Experiments were carried out to determine the optimum conformity between the femoral and tibial condyles in condylar replacement knee prostheses. Wear tests and observations from removed prostheses indicated that both high and low conformity produced characteristic abrasion and fatigue. Partly conforming condyles provided stability under load-bearing but allowed laxity to occur. Fixation to resist the various forces on the tibial components was enhanced by a short central intramedullary peg. Partial conformity is proposed as the optimum configuration between femoral and tibial components.
开展了实验以确定髁置换膝关节假体中股骨髁与胫骨髁之间的最佳贴合度。磨损测试以及对取出假体的观察表明，高贴合度和低贴合度都会产生典型的磨损和疲劳。部分贴合的髁在承重时提供稳定性，但会出现松弛。通过短的中央髓内钉增强了对胫骨部件上各种力的抵抗固定。建议部分贴合作为股骨和胫骨部件之间的最佳构型。
