
nostic imaging on mortality and mor-
bidity are scarce. So what does one do
with an otherwise healthy 50-year-old
man who pays privately for a coro-
nary CT that shows calcifications? Do
you order a stress test, exercise MIBI,
angiogram, or just monitor and en cour-
age risk-factor modification (which is
what was prescribed prior to the scan
anyways)? How about tiny renal or
lung lesions? What about small cere-
bral ischemic changes? The list goes
on. Private companies are happy to do
the scans, but what is the next step?
Patients are signing up for virtual col -
onoscopies, ultrasounds, CTs, PET
scans, carotid dopplers, and more in
ever-increasing numbers.
Let’s not forget magnetic resonance
imaging (MRI). Oh, how I hate those
three letters. It doesn’t seem to matter
what the patient’s problem is, eventu-
ally they always come to the conclu-
sion (based on the expert advice of
editorials
Invasion of the body scannerstheir lawyer, spouse, parents, physio,
massage therapist, barista, or garden-
er) that they need an MRI just in case
something is being missed. This hap-
pens despite my explanation that an
MRI won’t aid in the diagnosis of their
ingrown toenail or make their obesity-
related back pain go away. I am con-
sidering purchasing a big magnet to
glide over people while I make a
humming noise. I will then give them
a stick drawing of the appropriate
injured area and bill them for a dis-
count MRI.
Technological advances are often
a good thing, but some rational judg-
ment must be applied. There is still
an art to practising medicine, an art
that can be intriguing, satisfying, and
alluring. I’m calling for the use of
good old common sense. A good ques-
tion to ask is, “Is the management of
this patient likely to change depend-
ing on the outcome of this test?” If
not, don’t do it. If your patients remain
dissatisfied, send them to my newly
opened discount MRI clinic.

W e are approaching the end
of an era at our community
hospital. As you read this
line, you may be expecting a lament
on the death of the full-service family
physician. The family doctor who has
an office practice, hospital privileges,
does house calls, does palliative care,
delivers babies, and perhaps also does
ER work. The dinosaur that has previ-
ously been described in these pages,
and whose imminent demise has been
much lamented. This would be a rea-
sonable thought.
It may also be reasonable to expect
an essay on the demise of the commu-
nity hospital. I expect that this may
happen soon in the new era of “pro-
gram management.” The new buzz-
words in our health authority seem to
be carving our once unified hospital
into separate silos of health care deliv-
ery. Our interdependent departments
such as obstetrics, pediatrics, anesthe-
sia, and surgery are being managed
and directed by individuals who are
not on site full-time because they have
too much on their plates and have to
manage and direct multiple hospital
sites and programs.
But, alas no. I am going on about
the imminent loss of an indispensible
person at our hospital, our medical
staff secretary who for approximately
the past 17 years has been doing her
job with amazing dedication. Unfor-
tunately, she is retiring and her posi-
tion is not going to be filled.
I must be getting old. I find myself
reflecting more and more about how
things used to be. I am becoming one
of the When we generation. You know
who you are. You start sentences with
When we, such as, “When we started
at this hospital…” It is true.
When I started at my hospital 20
years ago, I applied for hospital privi-
leges through the medical staff secre-
tary. It was the medical staff secretary
who organized my pager for me, as
well as the multiple replacements I
have needed over the years. She
reminded me that my annual dues
were overdue, as was my annual reap-
plication for hospital privileges. The
medical staff secretary took minutes
at our medical staff meetings (and
many other committee meetings); she
coordinated our on-call schedules and
notified others of the changes that we
seemed to make so frequently. The
medical staff secretary updated our
hospital’s physician directory, an
indispensible tool for us and our office
staff. She was the “go to” person at
our hospital when one had a question
or a problem. She coordinated weekly
education sessions for physicians. Our
medical staff secretary managed our
medical staff bank accounts and
administered the scholarships our
hospital medical staff gives to worthy
medical students each year.
Her job description has been chang -
ed by the hospital administration. She
editorials
The end of an erais no longer supposed to be doing the
things she has done for the medical
staff for the last 17 years. She has out-
lasted every other secretary in the hos-
pital. She has gone above and beyond
on many occasions, quietly and effi-
ciently. She is due to retire shortly.
The glue that holds our hospital’s
medical staff together is about to be
dissolved.
By the time we realize what we
have lost, it will be too late. From one
dinosaur to another: Have a well-
deserved retirement, Marcy. You have
certainly earned it. We will all miss
you. It won’t be same around here any
more. —DBC

A s long ago as 1999, the Sup -
reme Court of Canada decid-
ed in the case of Terry Gris-
mer to instruct all motor vehicle
licensing authorities to make fitness-
to-drive decisions on the basis of
functional capacity, not simply by
diagnosis, as had been done previous-
ly. Mr Grismer was the operator of a
mining truck and wanted to continue
his employment after a stroke pro-
duced a homonymous hemianopsia
that eliminated most of his left-side
peripheral vision in both eyes. Al -
though, sadly, Mr Grismer died while
the human rights legal challenge was
making its way through subsequent
levels of court, his estate pursued the
matter to this conclusion.
In our province, the Office of
the Superintendent of Motor Vehicles
(OSMV) then began a consultation
process and planned for the publica-
tion of a new BC Guide in Determin-ing Fitness to Drive to replace the
1997 edition. After a long consulta-
tion period, in which many doctors
volunteered their time, the new edi-
tion was published online in July
2010. It was always the intention to
also publish a condensed and user-
friendly guide for physicians, as the
full edition was aimed more toward
the needs of regulators. This task has
now been delayed until at least 2011,
with no announced plan for medical
editing and consultation.
At the time of this writing, the
BCMA does not know when and how
the new Guide will be implemented.
The first reading of Bill 14–The Motor
Vehicle Amendment Act, 2010, in part
21, provided for government to set out
by regulation the medical conditions
or functional impairments that oblige
a physician or other health profes-
sional to report.
Doctors can feel uncomfortable
balancing the mobility needs of a
patient against the potential risk to
public and patient safety when con-
sidering whether and what to report.
In my experience, a lot of the risk is
related to the driver’s level of insight.
A “safe enough driver” is aware of
any cognitive limitations and has the
judgment and willingness to adapt his
or her driving to these limitations. The
most dangerous situations are those in
which the driver denies or minimizes
the reduction in his or her functional
ca pacity and makes no accommoda-
tion for it.
When facing such complex deci-
sions it has been very helpful for BC
physicians to know they could contact
a medical consultant employed by the
OSMV. The OSMV used to have two
part-time medical consultants on staff.
For the past 10 years, Dr John Mc -
Cracken provided this valuable serv-
ice; however, his contract was not to
be renewed. The BCMA and the Col-
lege of Physicians and Surgeons of
BC have jointly written to the OSMV
to highlight this concern and request a
meeting. With the demographics of an
aging population and more crowded
roadways this is a time that we need
more medical consultation available
—not less.
Meanwhile, DriveABLE is the test
that the OSMV has contracted with
the BC Automobile Association to
provide objective information to assist
in decision making when there is
a concern about cognitive function.
The OSMV is also proposing to use
SIMARD-MD, a brief pencil-and-
paper test, to assist health care pro -
viders in rapid screening of patients.
This approach has been used in a lim-
ited way in Alberta. We await the start
of a proposed pilot study in BC.
Functional capacity is much more
than the score on a test—without a
mechanism for meaningful and trust-
ed consultation we run the risk of even
more rigidity in fitness to drive deter-
minations than existed when only
diagnosis was used.
The BCMA’s Board of Directors
was kept regularly informed during
the preparation of the OSMV’s cur-
rent Guide, but the BCMA was never
advised of plans to discontinue the
role of medical consultant or the use
of medical appeals. We need to find a
way to address this social and medical
issue together and not lose many years
of medical “corporate memory” and a
spirit of collaboration, as we move
ahead.

Re: Medicalmarijuana
W hile Health Canada has
delegated responsibility to
physicians to recommend
the use of cannabis for access to their
legal program, it has clearly abdicated
its responsibility to educate doctors to
ensure their medical opinion is more
informed than that of Dr Vroom [Med-
ical marijuana. BCMJ 2010;52:329].
As a result, Dr Vroom is not alone
is his lack of knowledge about the
medical use of cannabis. During our
many years working and conducting
research at both the British Columbia
Compassion Club Society and the
Van couver Island Compassion So ci-
ety, we have heard the other side of
doctor-patient dynamic that Dr Vroom
describes.
Many patients report having an
extremely difficult time obtaining
support from their physicians for the
use of this medicine, or even dis-
cussing this legitimate health option.
This deeply affects the doctor-patient
relationship, causing patients unnec-
essary stress and creating an atmos-
phere of shame and distrust. Sadly,
many patients find themselves in the
role of having to educate their doctors.
Cannabis is a legal therapy option
officially sanctioned by the federal
government. It is not a physician’s role
to decide what is or isn’t a medicine,
but rather to discuss the suitability of
treatment options on a case-by-case
basis. In a previous editorial, Dr Vroom
stated, “I am not afraid to keep an open
mind about remedies I know nothing
about, but I research their scientific
evidence.”1 Dr Vroom seems to be mak-
ing an exception for medical cannabis.
Thousands of peer-reviewed sci-
entific studies have been published on
the use of cannabis to treat many dif-
ferent conditions and symptoms—as

both symptom relief for conditions
like chronic pain and to slow disease
progression. For starters, we suggest
that Dr Vroom might check out the
Canadians for Safe Access (CSA)
research page (http://safeaccess.ca/

upcoming accredited course by the
Canadian Consortium for the Investi-
gation of Cannabinoids (www.ccic

Dr Vroom respondsMs Capler and Mr Lucas are correct
about my lack of knowledge of mari-
juana pharmacology. Their recom-
mended web site has, unfortunately,
not educated me any further.
The whole crux of my editorial
was to acknowledge that I have no
knowledge about all of the actions of
the 60-plus cannabinoids contained in
a joint, nor of their potency or con-
centration. That makes endorsing, let
alone prescribing, a substance such as
this problematic for me. I pointed out
that the only legal way to access mar-
ijuana is by the recognized indications
contained in the Health Canada Form
B1 and palliative situations. Ms Capler
and Mr Lucas maintain that it is not
for physicians to decide what is or
isn’t medicine. Maybe so, but there
are many medicines that I won’t pre-
scribe. And that is my right. Just
because Health Canada has created
“medical marijuana” as an escape
from advocacy group pressure doesn’t
mean that I have to accept their prob-
lem as now being mine.
Marijuana has an excellent reputa-
tion for being a recreational drug. I am
sure that, some day, research will lead
us to completely understand all of its
actions. Perhaps we may even see it
legitimized for recreational use. In
the meantime call it “experimental
marijuana,” “research marijuana,” or
“palliative marijuana”—anything but
“medical marijuana.”

ied and the appropriate dosage is
unclear.
“Many regulatory authorities
(Colleges) have considered these
facts. Some have stated clearly that
physicians should not support an
application for the medical use of
marijuana, while others have cho-
sen to simply remind their mem-
bers of the importance of evidence-
based medicine and the lack of
evidence about the benefits and
risks of this substance.
“However, patients who believe
that marijuana is effective for treat-
ing certain symptoms from which
they suffer can apply to Health
Canada for authorization to pos-
sess and use marijuana under the
Marijuana Medical Access Regu-
lations (the Regulations). Those
Regulations require the applicant

tions, one of which is the appli-
cant’s and the other a Medical Dec-
laration signed by the applicant’s
medical practitioner.”

Incorporating high-quality evidence
into clinical decision making re -
quires systematic searching, apprais-
ing, and synthesizing of the literature.
Performing these complex and time-
consuming tasks on a regular basis
is beyond reasonable expectations
for busy physicians, so using existing
sources of evidence-based informa-
tion, particularly systematic reviews,
is helpful. Unlike traditional narrative
reviews that are generally written by a
few authors who subjectively select
literature to comment on a broad topic,
systematic reviews tend to be pro-
duced by a team that endeavors to
search the literature on a narrow clin-
ical question in an unbiased and repro-
ducible manner and analyze the search
results according to explicit criteria.
Two initiatives of note that produce
carefully synthesized and appraised
systematic reviews are Clinical Evi-dence from BMJ Publishing Group
and the Cochrane Collaboration. Both
tend to focus on the benefits and harms
of clinical interventions.
Clinical Evidence, created in 1999,
summarizes systematic reviews, RCTs,
and observational studies, and states
college library
Best evidence: The tip of the informationiceberg
the current view on what is known and
unknown about specific aspects of
disease management. Conveniently,
patient leaflets on general topics sup-
plement the more precisely focused
systematic reviews. Clinical Evidenceis both a stand-alone publication as
well as a component of BMJ Point ofCare. The Cochrane Collaboration, a
distinct and independent organization,
has been producing the CochraneDatabase of Systematic Reviews since
1993. The Collaboration is not-for-
profit, funded by agencies such as
universities, charities, and personal
donations. Like Clinical Evidence,
Cochrane reviews tend to focus on the
risks and benefits of therapeutic inter-
ventions. Both of these resources are
available for free to all College mem-
bers at www.cpsbc.ca/library.
In addition the College Library
offers workshops on identifying and
effectively searching high-quality
medi cal evidence, and we are also
happy to arrange one-on-one learning
sessions with College members.

In the first part of this two-parttheme issue, we discussed the etiology, diagnosis, and nonoper-ative treatment of osteoarthritis
(OA). While the majority of patients,particularly those with small joint OA,respond to nonoperative treatment,surgical treatment is required in anincreasing proportion of patients withlarge joint OA. With the ongoing im -provements in outcomes and with theadvent of very predictable and durablesurgical technique, younger patientswith OA are requesting the pain reliefand the improved quality of lifeafforded by these operations.
Hips and knees continue to be the
joints most commonly affected and
requiring surgical intervention. His-
torically, hip and knee joint replace-
ment were reserved for older patients,
and it was not uncommon to hear
patients complaining that they were
denied surgery because they were “too
young.” In the past, with the limited
durability of joint replacement, that
was a reasonable strategy to protect
patients from failed joint replacement
down the road. Today, however, tech-
niques for first-time joint replacement
have improved so significantly that
we can offer joint replacements with
predictable longevity, with fewer
complications, and with less severe
failures. Moreover, revision surgical
techniques have also improved to the
point where even when joint replace-
ments fail, they can be predictably
reconstructed in the majority of
patients.
In the articles that follow, we begin
with an overview by Dr McCormack,
who describes the role of arthroscopy
in early OA of the knee. Because knee
OA often presents with isolated dis-
ease in one of the three compartments
of the knee, we continue with Dr
Schweigel’s discussion of partial knee
replacement. Dr Williams, Dr Garbuz,
and I then consider total knee replace-
ment. We finish with Dr Burnett’s
article about hip replacement and
resurfacing.
With the increasing success of hip
and knee replacement, demand will
continue to increase. It is my hope that
the articles in this two-part theme
issue will put the topic of hip and knee
osteoarthritis in perspective. I am
extremely grateful for the contribu-
tions of the various authors who have
done an excellent job of summarizing
this vast topic in a clear and concise
manner.

