Orthopedic Surgical Procedure

A. Definition

- Is the medical specialty that includes the investigation, preservation and

restoration of the form and function of the extremities, spine and

associated structures by the medical, surgical and physical methods.

B. Classification

Shoulder

I. Shoulder Arthroplasty

- Is a surgical procedure for restoring motion to a stiffed joint as well as the

necessary stability of the joint and eliminate joint pain.

3 Basic types of Arthroplasty

a. Replacement arthroplasty

- One or both joints are replaced by prosthesis, usually metal, plastic or the

most frequently used, a combination of both.

b. Interpositional arthroplasty

- It involves insertion of a substance such as fascia, skin, plastic, or metal

between the 2 joint surface.

c. Excision arthroplasty

- Removal of a periarticular bone from one or both joint surface leaving a

gap of 2 cm

Indications

- Intractable pain at rest or in motion associated with RA or DJD

- Severe loss of UE strength and function

- Decreased ROM

Contraindications

- Active infection

- Patients with neuropathic joints

- Young heavy laborers who are unwilling to change their lifestyle


2/23

Complications

- Proximal migration of the humeral component

- Infection

- Instability

PT management

- Operated shoulder is immobilized with the arm in a sling positioned in

adduction, IR and slight forward flexion of 10-20 degrees

Maximum protection phase

Duration: 1-3 weeks

a. Maintain normal motion and to minimize muscle guarding and spasm,

relax and gently massage the neck, shoulder and scapula.

b. To maintain normal hand, wrist and elbow function, begin active exercises

to these areas immediately after surgery

c. Continous Passive Motion to the shoulder

d. Gentle Pendulum Exercise without weights

e. Passive and AAROM emphasizing flexion, scaption, abduction to 90 with

arm IR and elbow flex

Moderate Protection Phase

Duration: 2-6 weeks post op

a. To regain control of shoulder girdle muscles, progress from AAROM to

active shoulder motions

b. To increase strength, isometric exercise against minimal resistance

Minimum Protection Phase

Duration: 4-6 weeks post op

a. To strengthen shoulder girdle, begin PRE using therabands or hand held

weights emphasizing on low loads and high repititons

13/23

- Deformity of toes, foot or ankle

- Patients with high functional demands and pain free compensatory

movements in adjacent joints

Post Op Management

- The fused joints are immobilized in plaster of skeletal pins for 6-12 weeks.

Patient must be non weight bearing. Gait training with assistive is

necessary. To maintain mobility, AROM is performed. Patient is advised of

proper shoe selection.

III. Common Ligament tears

- A third degree sprain of the lateral ankle, which occurs as a result o

severe inversion sprain, often causes complte tears of the anteriortalofibular and calcaneofibular ligaments. A complete tear of one or more

ligaments can cause marked instability and impaired functional activities

of an individual

- Maintain strength of the hip and knee on the affected side


- Begin mobilization of the restricted joint and low intensity muscle

stretching

- Increase strength of the ankle in open chain multiple angle, isotonic

resistance exercises against elastic tubing

- Apply rhythmic stabilization exercises to improve balance and stability of

the LE

- Add functional activities like jogging, toe walking and pylometrics

- Patient return to full activity by 6-9 weeks


15/23

Total Hip Replacement

I. Definition

- Is the most effective method of relieving pain and restoring movement in

hip affectation. This involves the replacement, by surgical mean, of a

severely damaged hip joint with an artificial one usually the acetabular

cartilage by a high molecular weight, high density polyethylene socket

and the femoral head by a metallic prosthesis

II. Epidemiology

- Is a relatively common procedure, with an estimated of 75,000 THRs

performed on 65,000 patients annually in the US. About 65% of the

procedures are performed on patients over 65 yrs old, with another 25%

performed on patients between 55-64 yrs old.

