Mont, Michael A. et al.

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.