ABSTRACT: Degenerative joint dis-
ease is a common cause of knee
symptoms and disability. The indica-
tion to proceed to surgery is usually
the failure of standard nonsurgical
treatments. Despite the success of
joint replacement surgery, many cli-
nicians choose to avoid this large,
complex surgery if a minimally inva-
sive ambulatory procedure can allow
a patient to improve function and
quality of life. This has led to the fre-
quent use of arthroscopy to treat
degenerative joints, especially knee
joints. While a “scope” does qualify
as minimally invasive, it is still im -
portant to consider the ratio of risks
to benefits and the efficacy of arthro-
scopic debridement for degenera-
tive joint disease of the knee.
The impact of osteoarthritison the health care system issignificant and continues togrow as our population ages.
As there is no cure for degenerativejoint disease (DJD), medical interven-tions have focused on symptom con-trol. Unfortunately, none of the non-operative measures are universallysuccessful and some have significantrisks. A minimally invasive day-careprocedure that improves patient func-tion and delays more extensive recon-struction is appealing. Arthroscopy isthe most commonly performed ortho -paedic procedure, one often associat-ed with knee ligament reconstructionand treatment of meniscal tears. Inaddition, some estimates suggest thatover 500 000 arthrosco pies are per-formed in North America each yearfor the treatment of degenerative jointdisease.1 Recent studies have ques-tioned the role of this procedure in thetreatment of osteoarthritis, and thereis a general consensus that it has beenoverused in the past. The goal of thisarticle is to address the role of arthro-scopic surgery in patients who havedegenerative joint disease in the knee.
Proposed benefitsIt has been proposed that arthroscopic
lavage (wash out) of the knee joint can
improve patient status by washing out
inflammatory cytokines, cartilage frag-
ments, and other debris from the joint.
Formal joint debridement has also
been reported to improve patient
status by smoothing off unstable flaps
of articular cartilage and possibly
improving the weight distribution of
the remaining articular cartilage.2
On the one hand, if there is an
unstable meniscal fragment that is
causing mechanical symptoms, such
as locking, pain with sudden turns, or
sharp intermittent pain, an arthrosco -
py can address that component of the
patient’s symptoms by trimming the
unstable fragment. On the other hand,
it is difficult to quantify the benefit of
arthroscopic repair of the arthritic
knee given the inability during arthro -
scopy to actually perform biological
resurfacing in the face of diffuse
degenerative changes and the ex -
tremely variable course of DJD.
Recent studiesMost of the orthopaedic studies re -
garding the role of arthroscopy in the
treatment of DJD are of low quality
and suffer from the same short com-
ings seen in many other areas of med-
icine: variable selection criteria, incon-
sistent outcome measures, different
surgical techniques, and publication

attention because patients were ran-
domized to one of three arms: arthro-
scopic lavage, arthroscopic debride-
ment, or sham operation. The patients
were assessed by a blinded independ-
ent assessor and the key finding was
that there was no significant differ-
ence in pain or function between the
sham operation and either of the
arthroscopic surgery groups. As inter-
esting as the results were, the design
of the trial also captured a lot of atten-
tion. The placebo effect of surgery was
neutralized by giving the patients in
the sham operation an anaesthetic and
creating the standard arthroscopic
portals, without performing any sur-
gery inside the knee.
The Moseley study created a furor
among orthopaedic arthroscopists.
Many criticized the design of the
study and the fact that all subjects
were males (in a female-dominated
disease) and all came from a Veterans
Affairs hospital (equivalent to work-
ers’ compensation patients). There
were concerns that the patients had
more severe disease than average and
that the authors used a nonvalidated
outcome measure. Nevertheless, sev-
eral societies, including the American
Rheum a tological Association, came
out with position statements that
arthroscopy did not have a role in the
treatment of osteoarthritis.
This controversy spawned further
trials in a number of centres, and re -
cently a prospective randomized clin-
ical trial from the University of West-
ern Ontario was published, again in
the New England Journal of Medi-cine.6 This Canadian trial by Kirkley
and colleagues randomized patients to
optimal medical treatment or optimal
medical treatment plus arthroscopic
debridement. The researchers defined
the grade of arthritis more precisely
and ensured that limb malalignment
was not significant. The patients in
both groups had similar age, BMI, and
length of follow-up. Importantly, the
researchers excluded patients with
significant meniscal tears that were
causing mechanical symptoms. The
primary outcome was the validated,
disease-specific WOMAC score.7 The
bottom line is that the trial addressed
most of the criticisms of the Moseley
trial. Interestingly, at 2 years follow-
up, the WOMAC scores were not sta-
tistically different (P = .22) and with
an absolute difference of less than 1%
that did not meet the threshold of a
clinically significant difference.
Significance of findingsWhat do these findings mean to the
clinician? Degenerative joint disease
of the knee ( ) is common and
family physicians often decide to order
an MRI to assess the joint. Since the
same degenerative process affecting
the articular cartilage also affects the
menisci, it is not surprising that most
of these patients also have a degener-
ative tear of the meniscus ( ).
Unfortunately, the patient and physi-
cian frequently focus on the MRI
results and forget clinical correlation.
When there are significant degenera-
tive changes most of the symptoms
are related to the underlying degener-
ation. Asymptomatic meniscal tears
are very common in this clinical situ-
ation and men iscal resection does not
address the main pain generators. As
the Moseley and Kirkley trials show,
when there is significant degenera-
tion, arthroscopic debridement inclu -
ding resection of degenerative menis-
cal tears ( ) does not lead to
improvement in pa tient outcomes, and
may in fact lead to more rapid deteri-
oration.
The one caveat to this is that the
presence of significant mechanical
symptoms (locking, significant catch-
ing, or instability secondary to a torn
meniscus or loose body) is different
from isolated joint line pain. These

bias. Through the 1980s and 1990s a
variety of case reviews reported a rea-
sonable rate of improvement with
simple lavage or joint debridement in
knees affected by osteoarthritis. The
success rates ranged from 40% to
75%.2 As might be expected, the ben-
efits of simple lavage were, at best,
transient and one small prospective
randomized trial found that arthro-
scopic lavage was no more effective
than closed needle lavage of the joint.3
The evidence supporting arthro-
sco pic debridement was somewhat
better, but improvement was frequent-
ly of short duration and studies show -
ed that orthopaedic surgeons were
actually poor at predicting which
patients would improve.4 In 2002 this
technique came under close scrutiny
when the results of a prospective ran-
domized trial by Moseley and col-
leagues was published in the NewEngland Journal of Medicine.5 This
trial captured a tremendous amount of

mechanical problems are more pre-
dictably improved with arthroscopic
resection of the torn meniscus or loose
body. However, it is important to
remember that there may well be
residual symptoms, secondary to the
underlying DJD. The role of the pri-
mary care physician is to educate
patients that significant degenerative
changes are not helped by an arthro-
scopic “clean out.”
A second caveat is that occasion-
ally there is an indication for a diag-
nostic arthroscopy in a degenerative
joint, to better define the extent of
damage or to determine the role of
other procedures such as realignment
osteotomies or unicompartmental
arth roplasty. This may also apply to
patients whose symptom severity is
out of keeping with the radiographic
evidence. The patient can have changes
that appear mild on plain radiographs
but when examined arthroscopically
prove to be more severe with large
focal defects in articular cartilage.
Even if arthroscopic debridement
offers a small benefit, this needs to be
balanc ed against the risks of the pro-
cedure. Complications, including deep
venous thrombosis and pulmonary
embolism, are not to be underestimat-
ed and have ranged in some series
from 7% to 31%, with a higher preva-
lence in older patients.8
ConclusionsRecent high-quality trials suggest that
in the absence of mechanical symp-
toms, arthroscopic debridement of the
knee has a very limited role to play
when managing significant degenera-
tive joint disease.

ABSTRACT: Partial knee replace-
ments have come into and out of
favor over the past 60 years. There
has been renewed interest in partial
knee replacements in the armamen-
tarium for arthritic knees due to
increasingly good results. Partial
knee replacements include the uni-
condylar knee replacement and the
patellofemoral arthroplasty. These
partial knee replacements are indicat -
ed for specific, isolated arthritic por-
tions of the knee joint—specifically
the medial, lateral, or patellofemoral
portion of the joint. In carefully
selected patients outcomes are com-
parable to the results of total knee
replacements. Patient selection and
meticulous surgical technique are
likely the key to a good result in a par-
tial knee replacement.
Partial knee replacementsare a form of knee arthro-plasty that doesn’t replacethe entire knee (the femoral
condyles, tibial plateau, and patella).These surgical interventions includethe patellofemoral arthroplasty andthe more common unicondylar kneearthroplasty. Both procedures havebeen available since the 1950s andmay be options for patients who haveosteoarthritis in one compartment ofthe knee, do not have specific con-traindications for these more conser-vative procedures, and who havefailed to benefit from nonoperativemanagement of their osteoarthritis.
Unicondylar kneearthroplastyIn the past, unicondylar knee replace-
ments fell out of favor primarily be -
cause of the surgical technique of the
time, which made conversion to a full
knee replacement difficult. However,
with the advent of minimally invasive
approaches for unicondylar knee
replacement, there has been renewed
interest in this procedure over the past
decade.
A unicondylar knee replacement
( ) consists of a metal compo-Figure 1
nent that goes on the femoral condyle,
and another component that goes on
the tibial side. The tibial component
can be metal-backed with a fixed-
bearing or mobile-bearing polyethyl-
ene bearing surface, or it can be an all-
polyethylene fixed-bearing cemented
component. There is no evidence that
one approach is better than another.
The rationale for considering a
unicondylar knee arthroplasty is that
it is a more conservative operation
with faster recovery, less resection of
bone, conservation of the cruciate lig-
aments, and potentially better func-
tion. In addition, conversion to a total
knee replacement down the road is
simple using modern techniques, with
outcomes similar to a primary knee
replacement. When appropriate, par-
tial knee arthroplasty can be thought
of as a time-buying operation.
In addition, a unicondylar knee
replacement is an alternative to other
invasive procedures such as a high
tibial osteotomy or a total knee
replacement.
Partial knee replacementThe last decade has seen renewed interest in unicondylar kneearthroplasty and patellafemoral arthroplasty for patients with osteoarthritis affecting one compartment of the knee.

Patient selectionCareful patient selection is needed to
get the best possible results. This re -
quires a thorough history and physical
examination.
The history should include specif-
ic questions about the knee to deter-
mine whether there was a gradual
onset of pain or whether there was a
specific incident (i.e., trauma) that
caused the problem. This is particu-
larly important because anterior cru-
ciate ligament deficiency is a con-
traindication for a unicondylar knee
replacement. When considering a uni-
condylar knee replacement, the loca-
tion of the pain is very important. It
must be localized to only one com-
partment of the knee. For a medial uni-
condylar knee replacement, the pain
has to be medial and the patient has to
be able to point to the medial side of
the knee as the site of the pain. For a
lateral unicondylar knee replacement,
which is much less common as the
results are less predictable than a
medial unicondylar knee replacement,
the pain has to be lateral. For either a
lateral or medial unicondylar knee
replacement, the presence of substan-
tial patellofemoral pain is a con-
traindication. In addition, the pain has
to be of sufficient magnitude and to
interfere with activities of daily living
to warrant surgical intervention. It is
important to ensure that all reasonable
attempts at medical management have
been exhausted before considering
any surgical procedure.
IndicationsKozinn and Scott have outlined several
classic indications and contraindica-
tions for unicondylar knee replace-
ment.1 Indications include the diagno-
sis of unicondylar osteoarthritis or
osteonecrosis in either the medial or
lateral compartment of the knee. Ini-
tially, Kozinn and Scott stipulated that
patient age had to be greater than 60
years and weight had to be less than
82 kg. There had to be minimal pain at
rest and low demand of activity. The
ideal range of motion was an arc of
flexion of 90 degrees with a contrac-
ture of less than 5 degrees. The angu-
lar deformity had to be less than 15
degrees and be passively correctible
to neutral at the time of operation.
Specific contraindications to a uni-
condylar knee arthroplasty identified
by Kozinn and Scott included the
diagnosis of an inflammatory arthri-
tis, age younger than 60 years, high
patient activity level, pain at rest (which
may indicate an inflammatory com-
ponent), and patellofemoral pain or
exposed bone in the patellofemoral or
opposite compartment at the time of
the surgery. Asymptomatic chondro-
malacia in the patellofemoral joint
was not necessarily a contraindication.
More recently, some of these indi-
cations have been expanded. Various
authors have reported good results in
patients younger than 60 years2 and in
obese patients with BMIs over 30.3
Generally it is felt that both of the
cruciate ligaments have to be intact to
perform a unicondylar knee arthro-
plasty. Again however, studies have
suggested that a medial compartment
unicondylar arthroplasty is possible
in an ACL-deficient knee in certain

circumstances;4 still, most surgeons
will not perform a unicondylar knee
re placement on a patient with a histo-
ry of torn ACL, and the presence of
a torn ACL should be considered a
contraindication to a unicondylar knee
replacement.
In summary, in addition to well-
localized pain with no patellofemoral
involvement, the indications for a uni-
condylar knee replacement include
the following:
• Range of motion of no less than
110 degrees with no more than a 5-
degree flexion deformity.
• A correctable varus on valgus defor-
mity of no more than 5 degrees of var -
us or 15 degrees of valgus, with the
correctability of the deformity to be
determined on physical examination.
• An intact anterior cruciate ligament.
• Osteoarthritis localized to either the
lateral or medial compartment, keep-
ing in mind that the vast majority of
unicondylar knee replacements are
medial.
• For some fixed-bearing tibial compo-
nent designs, a weight limit of 114 kg.
Based on the above, it is clear that
not every patient with knee osteo -
arthritis is a candidate for a unicondy-
lar knee replacement, and the final
decision is up to the orthopaedic sur-
geon. Typically, only 10% to 20% of
patients undergoing knee replacement
are candidates for unicondylar knee
arthroplasty.
ResultsIt is difficult to sort out the results for
unicondylar knee arthroplasty, as
there are different types of unicondy-
lar knee arthroplasties. Additionally,
it is difficult to distinguish between
medial side versus lateral side proce-
dures with respect to outcomes. Fur-
thermore, one has to compare the
results of a unicondylar knee replace-
ment with other options such as a high
tibial osteotomy and a standard total
knee replacement. Again, various au -
thors have reported varying degrees
of success with unicondylar knee
arthroplasty. Recently authors have
reported 96% survival of the implant
at a 10-year follow-up and excellent
or good outcome in 92% of patients.5
Most recently Newman and col-
leagues6 compared unicondylar knee
replacement with total knee replace-
ment in a prospective randomized
control trial. This report stated that the
15-year survivorship for a unicondy-
lar knee replacement was close to 90%
compared with 80% for a total knee
replacement. Additionally, the report
stated that the unicondylar knee
replacements had more “excellent”
results and a better range of motion
compared with the total knee replace-
ment. Registry data, however, such as
the Swedish Knee Replacement Reg-
istry, have shown a higher reoperation
rate for unicondylar knee replace-
ment, with the main reason for revi-
sion being progression of the arthritis.
The results for revision of a unicondy -
lar knee replacement to a full knee
replacement are similar to the results
for a primary total knee re placement,
and even though unicon dylar knee
replacements may not last as long, the
outcome of revision is better than that
of a revision of total knee replacement.

