title: Patellofemoral arthroplasty: 7-year mean follow-up.
abstract: Patellofemoral arthroplasty has had renewed interest with the purpose of this study to evaluate its outcomes. Between 2001 and 2006, 43 were performed in 37 patients who had a mean follow-up of 7 years (range, 4-8 years). Patient outcomes were determined using Knee Society objective and function scores, revision rates, and complication rates. The 5-year Kaplan-Meier survivorship was 95%. Knee Society objective scores improved from a mean of 64 points (range, 57-68 points) to 87 points (range, 50-100 points), and functional scores improved from a mean of 48 points (range, 45-50 points) to 82 points (range, 20-100 points). This study shows maintained successful clinical and radiographic results at mean 7-year follow-up for patellofemoral arthroplasty.