III. Etiology

Indications

- Severe hip pain with motion and weight bearing as a result of joint

deterioration and loss of articular cartilage associated with RA, OA, AS and

AVN

- Marked limitation of hip motion

- Instability or deformity of the hip

- Failure of previous hip surgery

IV. Complications

Local

- Deep Infections

- Dislocations


16/23

- Heterotrophic bone formation

- Fracture of he femur

- Perforation of the femur or acetabulum

- Vascular complications

Systemic

- Death

- Thromboembolic disease

- Urological complications

- Pulmonary, cardiovascular and GI complications

V. Prognosis

- THR, when done for incapacitating pain and dysfunction gives a

predictably excellent result. Relief of pain and return to useful function

can be expected. The usual patient can become independent within 3

months. Acetabular loosening may occur in 10% of the patients by the

tenth yr, and probably increase with time.

VI. Medical Management

PT Assessment

I. Assessment

- Determine the amount and type of pain, swelling or crepitation the patient

is experiencing

- Measure the AROM and PROM of the involved extremity

- Check the ROM of all the other joints

- Grade the strength of the affected extremity

- Estimate he strength of the affected joints or extremities as a basis for

post operative ambulation, transfers and ADLs


17/23

- Determine the level of functional independence that the patient had pre

op and the level that he expects post operatively

- Evaluate the gait characteristics, type of assistive device and degree of

weight bearing used during ambulation

II. Treatment and rationale of Management

1. Immobilization

- After surgery when patient is lying in the bed in the supine position, the

operated limb must remain in the position of slight abduction and neutral

rotation.

2. Exercise


- Deep Breathing, coughing and ankle pumping immediately to prevent

pulmonary and vascular complications

- Initiate ROM and resisted exercises ASAP to maintain strength and

flexibility of the un operated lower limb and UE

- Begin low intensity, pain free isometrics against gentle resistance to

prevent atrophy of the operated limb

- Begin gentle distal to proximal massage of the operated limb to decreasepost op edema of soft tissues and to decrease hypersensitivity and post

op pain

- Begin AROM or AAROM of the operated hip within a protected range while

the patient is lying supine to maintain soft tissue and joint mobility

- To ensure that bed mobility and transfers are performed safely, review

these techniques to the patient

- When patient is allowed out of bed, usually 2-3 days post op, begin the

following activities:

Short periods of sitting at edge of bed with hips in no more then 45

degrees of flexion and hips slightly abducted

Gait training in parallel bars with walker or crutches with PWB on

operated side



18/23

- Avoid vigorous stretching but promote heel extension and prevent hip

flexion contracture by having the patient lie prone as tolerated

- If the prosthetic components have been cemented in place and no

trochanteric osteotomy was necessary, exercises in weight bearing, when

tolerated can progress rapidly.

- If trochanteric osteotomy was performed, weight bearing and progression

of exercises will be significantly restricted for at least 6-8 weeks to allow

trochanter to heal

With these considerations in mind,during the period of moderate protection:

- Progress AROM gradually in a protected range, avoid hip flexion past 90

degrees and adduction past neutral

- Emphasize the development of neuromuscular control of hip musculature

rather that strength by means of active and light resisted motionsperformed repitively

- Perform movements in an open close kinematic chain. Have the patient

maintain PWB on the operated leg by performing closed chain exercises

standing in the parallel bars or while using walker

Minimal Protection Phase

- Emphasize closed and open chain strengthening and improving endurance

in the hip extensors and abductors when safe

- Use lightweights and high repetitions in a PRE program

- Have the patient make a transition from walker or crutches to cane. May

occur as late as 12 weeks post op

- To improve muscular endurance and general conditioning, have the

patient exercise on a stationary bicycle. Raise the height of the bicycle to

prevent excessive hip flexion

- Avoid high impact recreational activities, such as jumping or restricted

movements that impose heavy rotational forces on the limb

Total Knee Replacement

I. Definition

- Is a surgical procedure in which injured or damaged par of the knee joint

are replaced with artificial parts. The new knee will consist of a metal shell


19/23

on the end of he femur, a metal and plastic trough on the tibia, and if

needed a plastic button in the knee cap.