ComplicationsThe complications after a unicondylar
knee replacement are similar to a total
knee replacement. These complica-
tions include inadequate pain relief,
deep venous thrombosis in 1% to 5%
of patients, infection in less than 1%
of patients, and unexplained pain
about the knee.
Late complications include loos-
ening of a component, subsidence of
the component, degeneration of the
other compartment resulting in pain,
infection, polyethylene wear, and pos-
sible dislocation of the polyethylene
component in a mobile-bearing knee
replacement.
PatellofemoralarthroplastyA patel lofemoral replacement
( ) is indicated for the man-
agement of isolated osteoarthritis of
the patellofemoral joint. It has to be
clear that this form of partial knee
replacement is not indicated for pat -
ellofemoral pain in the absence of rad -
iographically proven osteoarthritis.
Patient selectionPatellofemoral arthritis occurs in up
to 9% of patients over the age of 40
and 15% of patients over 60.7 Most
patellofemoral pain or arthritis can be
treated with nonoperative measures
such as activity modification, physi-
cal therapy, analgesics, braces, and/or
injections. Patellofemoral arthroplas-
ty may be an option for patellofemoral
arthritis when other treatment modal-
ities have failed.
Patients with chondromalacia of
the patella have been treated with
arthroscopic debridement with limit-
ed success.8 A patellectomy has been
used in the past as well. Unfortunate-
ly, a patellectomy has its own set of
problems, which include loss of exten-
sion power and increased risk of arth -
ritis in the tibiofemoral compartment.
Figure 2
IndicationsAccording to Lonner9 the indications
and contraindications for a patello -
femoral arthroplasty are isolated
patellofemoral osteoarthritis, post-
traumatic arthritis, or advanced chon-
dromalacia with eburnation on either
or both of the trochlear and patellar
surfaces. It is contraindicated in pa -
tients with medial or lateral joint line
pain or tibiofemoral arthritis or chon-
dromalacia. It is not felt to be appro-
priate for inflammatory arthritis or
crystalline arthropathy. It should be
used with extreme caution in a patient
who has a highly malaligned patello -
femoral articulation with a high Q
angle and is thus at risk for dislocation.
ResultsThe component for patellofemoral
arthroplasty consists of a metal troch -
lear component and a polyethylene
button that replaces the articular sur-
face of the patella. Good to excellent
results have been reported in short,
mid-term, and medium follow-up.
The results are reported as being 80%
to 90% good to excellent.9
ComplicationsThe complications after a patello -
femoral arthroplasty include patellar
snapping and instability. Additionally
the standard complications for uni-
condylar knee arthroplasty can be
included. There can be ongoing res -
idual anterior knee pain and dys-
function. There can be subsidence,
polyethylene wear, or loosening. Long-
term arthritis in the tibiaofemoral
joint can also occur.
ConclusionsPartial knee replacements may be an
option for a select group of patients.
There is renewed interest in partial
knee replacements with recently re -
ported good long-term outcomes,
complications similar to total knee
replacement, and the fall-back option
of a conversion to a total knee replace-
ment. For the unicondylar knee, it is a
more conservative option with a fast
recovery, good functional outcome,
and is a possible good option to a high
tibial osteotomy or total knee replace-
ment. The unicondylar knee is most
commonly done for isolated medial
compartment osteoarthritis and has
very specific indications. The patello -
femoral arthroplasty is possibly indi-
cated in patients with isolated patello -
femoral arthritic pain. The limited
reports on the patellofemoral arthro-
plasty suggest very good results.

ABSTRACT: While osteoarthritis re -
mains the most common indication
for total knee replacement, the num-
ber of primary total knee arthroplas-
ties performed annually has increas -
ed exponentially over the last 55
years. Outcomes have improved
with the use of careful preoperative
assessment, a range of component
options, and operative technique
guided by clear surgical goals.
Informed consent of any patient con-
templating total knee arthroplasty
must be obtained by discussing the
risks and benefits and explaining that
between 80% and 85% of patients
are satisfied after the procedure.
Major joint arthroplasty isundoubtedly one of thesurgical success storiesof modern times. The
number of primary knee arthroplas-ties performed annually increasedexponentially over the last half of the20th century and increased between16% and 44% during the first 5 yearsof the 21st century.1,2 The history oftotal knee arthroplasty began back in 1860, when the German surgeonThemistocles Gluck implanted thefirst primitive hinge joints made ofivory. Development really took offfollowing the introduction of theWalldius hinge joint in 1951: initiallymanufactured from acrylic and later,in 1958, from cobalt and chrome.3
Unfortunately, this hinge joint suffer -ed from early failure.
In the early1960s, John Charnley’s
cemented metal-on-polyethylene total
hip arthroplasty inspired the develop-
ment of the modern total knee replace-
ment.4 Gunston, from the same centre
as Charnley, went on to design an
unhinged knee that replaced both the
medial and lateral sides of the joint
with separate condylar components.
Improved biomechanics resulted from
the preserved intact cruciate and col-
lateral ligaments, which maintained
the stability of unlinked femoral and
tibial components, and a design that
allowed the centre of rotation to change
with flexion of the knee.5 The metal-
on-polyethylene condylar design—
completely replacing the femoral and
tibial articulating surfaces—was pur-
sued throughout the early 1970s at
centres across the world.6-11 The result
was an implant relying on component
geometry and soft tissue balance to
provide stability, with a large articu-
lating surface area to spread load and
minimize polyethylene wear. Incre-
mental improvements in component
materials, geometry, and fixation
continued throughout the 1970s and
1980s. More accurate sizing, the
option of patellafemoral replacement,
better instrumentation, and compo-
nents that allowed an increased range
of motion and a lower wear rate have
since been developed.

eased part of the joint with more nat-
ural kinematics or joint movement,13,14
the indications for its use are more
limited.
Indications andpreoperative assessmentOsteoarthritis, whether primary, post-
traumatic, or secondary to avascular
necrosis, osteochondritis, or sepsis, is
by far the most common indication for
total knee replacement. Inflammatory
arthritides make up the bulk of the
remaining indications. Diagnosis of
the underlying condition allows appli-
cation of appropriate nonoperative
treatment, while the functional impact
of disease upon the everyday life of
the patient determines the appropriate
timing of surgery. Mechanical symp-
toms—locking or giving way—may
be amenable to arthroscopic assess-
ment and treatment. The severity of
symptoms are assessed by noting
reduced walking distance, analgesic
use, and sleep disturbance. Ability to
climb stairs or inclines, use of walk-
ing aids or other orthotics, and exac-
erbating or relieving factors all build a
more detailed picture of disability.
Knee examination should include
assessment of gait, surgical scars, loc -
al ized tenderness, active and passive
range of motion, limb alignment, co -
ronal and sagittal plane ligament sta-
bility, and neurovascular status of the
limb. Other pathology contributing to
symptoms should be excluded by
examination of the back, hip, foot, and
ankle of the same limb.
Up-to-date and serial (if available)
radiographs of the knee should in -
clude an anteroposterior view as well
as true lateral and skyline patello -
femoral views of the involved knee
together with full long leg views if
there is significant deformity, previ-
ous fracture, or previous osteotomy of
the femur or tibia. An anteroposterior
pelvis and lateral radiograph of the
ipsilateral hip should be sought if there
are symptoms of groin pain or signs of
stiffness or pain on rotation of the hip.
Magnetic resonance imaging can be
used to assess for meniscal or liga-
mentous injury in appropriate cases,
but is generally not required for the
routine assessment of the painful
arthritic knee. Radiographs should
always be performed before MRI is
ordered; in many cases, the plain rad -
iographic findings will make MRI
unnecessary.
The option of total knee arthro-
plasty is typically discussed with pa -
tients at the point in their lives when
knee pain from arthritis is significant-
ly interfering with activities of daily
living. Informed consent requires a
full discussion of the risks and bene-
fits of surgery to ensure that patient
expectations are realistic. Generally,
between 80% and 85% of patients are
satisfied with their knee arthroplasty.
The most significant complication is
deep infection, which complicates
between 1% and 2% of operations and
may require further and repeated major
joint surgery. Arterial injury compli-
cates between 0.03% and 0.17% of
cases15 and peroneal nerve injury has
been reported in between 0.3% and
2.0% of patients.16 The 20-day post-
operative mortality rate of 0.2% is
increased above the age-matched pop-
ulation and is the same as that meas-
ured for total hip arthroplasty. The
mortality rate normalizes with the
age-matched population after the 70th
postoperative day.17 Mortality at 1
year following knee arthroplasty is
1.6%, which is half the mortality rate
of the age-matched population, demon-
strating that total knee arthroplasty
patients are a highly select group.18
Operative techniquePreoperative radiographic templating
for knee arthroplasty, while not as cru-
cial as for hip arthroplasty, does indi-
cate the size and shape of the tibial
bone to be removed and the compo-
nent type and size that is likely to be
required. It is particularly important
in cases requiring the extremes of
implant size to ensure that all likely
sizes are available, in cases of severe
deformity, and in cases where there is
severe bone loss.
ComponentsMost orthopaedic supply companies
manufacture a range of implant de -
signs, from cruciate ligament retain-
ing ( ) and posterior stabilized
( ) implants that usually pro-
vide sufficient stability in the primary
setting, through to megaprotheses for
replacing tumor or bone.
The level of built-in constraint, or
stability, required by a knee pros theses
depends upon whether the posterior
cruciate and collateral ligaments are
intact. If the posterior cruciate liga-
ment is compromised, as it is in most
rheumatoid knees, or there is fixed

coronal plane or significant flexion
deformity, then the PCL is replaced
by a cam and post, the design of which
controls sagittal plane kinematics.
A larger post can provide additional
side-to-side/coronal plane stability
( ). If the medial collateral lig-
ament is compromised, a hinged pros-
thesis is chosen to further improve
coronal plane stability ( ). In -
evitably this puts greater strain upon
the hinge itself and produces increas -
ed shear stresses at the implant inter-
face with the bone. A rotating hinge
allows movement in the axial plane
between the polyethylene and tibial
surface, decreasing these stresses but
producing a secondary surface for the
generation of wear debris. Modular
femoral and tibial stems are added to
the resurfacing implants in this scen -
ario to increase the area of fixation,
spreading load and decreasing stress-
es at the implant bone interface.
Femoral or tibial stems of varying
lengths may also be added if there are
significant uncontained bone defects.
Generally, a contained bony defect
with an intact cortical rim or an uncon-
tained defect of less than 5 mm can be
filled with cement upon implantation.
Contained defects greater than 5 mm
with an intact cortical rim can be treat-
ed with morcelized impaction bone
allografting. Uncontained defects re -
quire shaping to accommodate the
metal wedges that are added to the
implant. Larger defects are not com-
monly encountered in the primary set-
ting, but when present may require
bulk bone allograft. The addition of a
femoral or tibial stem provides addi-
tional stability and protects supple-
mented defects, minimizing the risk
of long-term implant subsidence.
Surgical goalsThe clinical aims of knee arthroplasty
are to provide the patient with a pain-
free, stable joint that will last a long

time. To achieve this, the surgical team
focuses on five surgical goals:
• Mechanical alignment of the limb.
The proximal tibia and the distal
femur are cut so that the mechanical
axis of the limb—from the centre of
the hip to the centre of the ankle
joint—passes through the centre of
the knee arthroplasty. This ensures
that forces are transmitted equally
through each side of the new joint,
optimizing the lifetime of the joint.19
Aligning the limb correctly also pro-
vides the correct starting platform
for achieving subsequent surgical
goals.
• Joint line preservation. The depth of
bone removed from the tibia and the
femur should be equal to the height
of the respective components that
are implanted. By taking out what is
to be put back in, the position of the
original joint line is preserved. This
optimizes the function of the liga-
ments and muscles acting upon the
knee.
• Soft tissue balance in the coronal
plane. Balancing the knee to varus
and valgus stress maintains equal
load transmission through each side
of the knee. Following many years
of disease, deformity in the coronal
plane can become fixed by contrac-
ture of soft tissues. Osteoarthritis
most commonly leads to a varus
deformity and tight medial soft tis-
sues, which are released in the fol-
lowing order to attain satisfactory
balance:
1. Medial osteophyte removal.
2. Proximal subperiosteal stripping
of the deep medial collateral lig-
ament.
3. Posteromedial capsular release.
4. PCL sacrifice requiring the use of
a posterior stabilized component.
5. Distal tibial periosteal stripping
of the MCL (avoiding complete
release and subsequent valgus
instability).
Rheumatoid arthritis or lateral
fem oral condyle hypoplasia can lead
to a valgus deformity that requires the
following releases to attain satisfac -
tory balance:
1. Lateral osteophyte removal.
2. Subperiosteal dissection of the lat-
eral joint capsule.
3. Lateral patellofemoral ligament
release.
4. “Pie crusting” of the iliotibial band
if tight in extension.
5. Popliteus release if tight in flexion.
6. PCL sacrifice requiring the use of a
posterior stabilized component.
7. Lateral collateral ligament release
from its femoral insertion (avoid-
ing complete release and subse-
quent varus instability).
• Balance of the flexion and extension
gaps in the sagittal plane. This re -
sults in the knee maintaining stabil-
ity throughout its full range of mo -
tion. Flexion instability occurs when
the gap between the tibia and the
femur is wider in flexion than in
extension and must be corrected to
ensure the patient is asymptomatic.
Recurvatum or extension beyond
0 degrees may result from a “loose”
extension gap. A “tight” flexion or
extension gap may restrict the full
range of flexion or extension. Loss
of full range of motion at either
extreme can be disabling. Loss of
full flexion can make stair and hill
climbing difficult. Loss of full ex -
tension makes complete lockout of
the knee impossible and requires
prolonged quadriceps muscle en -
gagement—which is tiring for the
patient—when standing in one spot.
A tibiofemoral gap consistent
throughout a full range of motion
can be achieved by using an appro-
priately sized tibial insert combined
with a femoral component implant-
ed in the correct position.
• Q angle correction. This is the angle
between the quadriceps and the
patella tendon and is a function of
the positioning of the tibial, femoral,
and, if used, patella component. In
particular the femoral component
requires appropriate positioning in
all three planes to allow the patella
to track correctly.
Each of these goals may not nec-
essarily be addressed in strict order
during surgery. Indeed, some of the
steps involved during the procedure
may address more than one goal at the
same time. For instance, sizing and
positioning the femur ensures balance
of the flexion and extension gaps as
well as creating a Q angle that affords
correct patella tracking. What is vital
is that every goal be considered in
order to produce a pain-free, stable
joint that will last a long time.
The operationFollowing complete preoperative
assessment and planning to ensure
correct implant availability, a typical
total knee arthroplasty would proceed
as follows:
• Intravenous antibiotics are given
well before inflation of a proximal
thigh tourniquet to 300 mm Hg.
• The skin is prepped and draped to
allow an adequate midline longitu-
dinal incision to access the knee
joint, usually via a medial parapatel-
lar approach.
• Part of the anterior fat pad, remnants
of the medial and lateral menisci,
the anterior cruciate ligament and
the PCL (if a posterior stabilized
implant is to be used) are excised.
Osteophytes are excised and the
proximal medial soft tissues are
released to allow visualization of the
edge of the medial tibial plateau and
forward subluxation of the tibia in
full flexion and external rotation.
Further preliminary soft tissue re -
leases are performed at this stage as
appropriate.
• The tibia is cut at 90 degrees to its
Total knee arthroplasty: Techniques and results

