In our original report, 97 patients (114 knees) underwent revision total knee arthroplasty with use of a Legacy Constrained Condylar Knee prosthesis (LCCK; Zimmer), with a mean follow-up of 7.2 years (range, 5 to 10 years). The purpose of the present study was to determine the long-term clinical and radiographic results, with a focus on component fixation and the prevalence of osteolysis. At a mean follow-up of 19.2 years (range, 16 to 21 years), re-revision of the LCCK prosthesis had been performed in 10 knees (9%). The rate of survival at 19.2 years was 96% (95% confidence interval [CI], 94% to 100%) with reoperation for mechanical failure as the end point, and 91% (95% CI, 87% to 98%) with reoperation for any reason as the end point. One knee had circumferential osteolysis around the components. LEVEL OF EVIDENCE:: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
在我们最初的报告中，97 例患者（114 膝）接受了 Legacy Constrained Condylar Knee 假体（LCCK；Zimmer）的翻修全膝关节置换术，平均随访 7.2 年（5-10 年）。本研究的目的是确定长期临床和影像学结果，重点关注组件固定和溶骨的发生率。在平均 19.2 年的随访（范围 16-21 年）中，10 例（9%）膝关节再次进行了 LCCK 假体翻修。以机械故障为终点的 19.2 年生存率为 96%（95%可信区间 [CI]，94%至 100%），以任何原因再次手术为终点的生存率为 91%（95% CI，87%至 98%）。1 例膝关节周围出现环形骨溶解。证据水平：治疗水平 IV。有关证据水平的完整描述，请参见作者说明。
