A Total Knee Replacement Model for Evaluation of Joint Mechanics

Abstract

The success of current total knee replacement (TKR) devices is contingent on the kinematics and contact mechanics during in vivo physiological activity. A great deal of research has gone into determining parameters important to proper long-term joint function. Indicators of potential wear performance in ultra-high molecular weight polyethylene (UHMWPE) total joint replacement components include contact stress and area due to articulations, and tibio-femoral and patello-femoral kinematics. All have been used to compare implant designs and serve as a basis for differentiation of systems.