mechanical axis using an extra -
medullary or intramedullary jig.
Tibial bone is removed from the
normal side of the joint to the same
depth—usually 10 mm—as the
height of the tibial component to be
implanted, with the aim of preserv-
ing the position of the original joint
line.
• The femoral intrameduallary canal
is entered and the appropriate jig
is used to cut the distal femur in
between 5 and 7 degrees of valgus
relative to the anatomical axis. This
ensures the bone is cut at 90 degrees
to the mechanical axis of the femur,
thus satisfying the first surgical
goal of knee arthroplasty. Femoral
bone is removed to the same depth—
again, usually 10 mm—as the height
of the femoral component to be im -
planted, with the aim of preserving
the position of the original joint line.
• The extension gap is checked to
ensure a 10-mm spacer can be insert-
ed. If it cannot, the tibia or femur, as
appropriate, are recut by an appro-
priate amount—usually 2 to 4 mm.
Overall alignment of the bony cuts
is checked to ensure the limb is
straight and the soft tissues balance
to varus and valgus stress. Further
adjustments of the bony cuts and
further soft tissue releases proceed
if required.
• The femoral size is measured (in
the anteroposterior and mediolateral
plane) and correct position of
the femoral cutting block in the
sagittal (anteroposterior transla-
tion), the coronal (mediolateral
translation), and axial plane (rota-
tion) is ensured.
• The posterior femoral condylar cut
is made to enable trialing of the 10-
mm spacer block at 90 degrees of
flexion to confirm that the flexion
gap matches the extension gap be -
tween the tibia and the femur.
• The remaining femoral bony cuts
are made to match the inside of the
femoral component, and a drill hole
is made in each condyle to accom-
modate the two femoral pegs.The
trial components are inserted with
the appropriate tibial spacer. The
patella is prepared if it requires
replacement, and is rechecked prior
to final implantation. The optimum
position of the tibial component is
marked and preparation of the tibial
keel is completed.
• The cancellous bone surface is clean -
ed and the real components cement-
ed with antibiotic-loaded cement.
Compression is applied with the knee
in extension through a trial insert.
Once the cement has hardened any
loose cement is removed and the
appropriate real polyethylene insert
is implanted.
• The tourniquet is released to con-
firm hemostasis. A single drain is
used and the retinacular-tendinous
layer is closed with interrupted sut -
ures. The subdermal tissues and skin
are closed and dressings applied.
Postoperative careTwo further intravenous doses of anti -
biotics are given to cover the first 24
hours. Low molecular weight heparin
or a similar suitable anticoagulant is
prescribed—according to patient risk
assessment—usually up until the 10th
day postoperatively to ensure optimal
thromboprophylaxis. The patient is
mobilized, fully weight bearing in the
majority of cases, as soon as the gross
effects of the anesthetic have worn off.
Patients are encouraged to maximize
knee extension and flexion at every
stage of their recovery to ensure opti-
mal outcome. Exercises are commen -
ced to ensure full recovery of quadri-
ceps tone and strength and analgesia
is provided to ensure the best possible
results from physiotherapy. Discharge
from hospital is allowed when the
wound is dry and the patient is safe
ascending and descending stairs.
Sutures or skin clips are removed at
10 to 14 days. A walking aid may be
required for several weeks following
surgery. The literature supports driv-
ing from 8 weeks, so long as the pa -
tient is clear of opiod analgesia and
can perform an emergency stop.20 Fol-
low-up appointments are scheduled at
6 to 8 weeks, 1 year, 5 years, and every
subsequent fifth year thereafter. Earli-
er follow-up should be requested if
there is any sign of infection or other
significant concern. Over 85% of total
knee arthroplasty patients will recover
knee function following a general
rehabilitation protocol. The remain-
ing 15% of patients will have difficul-

ty obtaining proper knee function sec-
ondary to significant pain, limited pre-
operative motion, or the development
of arthrofibrosis. This subset of
patients will require a more specific
prolonged rehabilitation program that
may involve ongoing oral analgesia,
continued physical therapy, additional
diagnostic studies, and occasionally
manipulation. Controlling pain is the
mainstay of any such treatment plan.21
ResultsThe survivorship rate is the percent-
age of total knee arthroplasties that
have not been revised in any given
series of patients. It is generally the
most often quoted outcome in the joint
arthroplasty literature. Survivorship
is arguably the most useful outcome
when distinguishing between differ-
ent prosthetic designs and also helps
answer the patient question, “How
long will the knee last?”
The pioneers of total knee arthro-
plasty saw early failures that quickly
led to the use of more durable materi-
als, better fixation, and improved de -
sign.5-11 Published longer-term results
have shown markedly differing sur-
vivorship rates between more subtle
differences in arthroplasty design. In
a recent study looking at 3234 knee
arthroplasties performed between
survivorship rates of 100% at 10 years
are seen with the Miller-Galante II
knee, which was redesigned to solve
the high rate of patellofemoral com pli-
cations seen with the Miller-Galante I
(which still had an 84.1% survivorship
rate at 10 years).28 Studies comparing
the results of different design options
manufactured by the same company
are now also available: the 10-year
Genesis knee results for the (posteri-
or) cruciate retaining knee reveal 97%
survival compared with the Genesis
posterior stabilized knee, which has
96% survival—an insignificant differ-
ence.29 The results of unicompartmen-
tal knee arthroplasty have been as
good as total knee arthroplasty in pub-
lished individual series, with sur-
vivorship rates of 98% at 10 years.30,31
It is arguably the recent registry
data for newer generation knee im -
plants that apply most readily to the
average patient considering total knee
arthroplasty. The 8-year survivorship
rate for the eight most common knee
joints in current use in Norway is
between 89% and 95%1 and the 7-year
rate in Australia is 95.7%.2 Of note,
purely in terms of survival, these reg-
istries have found inferior results for
even the best-performing unicompart-
mental knee arthroplasties when these
are compared with total knee arthro-
plasty. The cumulative survival at 7
years for unicompartmental knees in
Australia is only 88.1% compared
with 95.7% for total knees.1,2 This may
relate to issues of patient selection or
reflect the increased technical expert-
ise required for this procedure. Con-
version of unicompartmental knee
arthroplasty to total knee replacement
is relatively straightforward, so appro-
priate patients seeking a partial knee
replacement should not be discour-
aged by the slightly lower long-term
survivorship seen in registry data.
Several knee scores have been
developed to assess outcome follow-
Total knee arthroplasty: Techniques and results
1969 and 1995, 89% of the condylar
designs had survived 10 years and
between 78% and 89% had surviv ed
15 years.22 Survivorship rates, how ever,
varied considerably among different
implant designs. The corresponding
rates for some, now discontinued,
designs in this same study were
between 43% and 63% at 10 years
and between 28% and 59% at 15
years.22 Further studies have confirm -
ed clinical survival of the total condy-
lar knee design of 94% at 15 years23
and be tween 77% and 91% at 21 to 23
years.24,25 For this reason the total
condylar design has endured. Perhaps
the best long-term published results
are for the Anatomic Graduated Con -
dy lar (AGC) knee arthroplasty, the
success of which is attributed to a
straightforward design that utilizes
carefully manufactured materials. The
AGC knee has a published survivor-
ship rate of 98.9% in 4583 knees at 15
years26 and a rate of 97.8% in 7760
knees at 20 years—quite impressive
survivorship. The number of knees
that reach long-term follow-up in such
series are, however, often small; only
36 of the 7760 knees in this study
made it to the 20-year point.27
Medium-term follow-up is becom-
ing available on updated versions of
the total condylar design. Improved
Improved survivorship rates of 100% at
10 years are seen with the Miller-Galante II
knee, which was redesigned to solve the

ing total knee arthroplasty. These tools
produce numbers that correspond to
excellent, good, fair, or poor outcome.
For example 92% of knees were as -
sessed as good or excellent in one
study, with 1.6% fair and 6.5% poor.23
Between 96% and 98% of knees were
assessed as good or excellent in anoth-
er study.29 However, more recently it
has been shown that the views of sur-
geons and their patients regarding the
outcome of surgical interventions do
not always correlate well—especially
with respect to function and pain.
Patient questionnaires are thought to
better assess patient outcome, and in a
recent study 81.8% of 8095 patients
were satisfied, 11.2% (906 of 8095)
were unsure, and 7.0% (566 of 8095)
were not satisfied with their new knee
joint.32
With regard to younger patients
under the age of 55 years, a survivor-
ship rate of 96% of 93 knees was
observed at 10 years,33 and of 90% of
108 knees at 18 years;34 94% of pa -
tients in the latter study had good or
excellent function and all but two
patients had improvement in their
activity score postoperatively. Fur-
thermore, 24% regularly participated
in activities such as tennis, skiing,
bicycling, or strenuous farm or con-
struction work.34 This suggests that
the traditional practice of withholding
knee replacement until patients are
over 65 or over is not warranted, and
replacement should proceed when
clinically appropriate.
It was traditionally thought that
obese patients do not fare as well as
normal-weight patients following
joint replacement. Postoperative out-
come scores for obese patients, how-
ever, were found to be comparable to
scores for patients who were not obese
in one recent study. Furthermore,
given the lower preoperative scores
measured in the obese group, the over-
all improvement was actually greater
than in the normal-weight group.
Additionally, survivorship rates in
obese patients were not significantly
lower than in patients who were not
obese at 10 years follow-up.35 There
was, however, a greater proportion of
lucent lines seen on the radiographs
around the implants of the obese
patients23,35 and in the morbidly obese
the complication rates are higher and
the implant survivorship rate is lower.
The final objective measure of
outcome perhaps most relevant to the
individual patient is range of flexion.
This has gradually improved from a
mean of 99 degrees23 to between 114
and 117 degrees with newer genera-
tion designs.29 Postoperative range of
motion largely depends on the preop-
erative range of motion. Generally,
what the patient has before the opera-
tion is what the patient can expect to
achieve after surgery and rehabilita-
tion.36 Patients seeking knee replace-
ment should be counseled that their
postoperative knee will not be “nor-
mal,” but it will feel and function
much better than their preoperative
arthritic knee.
ConclusionsOsteoarthritis remains the most com-
mon indication for total knee arthro-
plasty. Fortunately, technical devel-
opments over the last half century
have resulted in 10-year survivorship
rates of 90% and higher, and between
80% and 85% of patients have been
satisfied with their total knee replace-
ment. Further incremental improve-
ments in knee arthroplasty engineer-
ing, implant design, and material
science will continue to improve bear-
ing surface tribology, implant fixa-
tion, and implant longevity. These
advances will all help meet the main
surgical goals of total knee arthro-
plasty: to correct limb alignment, pre-
serve joint line position, balance the
soft tissues in the coronal plane, bal-
ance the flexion/extension gap in the
sagittal plan, and create a Q angle that
facilitates satisfactory patella track-
ing. Preoperative assessment and
planning will also help meet these
goals by ensuring patient expectations
are realistic and informed consent has
been obtained after a full discussion
of the risks and benefits of surgery.

