In 200 low friction knee arthroplasties with a minimum follow-up of 2 years the primary goal of relief from pain was accomplished in most patients. However, the evaluation of the result of a knee arthroplasty is difficult. Many of the patients who rated good or better had, to some extent, patellofemoral complaints. Cold flow deformation and prosthetic loosening is a definite concern about the tibial component. A longer follow-up study is needed to better evaluate the significance of the one to 2 mm radiolucent line at the bone cement interface of the tibial component. Collateral and cruciate ligament deterioration with time is also of concern and warrants careful follow-up. Although most patients patients in this series were greatly relieved of pain, even better results might have been obtained if the arthroplasty included the patellofemoral joint and a more substantial tibial component with better fixation. By our rating criteria, rheumatoid patients, in general, were benefited the most. Patients, surgeons and engineers realize that the natural human knee joint is a remarkable product of adaptive evolution, and that it may be imitated with increasing success though it can never be duplicated.
在200例低摩擦膝关节置换术中，至少随访2年，大多数患者实现了缓解疼痛的主要目标。然而，评估膝关节置换术的结果很困难。许多评价为良好或更好的患者在一定程度上存在髌股关节问题。冷流变形和假体松动是胫骨部件的一个明确问题。需要进行更长时间的随访研究，以更好地评估胫骨部件骨水泥界面处1至2毫米透亮线的意义。随着时间的推移，侧副韧带和交叉韧带的退化也令人担忧，需要仔细随访。虽然该系列中的大多数患者疼痛得到了极大缓解，但如果关节置换术包括髌股关节和具有更好固定的更坚固的胫骨部件，可能会获得更好的结果。根据我们的评级标准，一般来说，类风湿患者受益最大。患者、外科医生和工程师都认识到，天然的人体膝关节是适应性进化的杰出产物，虽然永远无法复制，但可以越来越成功地进行模仿。
