- 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.
