Of 27 patients sustaining primary patellar dislocations, 20 were treated with immobilization and subsequent physiotherapy (including nine patients who underwent arthroscopy) and seven with immediate surgical stabilization and lateral release. The patients with predisposing factors such as patellofemoral malalignment, abnormal patellar configuration, and a history of prior symptoms of instability were more prone to recurrent dislocation and may benefit from operative intervention. Although the incidence of recurrence among those individuals can be decreased, at least 30% to 50% of all patients having sustained a primary patellar dislocation will continue to have symptoms of instability and/or anterior knee pain.
在27例初次髌骨脱位患者中，20例采用固定及后续物理治疗（包括9例行关节镜检查的患者），7例采用立即手术稳定及外侧松解。存在髌股关节对线不良、髌骨形态异常及既往不稳定症状史等易感因素的患者更容易复发脱位，可能从手术干预中获益。尽管这些患者的复发率可以降低，但所有初次髌骨脱位患者中至少30%至50%仍会持续出现不稳定症状和/或前膝疼痛。
