[Patelloplasty for extensive lesions of the patellar cartilage]

We have been able to review 100 cases of patelloplasty for extensive lesion of the patellar cartilage with an average follow up of 5 years. The technic for the procedure is described. The study of the results (64% of good and very good results) allow us the emphasize the criteria for best indications and technic. We prefer this technic to patellectomy or femoro-patellar prothesis in the cases of symptomatic degenerative arthrites with patellar excentration with special mention on the fact that it does not cut bridge to further procedure on the knee.
