Thirty-five patients with habitual dislocation of the patella in flexion were reviewed; eight were bilaterally affected. Each had undergone quadricepsplasty with an average follow-up of 6 years 9 months. Bands or contractures, most commonly in vastus lateralis, the iliotibial tract and rectus femoris were seen in each. Redislocation was seen in 12 knees. At review, 79% of the knees were normal. Quadriceps lengthening is an essential part of treatment and must be performed proximally. Causes for failure include reformation of contractures and failure to correct the initial abnormality fully.
对35例屈膝位习惯性髌骨脱位患者进行了回顾性研究；其中8例为双侧受累。每位患者均接受了股四头肌成形术，平均随访时间为6年9个月。每位患者均可见束带或挛缩，最常见于股外侧肌、髂胫束和股直肌。12个膝关节出现了再脱位。复查时，79%的膝关节恢复正常。股四头肌延长术是治疗的重要组成部分，必须在近端进行。治疗失败的原因包括挛缩复发和未能完全纠正初始异常。
