Application exampleThekneejointsimulationisusedtomeasurethekinematicsofsquattingpre- andpost-unicondylar kneearthroplasty.
The knee joint simulator allows to measurethe mechanical behaviour of the knee duringseveral motor tasks before and after asurgical procedure. Effects of differentparameters (implant design, alignment, jointbalancing, surgical mistakes) can thus beisolated and assessed within the samespecimen. The system applies forces to thetendons and the knee is guided solely by theanatomy of the specimen’s joint, moreaccurately replicating loaded, in vivoconditions, compared to commerciallyavailable robotic systems.
