A modified Thompson quadricepsplasty for the stiff knee

Abstract

Between March 1987 and March 1997, we performed a modified Thompson quadricepsplasty on 20 stiff knees and followed the patients for a mean of 35 months (24 to 52). After the operation, the knee was immobilised in flexion and periodically extended. At the final follow-up, the mean active flexion was 113.5° (75 to 150). The final mean gain in movement was 67.6° (5 to 105). One patient had a deep infection which resolved after wound care and intravenous antibiotics. The modified Thompson quadricepsplasty with appropriate postoperative care can give good results.