ABSTRACT: Primary total hip arthro-
plasty has become one of the most
successful surgical procedures over
the past 50 years and is currently
performed worldwide with similar
techniques and excellent results.
Despite variations in technique and
implant selection, medium and long-
term outcome studies have demon-
strated over 90% implant survival at
15 to 20 years. Previous problems
with implant fixation have now been
reduced, and the focus has shifted
to the selection of improved bearing
surfaces to limit wear, hip replace-
ment options for younger patients,
and improved surgical and anesthet-
ic techniques. Current surgical ap -
proaches to the hip rely most often
on direct lateral or posterolateral
exposure. The most commonly uti-
lized bearing surface for both hip
replacement and hip resurfacing in
Canada is a metal (cobalt-chrome)
femoral head combined with a
second-generation cross-linked poly-
ethylene, combined with cementless
implant fixation. Alternative bear-
ings such as ceramic-on-ceramic
and metal-on-metal may be consid-
ered for hip replacement in younger
patients. Although it has not been
determined which surface will prove
best for younger patients in the long-
term, there is no question about the
benefits of total hip arthroplasty.
With current techniques, the results
are favorable, and patient satisfaction,
pain relief, and long-term implant
survival are excellent.
The current long-term suc-cess of total hip replacement(THR) surgery has led to theobservation by Coventry1
that “total hip replacement, indeed,might be the orthopaedic operation ofthe century.” The indications for THRhave expanded to such an extent thatthis surgery is no longer performedonly in the elderly or in those with de -bilitating hip pain, arthritis, and severefunctional restrictions. Rather, THR isnow performed in younger and higher-demand patients, with expectations,quality-of-life measures, and inten-tions to return to prior activity levelsthat challenge surgical techniques andimplant design technology. The ad -vantages of THR generally outweighthe disadvantages ( ), and atten-tion is now focused on improved fix-ation of the implants, reduction in therates of failure, and development ofbearing surfaces to reduce long-termwear and improve implant longevity.
Surgical exposureSeveral surgical exposures are utiliz -
ed for THR. The two most common

ex posures ( ) are the anterolat -
eral2 and the posterolateral approach-
es to the hip.3 Patients may also be
offer ed one of the newer techniques of
surgical exposure referred to as muscle-
sparing or minimally invasive. The
decision of which surgical exposure
to use will depend upon surgeon expe-
rience and preference, patient body
habitus (i.e., obesity), patient ana tom-
ical factors, the location and type of
prior surgical incisions over the hip,
and implant selection. The most im -
portant factor to consider is surgeon
experience and preference.
The anterolateral exposure is an
abductor-splitting approach requiring
removal and repair of the anterior 30%
to 40% of the gluteus medius and min-
imus. This approach may also be uti-
lized for revision THR surgery. Many
surgeons select this approach based
upon the potential for a reduced dislo-
cation rate. Disadvantages of the an -
tero lateral approach include:
• An increase in limp due to splitting
of the abductor muscle (also likely due
Figure 1 to traction injury to anterior branch-
es of the superior gluteal nerve dur-
ing surgery). Often the limp is re -
ported as being asymptomatic, but
frequently it is a Trendelenburg gait.
• An increase in the formation of het-
erotopic bone within the abductor
muscles and anteriorly over the cap-
sule and greater trochanter.
• A greater incidence of trochanteric
complications (intraoperative frac-
ture, postoperative fracture, or es -
cape of the greater trochanter), and
trochanteric pain (often incorrectly
attributed to a diagnosis of tro -
chanteric bursitis), most likely due
to failure of the ab ductors to heal
following the repair.
• A tendency for the surgeon to insert
the femoral component angled from
anterior to posterior within the fem -
oral canal (i.e., nonanatomic femoral
component placement).
With the popularity of less inva-
sive surgery, the posterolateral expo-
sure has again gained prominence.
Disadvantages of the posterolateral
approach include:
• Perhaps a slightly higher risk of dis-
location, although with experience
this is minimized.
• The need for careful attention to
component orientation in order to
insert the implants in proper antev-
ersion.
In Canada between 2008 and 2009,
the direct lateral approach (60%) and
posterolateral approach (36%) com-
bined for over 95% of all surgical
exposures.4 When minimally inva-
sive surgery for THR is performed, it
is most commonly performed using
one of these two approaches. Other
minimally invasive surgical approach
options include the two-incision ap -
proach,5,6 the anterolateral (Watson-
Jones) approach, and the direct ant e-
rior (Hueter) approach.7 Often these
surgical approaches require the sur-
geon to change to a different OR
setup6 (i.e., one with a specialized
table, retractors, and lights, and access
to intraoperative X-ray) and to use an
implant he or she may be less familiar

with in order to make the procedure
feasible. While there may be a few
short-term advantages to minimally
invasive surgery, the early and mid-
term results have been associated with
significantly increased risks and sur-
gical complications,5 which have not
been seen in THR prior to the popu-
larity of these techniques. Thus, the
enthusiasm for minimally invasive
surgery has declined recently in favor
of surgery performed safely through
smaller incisions, and with the goal of
achieving an ideal implant orientation
and longevity. Computer-assisted
surgery (CAS) for total hip replace-
ment has gained popularity and is per-
formed in many centres. The advan-
tages and results of CAS have been
difficult to assess, and there does not
appear to be any significant advantage
to CAS at this time. The one area of
potential advantage is that CAS may
be useful in identifying “outlier”
acetabular component position/angu-
lation and leg length and hip offset
intraoperatively, which might help in
select situations, especially for sur-
geons with less experience perform-
ing THR and surgeons combining
CAS with minimally invasive surgery.
The main disadvantage is increased
OR time and increased cost. Overall,
CAS has not been shown to be cost-
effective to date.
Implant fixation:Cemented or cementless? Both cemented and cementless fixa-
tion are currently utilized in THR sur-
gery, although there has been a trend
in North America toward cementless
implants over the past 10 years. Total
hip replacement implants typically
consist of the acetabular component
(which is fitted into the patient’s
native acetabular pelvic bone with or
without cement), the femoral compo-
nent (inserted down the femoral
canal), and the bearing surfaces (the
articulating aspects of the implant).
When describing fixation methods,
we are referring to the femoral and
acetabular components.
Acetabular component implant fixationThe use of cemented acetabular com-
ponents has declined in recent years in
North America, although cemented
components are still used occasional-
ly in older and lower-demand patients.
When compared with cementless im -
plants, cemented acetabular compo-
nents have been associated with in -
creased rates of loosening at 10 to 20
years, especially in patients younger
than 50,8 when compared to cement-
less implants. Cementless acetabular
fixation was introduced to solve the
problem of loosening with cemented
acetabular cups. The most commonly
used composite for cementless acetab-
ular components is titanium alloy,
which is favorable for bone ingrowth.
Typically, a modular bearing surface
(the liner) is inserted into the inner
aspect of the acetabular component,
and locks into place via a mechanism
contained within the acetabular com-
ponent. The acetabular component
may accept bearing surfaces, including
liners made of polyethylene, ceramic,
or metal, to complete the acetabular
component composition ( ).
This modular bearing surface may be
exchanged in the future if wear or
other less common indications make
this necessary, leaving the intact
osseo-integrated acetabular compo-
nent in place. The long-term results of
cementless titanium acetabular fixa-
tion have been favorable. At a mini-
mum of 20 years, the implant survival

for titanium hemispherical cups has
recently been reported at over 95%.9
However, wear-related complications
of the polyethylene liner inside and on
the backside (and of the associated
modular locking mechanism) occur in
approximately 20% of patients by 20
years, a problem that has become the
focus of research in THR surgery.
Femoral component implant fixationCemented femoral component fixa-
tion has achieved excellent long-term
results in multiple studies at 17 to 30
years10-14 and continues to be the gold
standard against which the more pop-
ular cementless femoral fixation must
be measured. Contemporary cement-
ing techniques were refined in the
1970s and require attention to detail.
In addition to cement technique, there
are two implant designs: the cemented
tapered polished collarless stem (Ex -
eter, Stryker Orthopaedics, Mahwah
NJ) and the Spectron EF stem (Smith
& Nephew Orthopaedics, Memphis
TN) ( ) which have incor po-
rated differing design characteristics,
yet which have both proven very
successful in the long-term clinical
trials.15,16 Early failures of cemented
stems implanted with older cementing
technique included loosening, stem
fracture, and localized areas of bone
destruction (osteolysis) from cement
wear debris. Cementless implants were
developed to solve these problems.
Today, cementless femoral compo-
nents are produced in various designs
and shapes, and with different metal-
lic compositions and surface prepara-
Figure 3
tion to promote osseo-integration. All
uncemented femoral stem designs rely
on metaphyseal fixation, metaphy-
seal-diaphyseal junction fixation, dia-
physeal fixation, or a combination of
the three. The tapered titanium alloy
cementless stem ( ) has grown
in popularity17 and is becoming com-
monly used worldwide. Achieving
a press-fit via a single or dual taper -
ed wedge with subsequent proximal
osseo-integration of bone has proven
successful in multiple long-term stud-
ies18 of tapered titanium stems, with
over 95% survival at 10 to 20 years.
In summary, while cemented fem -
oral stem fixation remains the gold
standard in long-term studies, it is
highly dependent on cementing tech-
nique and implant design. Cemented
acetabular fixation is rarely utilized in
North America. Cementless fixation
on both the femoral and acetabular
sides is performed most commonly
and relies on an immediate press-fit
of the implant followed by osseo-
integration into host bone.
Hip resurfacing Total hip resurfacing, also known as
surface replacement arthroplasty or
hip resurfacing (HR), has gained in
popularity partly because of two
metal-on-metal HR implants approv -
ed by the FDA within the past 9 years.
HR has been performed for 15 years
in both North America and Europe
with favorable results.19,20 It is per-
formed using a cemented metal fem -
oral component shaped to the patient’s
native femoral head and a cementless
acetabular component with a polished
inner cobalt-chrome metal surface
( ). The two surfaces join to
create a metal-on-metal bearing
surface that has low-wear properties.
Relative indications for HR surgery21
include younger age, active occu-
pational and lifestyle requirements,
favorable bone anatomy and quality

(without cystic change, defects, or dys-
plasia), normal weight, and male sex.
Hip resurfacing may also be used ad -
junct when there is proximal femoral
deformity that would otherwise re -
quire an osteotomy to perform a THR
( ). Contraindications include
impaired renal function (or the poten-
tial for impairment with a diagnosis
such as diabetes) with an inability to
process serum metal ions, older age,
osteoporosis or osteopenia, unfavor-
able femoral head geometry, clinical
metal sensitivity history (usually a
nickel sensitivity), a leg-length discrep-
ancy greater than 1 cm, and women of
childbearing age. The primary con-
cern regarding HR in younger women
is how the increased ion levels of
cobalt and chromium normally asso-
ciated with a metal-on-metal bearings
could effect fetal development, as
these ions do cross the placenta. Two
recent studies suggest that although
these ions cross the placenta, a modu-
latory effect oc curs, decreasing their
concentration in the fetus. Still, such
Figure 6
results should be interpreted with
caution.22,23
Hip resurfacing surgery is perform -
ed with similar exposures to those
used in conventional THR. Contrary
to popular belief, hip resurfacing is
not a minimally invasive procedure.
Rather, it often requires a larger inci-
sion and surgical exposure, with addi-
tional soft tissue capsular releases that
are not typically performed in THR—
thus HR is often more invasive, not
less. Despite this, recovery following
hip resurfacing is similar to conven-
tional THR, likely due to generally
younger patient age. The proposed
advantages (which remain controver-
sial) of HR surgery include:
• Bone preservation on the femoral side.
• Ease of future revision surgery on
the femoral side.
• Large-head bearing surface with a
reduced dislocation rate.
• Use of a metal-on-metal low-wear
bearing surface.
• Patient findings that HR feels more
normal than THR.
These advantages, however, can
all be obtained from conventional
THR with the use of a metal-on-metal
bearing surface, particularly if a large
femoral head is used.
Surgeons who disfavor hip resur-
facing do so for several reasons:
• Bone preservation may not neces-
sarily occur, with occasionally more
bone being removed on the ace tab-
ular side to achieve a deepened sock-
et with a press-fit and no option for
screw fixation.
• The risk of notching the femoral neck
and subsequent femoral neck fracture
(risk 0.8%–1.5%)24,25 ( ).
• Elevated levels of serum and urine
cobalt, chromium, molybdenum, and
selenium ions that remain elevated
lifelong.
• The risk of lymphocyte-mediated
metal sensitivity reactions and/or
the development of pseudotumors,
recently highlighted in research at
UBC and McGill University.26
• It is a technically more demanding
surgical procedure for the surgeon

and team, with a steep learning
curve27 and potentially increased
risks and complications when com-
pared with conventional THR.
While HR is an option to consider
in younger and more active patients, it
requires careful preoperative assess-
ment and a discussion with the patient
about all of the issues, including the
risk of increased metal ion levels and
metal sensitivity reactions, and the
low risk of psuedotumor.28 In addi-
tion, impact activities are not encour-
aged after HR, and the restrictions and
precautions following surgery are
similar to those for THR. Overall, the
short-term results of HR (up to 5
years) have been worse than for THR,
and therefore hip resurfacing should
be used with caution. THR remains
the gold standard.
Bearing surfacesWith current implant fixation meth-
ods demonstrating excellent long-
term results, the bearing surface
in THR is now the focus of much
research. The bearing surface is where
the movement of the two bearings
occurs and which provides the range
of motion and articulation of the pros-
thetic ball and socket joint. Within the
last 10 years, the use of traditional
ultrahigh molecular weight polyethyl-
ene (UHMWPE) acetabular liners has
declined with the development of new
kinds of polyethylene.
Highly cross-linkedpolyethylenesTo reduce wear rates and particulate
debris, highly cross-linked polyethyl-
ene (XLPE) has been used in total
hip arthroplasty for 8 years. The man-
ufacturing process for these materials
cross-links the molecules and im -
proves wear characteristics but slight-
ly reduces the strength of the polyeth-
ylene. Free radicals may be generated
in the process, potentially allowing
for oxidative changes in the polyeth-
ylene, unless these changes are appro-
priately managed in the manufactur-
ing process. Thus, the ideal XLPE
would be cross-linked at an appropri-
ate level of radiation, and then remelt-
ed to remove these free radicals and
thus reduce the oxidation process.
Cur rently, all of the THR implant
manu facturers produce either a first-
generation or second-generation XLPE.
When combined with a polished
cobalt-chrome head of multiple sizes,
these new XLPEs have shown prom-
ise in reducing in vivo and simulator
wear measurements significantly29
compared with traditional UHMWPE.
The increase in wear resistance is,
however, associated with a decrease
in fatigue strength and toughness. The
use of XLPE liners requires meti cu-
lous positioning of the acetabular
component to avoid vertical place-
ment of the implant, which reports
have associated with an increased risk
of fracture at the rim of the polyethyl-
ene liner ( ). The use of XLPE
has allowed the introduction of larger
femoral heads, which increase the sta-
bility of the hip with their greater dia -
meter and increased “jump distance.”
When XLPE is used, wear rates of the
polyethylene have not been shown to
be worse with larger femoral heads.
This is in contrast to older UHMWPE,
which demonstrates higher volumet-
ric polyethylene wear as the size of
the femoral head is in creased.
Alternative bearing surfacesOther bearing surfaces have been
developed and utilized in THR in an
attempt to reduce the wear-related
polyethylene complications. Polyeth-
ylene wear and debris formation result
in hip joint synovitis, joint instability,
osteolysis, and, potentially, prosthesis
loosening. Alternative bearing surfaces
such as metal-on-metal, ceramic-on-
ceramic, ceramic-on-XLPE, oxinium
(oxidized zirconium), and even the
new XLPEs themselves have been
developed in an attempt to reduce
wear and improve implant survival in

