We have studied a consecutive series of 72 salvage knee procedures using a Kinematic rotating hinge prosthesis performed in a single arthroplasty unit between 1983 and 1997. Clinical and radiographic assessment of the survivorship of the Kinematic rotating hinge total knee arthroplasty (Howmedica, Rutherford, NJ) were analyzed. Survival analysis revealed a best-case 10-year implant survival of 90%. Concurrently, this group of patients exhibited a significant and sustained improvement in Knee Society Score and pain relief after implantation of a rotating hinge component. There were 10 deaths due to unrelated causes during the study period. This constrained hinged prosthesis remains a viable option in the face of gross deformity, bone loss, and failed multiple previous surgical procedures.
我们研究了1983年至1997年间在单个关节置换单元中使用运动旋转铰链假体进行的连续72例挽救性膝关节手术。对运动旋转铰链全膝关节置换术（Howmedica，新泽西州卢瑟福）的生存率进行了临床和影像学评估。生存分析显示，最佳情况下10年植入物生存率为90%。同时，这组患者在植入旋转铰链组件后，膝关节协会评分和疼痛缓解方面有显著且持续的改善。研究期间有10例因无关原因死亡。面对严重畸形、骨丢失和多次先前手术失败的情况，这种受限铰链假体仍然是一种可行的选择。