II. Epidemiology

- TKRs are usually performed in people suffering from severe arthritic

conditions. Most patients who have artificial knees are over the age 55.

Highest rates of utilization were found in Northwest and Midwest, and

lowest were in the East and South. Approximately 65% are females.

III. Etiology

- Severe joint pain with weight bearing or motion that compromises

functional abilities

- Extensive destruction of articular cartilage of the knee due to arthritis

- Gross instability or LOM

- Marked deformity of the knee such as genu varum or valgum

- Failure of a previous surgical procedure

- Significant stiffness

IV. Classifications

Unconstrained Prosthesis

- Can be unicondylar, bicondylar or total condylar

- Can be cruciate retraining, where PCL is spared

- Can be cruciate excising if PCL is no intact

Constrained Prosthesis

- Are hinged or allow no significant accessory motion of the knee, or

partially articulated, semiconstrained replacements that allow a small

degree of varus, valgus or rotation are rarely used today

- Indicated only for patients with severe instability and deformity of the

knee


20/23

V. Complications

- Knee pain

- Loosening of prosthesis

- Stiffness

- Metals and plastics may increase risk of infection

- Breakage of components

- Pneumonia, bed sores and confusion

VI. Prognosis

- Almost all patients who undergo TKR report a significant relief of pain withknee motion and weight bearing. Although patients are encouraged to

achieve full functional ROM of the knee by the time of discharge after

surgery. It may take at least 3 months post op for patients to regain

strength in the quadriceps and hamstring to a pre operative level. About

85-90 of TKR are successful up to ten years. The major long term problem

is loosening. By ten years, possibly 25% of TKE may look loose on xray.

PT Management

I. Assessment

- Determine the amount of pain the patient is experiencing

- Measure the AROM and PROM of the involved extremity

- Check the ROM of all the other joints

- Grade the strength of the affected extremity

- Estimate he strength of the affected joints or extremities as a basis for

post operative ambulation, transfers and ADLs

- Determine the level of functional independence that the patient had pre

op and the level that he expects post operatively

- Evaluate the gait characteristics, type of assistive device and degree of

weight bearing used during ambulation

II. Treatment and Rationale of Management



21/23

- Quads and Hams setting exercise, passively coupled with neuromuscular

ES; SLR in supine, prone and sidelying positions to regain neuromuscular

control of the hip and knee musculature while knee is immobilized

- Ankle pumping exercises immediately after surgery ; gentle distal to

proximal massage of the operated LE ; CPM to promote circulation anddecrease post op edema and pain

Weight Bearing

1. Biological Fixation

- Is restricted up to 6 weeks post op and gradually progress over the

duration of rehabilitation. Full weight bearing and ambulation without

assistive devices may not be permissible for up to 12 weeks post op

2. Cement Fixation

- Weight bearing as tolerated is permissible immediately after surgery and

increase to full weight bearing over 6 weeks. Patient should continue to

use crutches or cane through moderate and minimum protection phase of

rehabilitation until adequate strength and stability have returned o the

operated LE.


- Exercises to increase strength

Multiple angle isometrics and light isotonic resistance exercises

of the quads and hams can be added

Resisted SLR in various positions should be included to increase

strength of hip musculature

As weigh bearing permits, closed chain mini squats and short

arc lunges to improve stability and functional control of knees

- Exercises to increase ROM

Gentle self stretching or contract relax exercises are also added

to continue to increase ROM if limited motion persist

When using a stationary bicycle, the patient may first have the

seat positioned as high as possible

To increase knee flexion, the seat can be gradually lowered

Minimum Protection and return to activity phase


22/23

- By the 12th week after surgery, the emphasis on rehab is on muscle

conditioning so that the patient will have the strength and endurance to

return to full functional activites

- Ambulation activities, stair climbing and so on are gradually increased

- Stationary bicycling and aquatic exercise are excellent non impact

conditioning activites

III. Home and Bedside Instructions

- Positioning to prevent contractures

- AROM t o adjacent joints to maintain ROM

- Ankle pumping exercise to promote circulation

- Relaxation exercises
