[Arthroscopic treatment of chondropathia patellae with lateral release and motor driven instruments]

The treatment of chondromalacia of the patella is a medical problem. There are no sure concepts of therapy. We have analysed the value of the only lateral release or shaving by motorizised instruments or the combination of both methods. After lateral release have many patients no pain but the other methods also helped many patients. The comparison of these groups is impossible because of the different structure. A prospective randomised study has to bring the answer to this question.
