To evaluate the therapeutic effects of patellofemoral replacement for severe patellofemoral osteoarthritis.
Patellofemoral replacement was performed in 30 patients (36 knee joints) with severe patellofemoral osteoarthritis, among whom were 5 males and 25 females. The patients ranged in age from 36 to 74 years old (mean +/- s, 55.8 +/- 8.5) and were followed up for 2-10 years.
Significant improvement was made in both the knee score and functional score after the patellofemoral replacement. The effective rate was 88.9% and 91.7% evaluated with knee score and functional score respectively.
Patellofemoral replacement is effective in treating severe patellofemoral osteoarthritis in appropriate cases.
