We reviewed 41 knees after arthroscopic lateral release for recurrent dislocation of the patella at a mean follow-up of four years, and graded the results according to the criteria of Crosby and Insall (1976). There were no dislocations after operation in 28 knees (68%); the less satisfactory results were in patients with subluxation of the patella on extension of the knee and those with generalised ligamentous laxity. There were no complications. A characteristic and previously unreported lesion of the patellar surface was seen in eight of the 41 knees. The results of lateral release are better than those reported for other techniques. This treatment, by either open or arthroscopic methods, is recommended.
我们回顾了41例因复发性髌骨脱位接受关节镜下外侧松解术的膝关节，平均随访4年，并根据Crosby和Insall（1976年）的标准对结果进行分级。28例膝关节（68%）术后无脱位；结果不太理想的是膝关节伸直时髌骨半脱位的患者以及有全身性韧带松弛的患者。无并发症发生。在41例膝关节中有8例出现了一种特征性的、以前未报道过的髌骨关节面病变。外侧松解术的结果优于其他技术所报道的结果。推荐采用开放或关节镜方法进行这种治疗。