younger and more active patients.
Currently in Canada, the most com-
monly utilized bearing surface is a
cobalt-chrome head combined with
cross-linked polyethylene (59%),
while other alternative bearings such
as metal-on-metal (11% ; includes HR
use) and ceramics (13%) are used less
frequently, and usually in younger
patients.4
Ceramics. Alumina ceramics were
introduced in the 1970s. They have a
very low coefficient of friction and
demonstrate the lowest wear rates of
any implant bearing surface.30 They
are scratch resistant and may be com-
bined as a modular ceramic acetabular
liner with a ceramic head. There is no
potential for metal ion release, which
is attractive to younger patients, espe-
cially females of childbearing age.
Although ceramics can fracture be -
cause of their brittle composition, the
rate of fracture is very low (0.5%)31 in
most studies. Newer ceramic compos-
ites of alumina (Biolox Delta Ceram-
ic, CeramTec AG, Lauf, Germany)
have demonstrated increased strength
and fracture resistance, and offer
increased neck-length options intra-
operatively ( ). Ceramic-on-
ceramic bearing surfaces have been
associated with squeaking that is audi-
ble to the patient and others. Initially
believed to occur rarely (~1%) in
ceramic-on-ceramic THR, recent stud-
ies have shown that noise (squeaking,
grinding, rubbing, or other audible
Figure 9
sounds from the hip) occurs more fre-
quently than originally re ported, and
is experienced by 10% to 17% of
patients with a ceramic-on-ceramic
bearing surface.32,33 The causes and
implications of squeaking have yet to
be determined, but are likely to be
multifactorial: acetabular modular
implant design-specific factors, com-
ponent orientation and malposition,
instability, and femoral component
design have all been implicated. The
use of ceramic-on-ceramic bearings
offers many advantages in terms of
wear reduction, especially for young
and active patients. Nonetheless, pa -
tients considering ceramic-on-ceramic
bearings should be informed of this
phenomenon, and the surgeon and

patient should discuss avoiding cer -
amic implants associated with a high-
er incidence of squeaking. There are
no long-term clinical results to date
for the newer ceramic composites.
Oxinium. Oxidized zirconium (Smith
& Nephew, Memphis, TN) has been
developed for femoral head compo-
nents and has the wear-resistance of
ceramic without the brittle fracture
risk. Compared with the limited cera -
mic ball neck lengths available, oxini-
um allows for increased length op -
tions intraoperatively. No long-term
clinical studies of this material have
been published yet, and it is only avail-
able from one manufacturer.
Metal-on-metal. Metal-on-metal bear-
ing surfaces have been used widely
since the 1960s.34-36 Poor metallurgy,
poor design (equatorial head edge bear-
ing), and poor fixation led to early fail-
ures of many hip replacements using
metal bearings. However, a subset of
these were found to have a suitable
central-head bearing and minimal wear
when compared with hip replace-
ments using UHMWPE. This finding
led to a resurgence of interest in metal-
on-metal surface bearings, and an
attempt to create a bearing surface
with similar metallurgy and design to
that found in the subset with long-term
survival. Metal bearing surfaces dem -
onstrate very low wear rates—some-
where between rates for ceramic-on-
ceramic and metal-on-XLPE—and
much less wear than for conventional
UHWMPE. Metal bearings support
the use of a larger femoral head size,
which demonstrates better fluid-film
lubrication, and lower metal ion lev-
els than found with smaller head com-
binations, making metal-on-metal
ideally suited for hip resurfacing.
Metal is not brittle like ceramic, mak-
ing it attractive for younger patients.
Larger head sizes are also associated
with improved joint stability and a
reduced risk of dislocation. While
metal-on-metal bearing surfaces gen-
erally are associated with elevated
metal ion levels,37 no long-term effects
are known. Preoperatively, patients
must be informed that the low risk of
metal sensitivity and lymphocyte-
mediated reaction is similar to that for
hip resurfacing. Recently, inflamma-
tory granulomatous pseudotumors,
which are necrotic cystic soft tissue
tumors, have been seen following
large-head metal-on-metal hip replace-
ment with one or more implant de -
signs, and have been seen less often
following HR. For this reason, metal-
on-metal bearing surfaces should be
used with caution in THR, patients
should be followed closely at yearly
intervals, and patients should be coun-
seled about the possibility of metal-
related complications that will lead to
poor outcome if they occur, even after
revision surgery.
ConclusionsTotal hip arthroplasty has become the
treatment of choice for hip-related dis-
orders leading to arthritis in the adult
population. With improvements in
long-term clinical results, implant fix-
ation, and new low-wear bearing sur-
faces, THR surgery is now being per-
formed in younger and more active
patients. Using current implant design
and techniques, the implant survival
at 20 years is favorable, with over 90%
implant survival in multiple studies.
However, with younger and more
active patients undergoing total hip
replacement, the challenge will be the
bearing surface selection. It remains
to be determined which bearing sur-
faces will provide the lowest wear
rates and the fewest wear-related com-
plications in the long term.

Confidentially, could you resist
looking at your pattern of an -
ti biotic prescribing and com-
paring it with evidence? Without any-
one else knowing? If you are a GP in
active practice, you will soon receive
a sealed, coded envelope containing a
confidential portrait (seen by no one)
of your prescribing of antibiotics for
urinary tract infections (UTI). Its goal
is to reverse recent growth in antibi-
otic resistance. Yes, we can! Studies
have demonstrated the potential for
reduced antibiotic resistance follow-
ing reduced antibiotic prescribing.1
Ten years ago, BC’s provincial
health officer published a report on
antimicrobial resistance which con-
tained recommendations for areas of
action.2 It is fair to say that consider-
able progress has been made on most
of the recommendations related to the
piratory tract infections (URTI). The
portraits will be mailed out in a stag-
gered manner in coming months, so
impacts on prescribing can be asses -
sed comparing geographic areas that
receive the portraits early versus de -
layed areas.
Now that we are finally making
progress in putting our own house in
order, we should applaud BCMA’s
endorsement of investigation into the
deleterious effects on nonveterinary
use of antibiotics in agricultural opera -
tions.4 The effects on the environment
and the contribution to emergence
of antibiotic-resistant organisms in
humans must be understood and
addressed.5 While trends in human use
in BC are slowly improving, we have
made little or no progress on the issue
in agriculture and veterinary practice.
In several countries in northern Europe,
strict controls apply in agriculture.

and then levelled off. Between 2005
and 2008 we saw an 8.7% re duction in

a 17% reduction with acute pharyn-
gitis. There has been a 35% to 57%
reduction in use of anti biotics in chil-

children less than 1 year of age.
Unfortunately, the use of antibi-
otics with acute bronchitis remains
high. Ominously, the overuse of fluo-
roquinolones now threatens to render
this class of antibiotic ineffective for
treating urinary tract infections (UTI)
as E. coli resistance surges. Despite
guidelines stating that moxifloxacin
should be used only after another
antibiotic, preliminary data suggest
the vast majority of prescriptions for
this drug in BC in 2009 were not pre-

The Netherlands recently cele-
brated the 65th anniversary of
its liberation by Canadian Arm -
ed Forces on 5 May 1945 from Nazi
Germany. These celebrations were
attended by a dwindling number of
Canadian veterans present on that his-
toric day. It was a joyous occasion and
the Dutch turned out in force.
One Canadian veteran missing was
Lieutenant Colonel Russell Palmer
(Retired), who died 22 December
1999, aged 94.1 Dr Palmer’s major
contribution to the initiation and sub-
sequent growth of our renal failure
program, now the equal of any in
Canada, is seldom re membered in his
home pro vince of British Columbia.
Who was Russell Palmer?
Lt. Col. Russell Palmer obtained a
BA from UBC in 1926 and an MD
from McGill University in 1931, and
was serving with the Royal Canadian
Army Medical Corps in Kampen,
Netherlands, at the time of the libera-
tion. There he met by chance Dr Wil -
lem Kolff, a Dutch physician who had
been trying for some years to develop
a workable artificial kidney for pa -
tients with renal failure, something
which despite many attempts had not
been done successfully. After the Nazi
invasion of 1940, Dr Kolff joined the
Dutch resistance and was forced to
continue his work in secret and in
great danger, since some of his mate-
rial, metal derived from downed air-
craft, was wanted by the foe.
Palmer given blueprint ofKolff’s artificial kidneyWhen the Canadians arrived in 1945,
Dr Willem Kolff, anxious to discuss
his work with a physician from the lib-
erating forces, was introduced to Dr
Palmer who, as a general internist, had
no special interest in the kidney and
was unaware of attempts to create an
artificial one; there was no precedent
for a complex organ being replaced by
a machine. With the aid of an inter-

preter, Dr Palmer immediately saw
the significance of Dr Kolff’s work
and gratefully accepted the offer of a
“reprint” (i.e., blueprint) of his rotat-
ing drum artificial kidney ( ).
Dr Kolff had used his invention as
early as 1943 in a variety of patients
with renal failure but, despite techni-
cal success with the equipment, none
of the patients survived; later several
were shown to have had chronic ir -
reversible disease, and Dr Kolff con-

cluded that this treatment was only
indicated in those with the potential
for recovery.
The first patient whose life Dr Kolff
saved with his artificial kidney in Sep-
tember 1945 was a Nazi collaborator
imprisoned in the local barracks.2 She
was moribund from uremia due to
sulphonamide anuria following treat-
ment for cholecystitis and septicemia;
her kidneys recovered after treatment,
and she lived for a further 7 years.
First successfulhemodialysis with Kolff’s machineOn return to Canada with Dr Kolff’s
blueprint, Dr Palmer had the rotating
drum built by his brother, an engineer
on Granville Island. Palmer’s first
life-saving hemodialysis using this
equipment was carried out at Shaugh-
nessy Hospital in Vancouver in Sep-
tember 1947.3
In 1946 Dr Kolff gave copies of
his rotating drum artificial kidney to
England, the United States, and Cana-
da.2 It was used several times in Lon-
don in that year with indifferent results
and abandoned in favor of dietary
management. Dr MacLean in Montre-
al used it in 1948, as did the Ameri-
cans in the same year;4 hence Dr Palm -
er was the first to succeed with Dr
Kolff’s rotating drum in North Amer-
ica, and the fourth in the world, includ-
ing Kolff’s case mentioned above.
Soon after, the new UBC Medical
School opened in 1950. Dr Palmer was
named head of the Metabolic Unit at
Vancouver General Hospital (VGH)
for a short while with the rank of clin-
ical assistant professor of medicine.
Dr Palmer used the rotating drum
artificial kidney briefly at Shaugh-
nessy Hospital and thereafter at VGH
until 1957 with the assistance of Dr
Edwin Henry, a research fellow in
clinical investigation. In that time they
obtained 10 years’ experience of 54
patients with acute renal failure, 23 of
whom were dialyzed with the rotating
drum, 12 of whom survived.5,6
In 1956 Dr Henry left to work in
Prince George and was replaced at
VGH by Dr John D.E. Price. Mean-
while Dr Kolff, having immigrated to
the US to work at the Cleveland Clin-
ic in 1950, improved on his earlier
device and developed the twin coil
artificial kidney. Dr Palmer promptly
arranged for Dr Price to spend a few
weeks in Cleveland to learn about it.
On Dr Price’s return to the VGH, and
at Dr Kolff’s invitation, a trial of the
twin coil was carried out and its supe-
rior functioning reported by Drs Palm -
er and Price in 1957.7
The treatment of acute renal fail-
ure by hemodialysis was now estab-
lished, but up until 1960 a major prob-
lem was the need for repeated vascular
puncture, which inevitably damaged
vessels leading to lack of access; when
that occurred the only alternative was
peritoneal dialysis, or death. This prob-
lem of vascular access was the major
reason why hemodialysis for chronic
renal failure was not even considered.
Dr Gordon Murray, a surgeon in
Toronto unaware of Kolff’s work,
built a machine with which he did a
hemodialysis in December 1946. Al -
though it was successful, his machine
never came to anything for reasons
given in an excellent 1999 article enti-
tled, “Gordon Murray and the artifi-
cial kidney in Canada.”8 This extra or-
dinary man was named a companion
of the Order of Canada in 1967.
Dr Kolff was inducted into the
Inventors’ Hall of Fame in 1985, and
in 1990 was named by Life magazine
in its list of the 100 Most Important
Americans of the 20th Century.
Peritoneal dialysis Peritoneal dialysis also had problems
with access. Repeated puncture of the
peritoneal cavity carried the danger of
leakage, infection, and the potential
for visceral damage. Nevertheless Dr
Palmer’s interest in it began in the
1950s while still at VGH, in part be -
cause of these problems with hemo -
dialysis but also to relieve pressure on
this limited resource. Drs Palmer and
Henry published their experiences in
1963 using repeated peritoneal punc-
ture in eight acute and four chronic
renal failure patients; six of the acute
but none of the chronic patients sur-
vived, confirming the value of peri-
toneal dialysis in acute patients but
giving little hope for those with chron-
ic renal failure.9
In 1962 Dr Palmer left VGH to join
St. Paul’s Hospital, partly to pursue
his interest in peritoneal dialysis, while
Dr John Price continued to supervise
dialysis at VGH. In 1964 the Vancou-
ver General Hospital Renal Unit for
Dialysis was opened and thereafter
thrived and expanded under Dr Price’s
leadership. In those early days nephro -
logy was not recognized as a special-
ty, and it was not until 1979 that the
UBC Medical School created a formal
Division of Nephrology under Dr John
Dirks.
Back at St. Paul’s Dr Palmer, with
assistance from Dr C.E. (Ed) Mac-
Donnell, another internist with an in -
terest in the kidney, concentrated on
peritoneal dialysis. Although it had
been known that the peritoneal mem-
brane had clinical potential as long
ago as 1877, the first successful peri-
toneal dialysis for acute renal failure
did not take place until 1923. Reports
of successes thereafter were few until
the 1950s.10 A major reason for the
good guys
Palmer’s first life-saving hemodialysis
using this equipmentwas carried out at
Shaughnessy Hospitalin Vancouver in
September 1947.

