目的探讨改良股四头肌成形术治疗创伤性膝关节僵硬治疗效果。方法在1996年1月至2003年8月间应用改良股四头肌成形术治疗22例创伤性膝关节伸直位强直病人。结果术前平均伸屈膝关节0°～49°,术后平均随访16个月,平均伸屈膝关节可达0°～110°,未见继发血肿感染,髌前皮肤坏死及伸膝无力等并发症。结论改良股四头肌成形术治疗创伤性膝关节僵硬手术安全,疗效好,术后并发症少。

Objective To investigate the theraputic effects of a modified quadriceps-patellae tenoplasty for the treatment of extension ankylosis of the knee joint. Methods 22 patients with extension ankylosis of the knee joint were treated by modified quadriceps-patellae tenoplasty from Jun 1996 to August 2003. Results Before the operation, average flexion function of knee was 49°.All cases were followed up for an average of 16 months. The postoperative average flexion function of knee joint were increased to 110°. The function of knee joint were recovered without haematoma, necrosis of skin and delayed extension of knee joint.
