Mid-term results of an AGC total knee arthroplasty system survival and function analysis: 2- to 8-year follow-up results.

Between 1993 and 1999, 148 total knee arthroplasties were performed in Dipreca Hospital; 94 were anatomically graduated components (AGC) cam-and-groove posterior-stabilized total knee arthroplasties. All patients underwent implantation with a cemented posterior cruciate-substituting design, with resurfacing of 3 components. Mean age at surgery was 69 years, and patients were followed up for a minimum of 2 years (range, 2-8). The survival analysis at 8 years was 96.6%. Revision for any reason was considered to be the endpoint. Of patients, 3.2% were lost to follow-up. The mean knee pain and function scores were 89 and 64 of 100, respectively. The scores were also analyzed by categories. This knee arthroplasty follow-up analysis shows excellent midterm results.