catheter. This, like the shunts for hemo-
dialysis, remained in place for access
when needed and peritoneal dialysis
for chronic kidney failure also became
a reality.11
Back at St. Paul’s, Drs Palmer
and McDonnell put the new Palmer-
Quinton catheter to good use. There
were no hemodialysis facilities then at
St. Paul’s, and since younger patients
were given priority for the limited
resource at VGH, the two doctors
focused their attention on patients
over 50 years of age with chronic kid-
ney failure. In 1968 they reported their
experiences with peritoneal dialysis
using the Palmer-Quinton catheter in
21 patients, including a nurse aged 53,
who survived for just under 2 years,
did much of her peritoneal dialysis at
home, and returned to work part-time.
In effect she became the first recorded
patient with chronic renal failure to do
home peritoneal dialysis.12
However neither the shunt nor
the catheter were without problems.
The Scribner-Quinton shunts had the
propensity to clot, requiring declotting
by a physician or revascularization by
a surgeon.
The Palmer-Quinton peritoneal
catheter was prone to leaks, and in -
fection could enter the track of the
catheter through the abdominal wall
and cause peritonitis. However, both
devices paved the way for later im -
provements that are now in widespread
use. The Scribner-Quinton shunt was
superseded by the Cimino-Brescia
fis tula2,4 and the Palmer-Quinton
catheter by the Tenckhoff catheter,
whose Dacron cuffs fibrosed in the
abdominal wall, reducing the chance
of infection.4 There was now the dis-
tinct possibility of using both hemo -
dialysis and peritoneal dialysis for
long-term treatment of patients with
chronic renal failure.
New Renal Unit at St. Paul’s In 1968 Dr Palmer was instrumental
in recruiting his successor, the author,
from the trial home hemodialysis unit
funded by the State of Washington in
Spokane, a unit funded only for home
hemodialysis.13 Thus 4 years after the
opening of the Renal Unit for Dialysis
at VGH, a second such unit opened
at St. Paul’s, each now equipped for
hemo dialysis and peritoneal dialysis;
Dr Palmer was the driving force in the
inauguration of both.
That was the end of Dr Palmer’s
active involvement in dialysis but he
remained interested and in 1982 pro-
duced his acclaimed history of peri-
toneal dialysis.10 In 1992 he received
an award at the 12th Annual Confer-
ence on Peritoneal Dialysis in Seattle,
where he made a brief presentation,
“Afterthoughts”—essentially his swan-
song.14
What did Palmer achieve?Dr Russell Palmer introduced both
hemodialysis and peritoneal dialysis
to British Columbia and by initiating
the two renal units in Vancouver intro-
duced, if unwittingly, an essential ele-
ment of competition that triggered the
rapid expansion that has resulted in
BC’s leading position in this field.
The first patients to do home hemo -
dialysis were trained at St. Paul’s in
196915 and at VGH soon after. Home

sluggish advance was the danger of
repeated peritoneal puncture. Hence
although both hemodialysis and peri-
toneal dialysis often saved lives in the
short term, both had major problems
with the need for repeated access.
In the end both hemodialysis and peri-
toneal access problems were solved by
the use of Teflon and silicone rubber.
In 1960 Professor Belding Scrib-
ner of the University of Washington
in Seattle, a leader in long-term hemo -
dialysis, had, together with his engi-
neer Mr Wayne Quinton, devised Tef -
lon catheters that were inserted in an
artery and an adjacent vein for long-
term vascular access. These catheters
were joined by a flexible silicone
rubber tube so that with anticoagula-
tion blood could flow continuously
between hemodialysis treatments, the
tubes being uncoupled for the proce-
dure. Hence repeated vascular punc-
ture was avoided and the prospect of
long-term hemodialysis for chronic
renal failure became a possibility us -
ing this Scribner-Quinton shunt.2,4
Dr Palmer, alert to these advances,
saw the potential of silicone rubber
for use as a permanent peritoneal
catheter, and described his idea to Mr
Quinton, who fashioned the Palmer-
Quinton silicone rubber peritoneal

peritoneal dialysis was continued at
St. Paul’s16 and VGH was the first to
adopt continuous ambulatory peri-
toneal dialysis a major advance first
described in 1978.17
Several other cities in BC now
have dialysis units and train patients
to treat themselves at home; some
units were initiated and supported by
Dr John Price in the 1960s and others
later by St. Paul’s.
Several hundred patients in BC are
now dialyzing themselves independ-
ently at home; about 20% are doing
hemodialysis and the others periton -
eal.18 Hundreds more are dialyzing in
community centres with minimal assis-
tance from nurses. Well over 1000 are
receiving dialysis in hospital centres
and some in nursing homes because
they are elderly, infirm, or incapable
of learning the procedure.
The first renal transplant was done
at VGH in 1968, and when a second
team was warranted, St. Paul’s fol-
lowing in 1986. The advent of this sec-
ond team resulted in a surge in num-
bers and the transplant rate was tripled
in a few months. The total now trans-
planted approaches 4000. The paired
exchange program was started in BC
in 2009 and is increasing the pool of
eligible donors. The zenith of this
program to date is an exchange of kid-
neys among four couples.19
Is it too much to suggest that this
explosion of activity resulted from a
chance meeting in the Netherlands
65 years ago? I don’t think so. Histo-
ry is full of individuals who, marching
to the beat of their own drum, achieve
more than an army of conscripts to
another’s.
Dr Russell Palmer was better known
in the US than at home. In 1975 he
was elected to mastership of the Amer-
ican College of Physicians, an honor
granted only to “highly distinguished
physicians…who have achieved
recognition in medicine by…making
significant contributions to medical
science or the art of medicine…” Dr
Palmer qualified on both counts.
Dr Palmer was a modest man not
given to blowing his own trumpet.
Like most of those who together have
built our enviable renal failure pro-
gram, he was a member of clinical
faculty. Together with others in the
1940s and 1950s, and often opposed
by the academic and political estab-
lishment,20,21 he saw and seized on
possibilities that in the aggregate have
resulted in the well-being of millions
worldwide whose lives have been
saved and improved beyond measure
by dialysis while they await the ulti-
mate goal of a functioning kidney
transplant.
In the last paragraph of his swan-
song, “Afterthoughts,” Dr Palmer
reminds us that however necessary
and indeed seductive discovery can
be, it is of no value in the context of
our profession unless it serves our
main purpose to care for the sick and
injured.14

The Divisions of Family Practice
initiative is clearly meeting the
needs of family physicians
across the province. Since its launch
almost 2 years ago, the initiative has
seen the creation of 18 divisions, rep-
resenting the interests of physicians in
68 communities. By year-end another
two divisions are expected to be added
to the total.
Although many of the issues being
addressed through the Divisions of
Family Practice—such as expanding
capacity for primary care and enabling
access to a family physician for all
British Columbians—are similar
across the province, the divisions also
focus on identifying and addressing
specific local community needs.
“Our Division gives us an oppor-
tunity to make positive changes in our
community,” says Dr Steve Larigakis,
physician lead for the White Rock–
South Surrey Division. “In the past
there wasn’t a mechanism for improv-
ing things. Now we can identify local
problems and through our Collabora-
tive Services Committee we can work
together toward solutions.”
One of the current priorities for the
White Rock–South Surrey Division is
the Attachment initiative, also called
“A GP for Me,” which is funded by the
General Practice Services Committee
(GPSC). The provincial goal for this
program is to ensure by 2015 that
every British Columbian who wants
access to a family physician has it.
“The solution to attachment is
multi-faceted,” says Dr Brenda Hef-
ford, lead physician for the Division’s
A GP for Me initiative. “It involves
helping family physicians in the work
they do, while also increasing com-
munity capacity.”
To expand capacity, the White
Rock–South Surrey Division is devel-
oping a recruitment strategy for attract-
ing new general practitioners to the
community, and hopes to recruit up to
four new family physicians within the
next 2 years.
The Division is also working with
Fraser Health to develop a multidisci-
plinary primary care access clinic,
slated for opening in early November,
to provide a “primary care transition-
al home” for local patients discharged
from hospital or emergency who do
not have a family physician. The
Division is providing operational sup-
port for the clinic, which will be staf -
fed by a community physician and by
nurse practitioners provided by Fras-
er Health.
Recruitment of new physicians
has also been a priority for the Abbots-
ford Division of Family Practice,
which in the past year has succeeded
in attracting seven new family physi-
cians to the community.
“We discovered that in the past
there were doctors making inquiries
about working here, but since recruit-
ment was handled by the health au -
thority and not locally, there wouldn’t
be any follow-up,” says Dr Holden
Chow, physician lead for the Division.
By hiring a coordinator and partner-
ing with Fraser Health and adminis-
trators at Abbotsford Regional Hospi-
tal, the Division was able to ensure
that every physician expressing inter-
est in moving to the region was con-
tacted and encouraged to choose
Abbotsford. The Division has a goal
of securing three additional GPs and
is currently in discussions with four
potential recruits.
Many of Abbotsford’s newly re -
cruit ed physicians have requested
hospital privileges and are participat-
ing in the Division’s Hospital Care
Physician Program.
“On any given day up to 15 admis-
sions to the hospital are unattached
patients who would be uncared for if
we didn’t have this program,” says Dr
Chow. The new physicians have revi-
talized the hospital care program and
helped reduce the stress for other
family physicians with hospital privi-
leges, says Dr Chow.
In Prince George, an in-patient
primary care program has been devel-
oped to support family physicians and
patients in hospital who don’t have
their own doctor, says Dr Garry Knoll,

physician lead for the Prince
George Division. There is also an
unattached patient clinic to follow
up with these patients once they
are discharged from hospital.
Dr Knoll says the Division has
discussed partnering with North-
ern Health to provide a home for
up to 5000 unattached patients in
the community, many of whom
have special needs. By providing
primary care along with a multi-
disciplinary range of services in
areas such as social work, physio-
therapy, and mental health and
addictions counseling, Dr Knoll
says the needs of up to 30% of
Prince George’s unattached patients
could be met.
This summer the Chilliwack
Di vision of Family Practice launch -
ed a hospital care program. Ac -
cording to physician lead, Dr Scott
Markey, the program is working
out better than anticipated.
“We have had some success in
bringing back physicians who had
stopped working at the hospital,
and with some locum physicians
in the community who have cho-
sen to keep up their hospital skills
by working in the program,” says
Dr Markey.
Overall, among the divisions
there is a strong feeling of opti-
mism about the chance to make
local changes toward improving
primary care.
“It’s pretty exciting times for
family practice right now,” says
Dr Hefford. “The things going on
in the divisions have opened doors
and opportunities that didn’t exist
before.”
“There’s a recognition now that
family practice is where things can
be done to make a difference,”
says Dr Chow. “We’ve heard that
from all levels and now we’re
starting to see it.”

New BC-wide surgerybooking systemAfter 3 years of use, the Clinical
Assessment Tool has now been dis-
continued and replaced with a stan-
dard province-wide, diagnosis-based
prioritization system for all adult and
pediatric elective surgeries in BC (see
the ). As of 1 December 2010
three additional fields will be added
to all Health Authority OR booking
forms—two of those fields will be for
“Date of Decision for Surgery” and
“Cancer Status” and the third will be
mandatory completion of a “Condition/
Diagnostic code” field. More than 120
surgical leaders across the province
representing 14 surgical reference
groups and subspecialties provided
feedback on the development of a
comprehensive list of adult patient
condition/diagnosis codes.
The new system is designed to be
much simpler to use. Surgeons will
select the relevant patient condition/
diagnosis code from the list provided
by their health authority and enter it
on their existing OR booking form,
rather than filling in a separate form.
These codes link every patient’s diag-
nosis and clinical condition to one of
five priority levels and an associated
maximum wait time target.
Because these changes are being
incorporated into your health authori-
ty’s OR booking form, there will be
no fee attached for completing it.
Benefits for surgeonsBecause there is now an objective and
standardized methodology for desig-
nating patient diagnosis/condition
descriptions to a priority level, sur-
geons will be able to review their wait
listed patients by level of urgency and
see how long their patients have been
waiting relative to the maximum rec-
ommended target. The elimination of
the Clinical Assessment Tool means

CKD increases the normal risk of car-
diac morbidity by 10 times. Fully 40%
of patients on dialysis also have dia-
betes.
The ability of GPs to manage care
for patients with chronic conditions
often depends on effective communi-
cation and exchange of knowledge
with specialist colleagues. The BCMA
and Ministry of Health Services have
highlighted the importance of effec-
tive physician-to-physician commu-
nication through recent updates to fee
schedules that facilitate inter-provider
contact. Strategic alignment of com-
pensation with point-of-care health
care processes provides appropriate
in centives to enhance interaction
among participating physicians and
represents a philosophical shift toward
a shared care model.1
Shared care refers to a set of ideas
designed to facilitate collaboration
between GPs and specialists. The ben-
efits are thought to include reduced
patient wait times for specialist care
by minimizing the amount of primary
care provided by specialists, a de crease
in inappropriate consultations, less
duplication of testing and fewer un -
necessary prescriptions, and increased
communication and knowledge ex -
change between specialists and GPs.
Shared care also seeks to open
ongoing dialogue between specialists
and GPs to more effectively define
roles and mutual expectations and en -
sure that patients do not “fall through
the cracks.”
In support of shared care, the Bri -
tish Columbia Provincial Renal Agency
(BCPRA) has developed a program
to engage GPs and neph rologists to -
ward improving care for patients with
kidney disease. Within this program,
one initiative has focused on studying
stroke certification courses. The 10-
article special section is free for health
care providers, first responders, and
individuals who want to be prepared
to provide emergency care.
Titles include “Recognizing the
Signs of Stroke,” “Trends in Stroke,”
“Common Stroke Risk Factors,” “Dif-
ferentiating Stroke from Mimics,” and
“The Seven D’s of Stroke Survival.”
Health Education Solutions pro-
vides the cognitive portions of each
American Heart Association (AHA)
course, including Acute Stroke, Stroke
Prehospital Care, and Stroke Hospi-
tal-based Care, entirely online. The
courses’ web-based, self-paced mod-
ules provide a flexible training option
for health care providers. Students who
follow the online course are re quir ed
to meet with an AHA instructor to
complete a hands-on skills practice
session and test.

