Recurrent dislocation of the patella is a disorder with a complex aetiology. Several surgical procedures have been recommended for its correction, but there are few clinical or radiological guidelines to facilitate the selection of a particular procedure. The results of treating a series of 29 knees are presented with a follow-up of at least 2 years. A significant correlation has been found between the horizontal movement of the centre of the patella on quadriceps contraction (quadriceps pull test) and surgical outcome when lateral release alone is selected for the correction of recurrent patellar dislocation.
复发性髌骨脱位是一种病因复杂的病症。针对其矫正已推荐了多种外科手术方法，但几乎没有临床或放射学指南来辅助选择特定的手术。本文呈现了对29例膝关节进行治疗并至少随访2年的结果。当单独选择外侧松解术来矫正复发性髌骨脱位时，已发现髌骨中心在股四头肌收缩时的水平移动（股四头肌牵拉试验）与手术结果之间存在显著相关性。
