A retrospective analysis was conducted on 539 hips undergoing revision total hip arthroplasty done for instability to report the cumulative risk and factors associated with re-dislocation and re-revision. The cumulative risk of re-dislocation and re-revision for all cause was 34.5% and 45.9% at 15 years, respectively. Multiple variable analyses revealed history of 2 or more previous surgeries, use of head size less than 36 mm, and cup retention to be risk factors for re-dislocation and re-revision. The use of a constrained liner was protective against re-dislocation but was not associated with a lower re-revision rate. Understanding the risk factors associated with re-dislocation or re-revision may help with perioperative decision making in order to decrease the high failure rate seen in this study.
对539例因不稳定而行翻修全髋关节置换术的髋关节进行回顾性分析，以报告再脱位和再次翻修的累积风险及相关因素。15年时，所有原因导致的再脱位和再次翻修的累积风险分别为34.5%和45.9%。多变量分析显示，既往有2次或更多手术史、使用小于36 mm的股骨头尺寸以及髋臼假体固定是再脱位和再次翻修的危险因素。使用限制性衬垫可预防再脱位，但与较低的再次翻修率无关。了解与再脱位或再次翻修相关的危险因素可能有助于围手术期决策，以降低本研究中观察到的高失败率。
