title: Long-term results of Alpina Postero-stabilized total knee replacement: 10- to 16-year follow-up.
abstract: One hundred and ninety-four primary knee arthroplasties were done between 1992 and 1998 with Alpina Postero-Stabilized prosthesis. Eighty-eight knees were available for the long-term follow-up at a mean of 12 years. The mean IKS score improved from 103.1 ± 21.9 points preoperatively to 161.5 ± 25.6 at the latest follow-up (P < 0.001). Eighty-four percent of the knees were rated good and excellent. The mean flexion significantly improved from 110° preoperatively to 117.5° at the latest follow-up (P < 0.001). Two knees were revised: 1 due to infection and 1 due to femorotibial malalignment. Eight other knees were revised: 7 for isolated patella addition, 1 for patella replacement. Excluding patella failure, the 12-year Kaplan-Meier survivorship for the entire cohort was 98.8 (95% CI, 97.2-100%). Alpina Postero-Stabilized TKA showed good long-term results.
