title: [Patellofemoral replacement for severe patellofemoral osteoarthritis: a 2-10 years follow-up study].
abstract: OBJECTIVE
  To evaluate the therapeutic effects of patellofemoral replacement for severe patellofemoral osteoarthritis.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Patellofemoral replacement is effective in treating severe patellofemoral osteoarthritis in appropriate cases.
