Abstract

Successful reconstruction of the knee involves appropriate patient selection, implant design, implant material and surgical technique. Although the performance and longevity of these arthroplasties continues to improve, their performance is not as long-lasting as we have come to expect from total hip arthroplasty. The work reported in this study depicts the preliminary results of the effect of femoral component varus/valgus position and flexion position using a real-time computerized pressure mapping system (TekScan) for three designs with different geometric congruities
