Résumé
PURPOSE: In this study, the effect arthroscopic adhesiolysis and the need for additional quadricepsplasty were evaluated by reviewing the patients 'data. MATERIALS AND METHODS: From July 1996 to January 2002, 18 patients received operation for the stiff knee. The patients were classified into 2 groups according to treatment method - Group 1: arthroscopic adhesiolysis and Group 2: arthroscopic adhesiolysis plus Judet quadricepsplasty. The Judet quadricepsplasty was performed when maximal knee flexion was not achieved over 90 degree even after arthroscopic adhesiolysis. We reviewed primary causes and the duration of contracture of stiff knee. Preoperative, postoperative, and final range of motion was evaluated. RESULTS: Preoperative, postoperative, and final range of motion was evaluated. In group 1, the average range of motion was 34 degree preoperatively, 107 degree intraoperatively, and 103 degree at the last follow-up. In group 2, the average range of motion, 26 degree preoperatively, 67 degree (after arthroscopic adhesiolysis)-115 degree(after quadricepsplasty) intraoperatively, and 112 degree at the last follow-up. CONCLUSION: Arthroscopic adhesiolysis has an effect in releasing intrarticular adhesion. Additional quadricepsplasty should be considered when the duration of contracture is over 12 months and primary causes of stiff knee is distal femur fracture which causes damages in the quadriceps muscle.
