Of 700 prosthetic knees inserted during the period from 1969 to 1978, 94 failed; 19 of the failures occurred due to infection. Other obvious mechanisms of failure were wear debris sy novitis, ligament rupture, and patellar dislocation. The majority of prosthetic loosenings occurred on the tibial side. There were five mechanical factors of such loosening: tilt and sink; compression; torsion; toggle; and a combination of these factors. Excluding those who died or were lost to follow-up, the results of revision were 37% good or excellent; 60% fair or poor; and 3% failure. To some extent the results were prosthesis dependent; the semiconstrained prosthesis had a good result in 48%, unlinked hinges a good result in 24%, and a true hinge a good result in 21%. The results in infected cases were poor; of five prosthetic revisions, only one was good. Fusion was found difficult to achieve; of 11 attempts, only six obtained solid fusion. Four amputations were performed, all for infection in hinged knee replacements.
在1969年至1978年期间植入的700个人工膝关节中，有94个出现故障；其中19个故障是由感染引起的。其他明显的故障机制包括磨损碎屑滑膜炎、韧带断裂和髌骨脱位。大多数人工关节松动发生在胫骨侧。这种松动有五个机械因素：倾斜和下沉；压缩；扭转；肘节作用；以及这些因素的组合。排除死亡或失访的患者，翻修结果为37%良好或优秀；60%一般或较差；3%失败。在某种程度上，结果取决于假体；半限制型假体48%效果良好，无连接铰链假体24%效果良好，真正的铰链假体21%效果良好。感染病例的结果较差；在五次假体翻修中，只有一次效果良好。发现融合很难实现；11次尝试中，只有6次获得了牢固的融合。进行了4次截肢手术，均为铰链式膝关节置换感染所致。
