A modified Thompson quadricepsplasty for the stiff knee

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 degrees (75 to 150), The final mean gain in movement was 67.6 degrees (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.
