Fifty-two patients (sixty knees) who had a diagnosis of either patellar subluxation or dislocation had an operation consisting of a lateral release and proximal realignment of the patella. The duration of follow-up ranged from two to nine years. At the latest follow-up, forty-two (80.8 per cent) of the patients had a good or an excellent clinical result; only one patient had redislocation of the patella. The results were not affected by the grade of chondromalacia that was present at the time of operation; however, the differences in the results as correlated with the age and sex of the patient were statistically significant, the older patients having poorer results and the male patients, better results. Roentgenographic analysis of the postoperative position of the patella, as seen on the view described by Merchant et al., revealed that centralizing the patella in the intercondylar sulcus yielded the most favorable results.
52例诊断为髌骨半脱位或脱位的患者（60个膝关节）接受了包括外侧松解和髌骨近端重新排列的手术。随访时间为2至9年。在最近一次随访时，42例（80.8%）患者获得了良好或优秀的临床结果；只有1例患者髌骨再次脱位。结果不受手术时存在的软骨软化分级的影响；然而，结果与患者年龄和性别的差异具有统计学意义，年龄较大的患者结果较差，男性患者结果较好。根据Merchant等人描述的视图对术后髌骨位置进行的X线分析显示，将髌骨置于髁间沟中央可产生最有利的结果。