BC Genome SciencesCentre advancesIn 1997, Nobel laureate Dr Michael
Smith created Canada’s first genomic
research centre dedicated to the study
of cancer in British Columbia.
At the time, genomics was still in
development—it would be another 3
years before scientists decoded the
human genome. British Columbians
invested $24 million through the BC
Cancer Foundation to establish Cana-
da’s Michael Smith Genome Sciences
Centre at the BC Cancer Agency.
Now one of the largest genome
centres in the world, the centre has
announced four major research break-
throughs in the past year revealing
specific genetic mutations underlying
the cause or development of cancers.
All these breakthroughs were made
possible by next-generation computer
sequencing technology, which has
the capacity to process and analyze
torrents of data at previously unimag-
inable rates and at a fraction of the
original cost.
Ten years ago, sifting through the
human DNA code to find individual
genetic mutations was the proverbial
hunt for the needle in a haystack. Up
until about 2 years ago, researchers
had no way to look through thousands
of kilometres of DNA in each of an
individual’s trillions of cells.
The Genome Sciences Centre’s
technology platform provides BC
Can cer Agency researchers with very
specific biological targets at which to
aim new treatments to improve pa -
tients’ outcomes. Now, personalized
medicine—once a distant possibility
—is within researchers’ grasp.
This was demonstrated by the
Centre’s latest breakthrough, recently
published in Genome Biology. Centre
director Dr Marco Marra and his team
sequenced the genome of a living
patient’s tumor for the first time,
which guided oncologists to a treat-
ment regime for his rare and aggres-
sive cancer. It worked—the cancer
was halted for several months.
Although there are many chal-
lenges to overcome before this type of
approach becomes routine, in the near
future researchers will be able to look
at tumors at the genetic level to deter-
mine whether it is possible to tailor a
patient’s treatment and ultimately
improve that patient’s outcome.

at providing opportunities for GPs to

These initiatives are timely in view
of the epidemic prevalence of CKD,
which is estimated to affect more than
2 million Canadians.2 The shows

British Columbians live with high-
risk CKD stage 3 to 4. At the same
time, BC has only about 50 full-time
nephrologists. It is clear that provi-
sion of effective early CKD care by
primary care physicians is needed to
optimize outcomes for these patients.
To help GPs manage the increas-
ing number of CKD patients in their
practices, the BCPRA has developed

tives derived from a formal survey of
GP’s educational needs. The first

A sbestos is a fibrous silicate
mineral with numerous desir-
able characteristics, such as
resistance to heat and chemicals, good
tensile strength, and flexibility. As a
result, it has been used in thousands of
products, including insulation (acous -
tic, heat, electrical), friction material
(brake pads), gaskets, concrete rein-
forcement (pipes, sheeting, tiles),
plaster compounds, and spackling. In
the past 40 years, as adverse health
effects were recognized, the use of
asbestos in Canada has been marked-
ly curtailed. Despite this, the inci-
dence of asbestos-related diseases has
not declined, because of the long
latency characteristic of these diseases
and the ubiquity of materials contain-
ing asbestos.
Asbestos can cause a variety of
pulmonary diseases, some generally
benign pleural changes, such as effu-
sion, plaques, calcification, and hy -
pertrophy, and some more pernicious,
such as asbestosis, bronchogenic car-
cinoma, and malignant mesothelioma.
Diagnosis of asbestosisAsbestosis is a diffuse interstitial fi -
brosis of the lung parenchyma caused
by prolonged repeated exposure to
high levels of asbestos fibres. The
fibrosis typically starts symmetrically
at the lung bases and, as the disease
progresses, can extend to all lung
fields, producing stiffer lungs and
reduced gas exchange ability. Advanc -
ed asbestosis can be debilitating, as
severe fibrosis can lead to pulmonary
hypertension and right-sided heart
failure.
Asbestosis typically has a long
latency period, with symptoms occur-
ring 20 years after the onset of expo-
sure. The severity and progression of
the disease is dose dependent. Among
workers with high cumulative lifetime
exposure, the disease can continue to
progress even with cessation of expo-
sure.
Initially, workers with asbestosis
complain of shortness of breath with
exertion and decreased exercise toler-
ance. A dry cough can develop and
rales can be heard at the lung bases. As
the disease progresses, dyspnea oc -
curs at rest and there may be clubbing,
cyanosis, and signs of right-sided
heart failure.
Lung function tests demonstrate a
restrictive pattern with reduced FVC,
lung volumes, lung compliance, and
diffusion capacity. Asbestos by itself
does not typically result in small air-
way disease or COPD, so obstructive
changes on lung function testing are
uncharacteristic. Oxygen saturation
can decline with exercise or, in more
severe cases, at rest. Small irregular
opacities are noted on chest X-rays.
Coincidental radiologic manifesta-
tions of asbestos-related pleural dis-
ease may be found.
Since asbestosis affects only the
lungs, this is one way to differentiate
it from other systemic diseases that
also cause pulmonary fibrosis. Differ-
entiating asbestosis from idiopathic
pulmonary fibrosis can be challeng-
ing. The presence of asbestos-related
pleural changes is very useful as a
marker of asbestos exposure. Howev-
er, the most essential diagnostic crite-
rion is a history of prolonged and
repeated exposure to asbestos. The
risk of developing asbestosis is low if
the cumulative exposure is less than
25 fibres/ml-years (the metric fibres/
ml-years is analogous to pack-years
for cigarette smokers).
Those at greatest risk for asbesto-
sis are individuals who were actively
working with asbestos in the past. In
British Columbia, this includes work-
ers generally older than 60 who were
employed prior to the early 1980s as
asbestos miners and millers, construc-
tion workers, insulators, pipefitters,
millwrights, naval yard workers,
power or chemical plant workers, or
ship or train mechanics. Today, these
types of workers are still at risk,
although the risk is mitigated by im -
proved work practices that reduce
exposure. Other workers at risk for
asbestos-related diseases are those
involved in asbestos abatement, older
building renovation and demolition,
or building maintenance. The risk,
however, is generally low because, in
most circumstances, the presence of
asbestos is recognized and exposure is
controlled.
Treatment and preventionSince there aren’t any good treatments
for asbestosis, the best approach is
disease prevention. The prevention
branch of WorkSafeBC has been
actively involved through worker and
employer education, workplace in -
spections, and overseeing abatement
procedures. WorkSafeBC requires
em ployers to maintain an asbestos
inventory identifying all locations
where asbestos is found and to control
access to those areas.
Physicians can participate in pre-
venting asbestosis by identifying pa -
tients at risk with a comprehensive
occupational history, and referring
suspected cases to WorkSafeBC. If
inappropriate workplace exposure is
suspected, please contact WorkSafe -
BC’s prevention branch at 1 888 621-
7233.

Impairment-related crashes are the
leading criminal cause of death in
Canada, accounting for approx-
imately 1239 deaths, 73 120 injuries,
and as much as $12.6 billion in finan-
cial and social costs annually.1 Sanc-
tions resulting from conviction are
effective in preventing impaired driv-
ing.2-6 However, the injured impaired
drivers treated in our emergency de -
partments are infrequently convicted
of impaired driving. Three Canadian
studies have been published. The
first found that only 11% of injured
alcohol-impaired drivers identified in
the British Columbia trauma registry
between 1992 and 2000 were convict-
ed of impaired driving.7 The second
study found that the conviction rate
for injured alcohol-impaired drivers
admitted to Calgary Health Region
trauma service between 1999 and
2003 was only 16%.8 The third study
reported a conviction rate of only
6.7% for all alcohol-impaired drivers
injured in a crash who presented to a
tertiary care emergency department in
British Columbia from 1999 to 2003.9
Follow-up over a 4 1/2 year period
indicated that 30.7% of the injured
impaired drivers were engaged in sub-
sequent impaired driving, notwith-
standing that they injured or killed
someone in more than 84% of initial
crashes.9 These studies suggest that
our emergency departments may have
become safe havens for the worst
drinking drivers, those drivers who
are involved in fatal or personal injury
crashes.
Three separate Criminal Code,
R.S.C. 1985, c. C-46, provisions allow
the police to demand or seize blood
samples from suspected impaired
drivers. First, under section 254(3)(b),
the police may demand blood samples
from a person if they have reasonable
grounds to believe (a) that he or she
committed an impaired driving offence
within the preceding three hours; and
(b) that, by reason of the person’s
physical condition, he or she is inca-
pable of providing a breath sample or
it is impracticable to obtain one. Sec-
ond, under section 256, the police may
apply to a justice for a warrant auth -
orizing them to seek blood samples
from a driver if they have reasonable
grounds to believe that (a) the driver
committed an impaired driving
offence within the previous 4 hours;
(b) the driver was involved in a crash
resulting in death or bodily harm; and
(c) a medical practitioner is of the
opinion that the driver is unable to
consent to the drawing of blood sam-
ples, and that the taking of the samples
would not endanger the driver. Third,
under section 487 of the Criminal
Code, the police may apply to a justice
for a general search warrant authoriz-
ing them to search for and seize any
relevant evidence, including blood
samples that have already been taken
from a suspected impaired driver for
treatment purposes. Before issuing
such a warrant, the justice must be sat-
isfied, based on information sworn
under oath, that there were reasonable
grounds to believe that such blood
sample evidence would be found on
the premises.
To satisfy these Criminal Code
provisions the police must establish
that they had “reasonable grounds to
believe that the driver committed an
impaired driving offence.” However,
in many cases the police will need
information about the suspect’s phys-
ical condition that can only be ob -

tained from the suspect’s physician.
For example in R. v. Clark, the accused
was involved in a head-on collision
that killed another driver. Gerein com-
mented that the sweet odor on the
accused’s breath may potentially have
been due to alcohol. However, the
police officer did not provide reason-
able grounds to obtain a blood sam-
ple, because the odor may have been
due to another source such as dia-
betes.10 The police officer could only
have determined if the patient had
diabetes by interviewing Mr Clark’s
physician.
However, health professionals
who release patient information with-
out consent or statutory authority
would be in breach of their common
law, professional, and statutory confi-
dentiality obligations. The Canadian
Medical Association Code of Ethics
permits “disclosure of patients’ per-
sonal health information to third par-
ties only with their consent, or as pro-
vided for by law, such as when the
maintenance of confidentiality would
result in a significant risk of substan-
tial harm to others or, in the case of
incompetent patients, to the patients

consent or statutoryauthority would be in

statutory confidentialityobligations.

ple results were excluded, and the
charges against the accused for im -
paired driving causing death and im -
paired driving causing bodily harm
were dismissed.14
Complicating the issue further, the
present statutes require the collection
of evidentiary samples within 3 hours
of the impaired driving offence. Often
the police cannot establish grounds
for demanding these evidentiary
blood samples within this time. In
other comparable democracies, blood
samples are taken when the patient
enters the emergency department and
are held in a secure location within
the hospital until the police have in -
dependently established grounds for
their seizure.13
Moreover, the Criminal Code
effectively limits the taking of blood
samples in hospitals, where drawing
blood is routine and taking eviden-
tiary breath samples is simply not fea-
sible due to limited space and patient
care priorities. Before being allowed
to demand a blood sample, the police
must demonstrate that the patient is
unable to provide a breath sample due
to their physical condition or that it
is impracticable to do so. The courts
have generally held that police should
not make decisions about the driver’s
inability to provide a breath sample
unless they have consulted a medical
professional.13 For instance, in R. v.Brooke, the accused was wearing a
neck brace and strapped down at the
time of arrest. The officer demanded a
blood sample, but the court excluded
the blood sample evidence because
the officer had not specifically asked
the attending physician about the ac -
cused’s physical condition and whether
he was able to provide a breath sam-
ple.15 Thus, in most cases, police can-
not obtain evidentiary breath samples
for logistical reasons, and a physician
cannot give them the information they
require to demand blood samples with-
out violating his or her confidentiality
obligations.
Thus, the legal “catch-22.” The
police need a considerable amount of
information to comply with the legal
requirements for a blood sample de -
mand from a patient who is hospital-
ized. It is very difficult for the police
to independently gather this informa-
tion, given that the patient may be
lying on a stretcher or otherwise
unable to perform a standard field
sobriety test. Moreover, the courts
have indicated that tests on approved
screening devices may only be con-
ducted at roadside. Therefore, in the
vast majority of cases, the police will
only have authority to demand an evi-
dentiary blood sample if they obtain
the necessary information from the
patient’s physician. However, the phy -
sician cannot provide this information
to police without violating his or her
confidentiality obligations. Such a
breach of confidentiality will likely
result in the evidence being excluded
and the accused being acquitted.
The Canadian Medical Associa-
tion is also concerned about this issue.
In 2008, the CMA passed the follow-
ing resolution at General Council:
“The Canadian Medical Association
urges the federal Department of Jus-
tice to conduct a review of the appli-
cable sections of the Criminal Code
related to blood testing of intoxicated
drivers who are treated in hospital
following a motor vehicle crash.” The
authors of this paper are of the opinion
that the following four amendments
would improve the effectiveness of
these Criminal Code provisions.
1) The Criminal Code should be
amend ed to authorize police to
demand blood samples from any
hospitalized occupant of a motor
vehicle that has been involved in a
fatal or personal injury crash. The
evidentiary collection process could
be modeled after the systems that
have been in place in England, New
Zealand, and Australia for many
years.13
2) To facilitate the timely collection of
evidentiary blood samples, they
should be taken from all occupants
themselves.”11 The Canadian Medical
Protective Association advises: “While
physicians may have a desire to col-
laborate with police to foster public
safety and injury prevention, physi-
cians are bound by a duty of confi-
dentiality to their patients. As such,
physicians should not provide any
patient information to the police
unless the patient has consented to this
disclosure or where it is required by
law.”12 While section 257(2) of the
Criminal Code protects medical prac-
titioners from criminal and civil lia-
bility for taking a blood sample pur-
suant to a valid demand or search
warrant, it does not protect them from
liability for breaching confidentiality
in assisting police to make a valid
demand or obtain a search warrant.
If the police wrongfully obtained
confidential patient information, a
blood sample demand made or a war-
rant obtained based on this informa-
tion would be invalid. Any subsequent
seizure of the blood sample would be
found to violate section 8 of the Char-
ter and, depending on the specific
facts, may well be excluded at trial.13
For example, in R. v. Dersch, the
accused expressly refused a police
demand for blood samples and told
the doctor not to draw blood in any
circumstances. However, once the
sus pect was unconscious, the doctor
took blood samples for medical pur-
poses. At an officer’s request, the doc-
tor disclosed the accused’s BAC to the
police, who subsequently obtained a
warrant and seized the samples. The
Supreme Court of Canada held that
the samples should not have been
taken without the accused’s consent,
and that the doctor breached his con-
fidentiality obligation in disclosing
the accused’s BAC to the police, as
the police had not used appropriate
means to obtain this information. The
Court held that the police conduct in
obtaining the suspect’s BAC informa-
tion was analogous to a search and
seizure. Consequently, the blood sam-
cohp

of motor vehicles involved in
fatal or personal injury crashes
upon their entry into the hos-
pital. These samples should be
stored in a secure location and
only released if the police can
independently establish grounds
for their seizure.
3) The Criminal Code and all laws
governing patient confidentiali-
ty should specify what informa-
tion physicians must provide to
the police during an impaired
driving investigation. The police
cannot effectively investigate
impaired driving cases unless
they have been told that the
patient has been admitted to hos-
pital, the patient’s location, if the
patient can be interviewed, and
if drawing blood would endan-
ger the patient.
4) The Criminal Code should be
amended to remove the “prefer-
ence” for breath samples when
suspected impaired drivers are
taken to hospital.

Make a difference in your communityDivisions of Family Practice, an initiative of the General Practice Services Committee, are community-based affiliations of family physicians working together to improve patient care, to increase family physicians’ influence on health care delivery and policy, and to provide professional satisfaction for physicians.
The first of its kind in Canada, the Divisions initiative provides physicians with a stronger collective voice in their community while supporting them to improve their clinical practices and offer comprehensive patient services. The initiative is founded in the belief that our communities are best served when we seek to improve the health of all residents in the region.
Being a member of a Division offers a number of benefits, such as:
services around a Division practice area
and wellness programs
We invite you to join your local Division and make a difference in the delivery of primary health care in your community. www.divisionsbc.ca
