A retrospective study was made of 270 patients and 284 knees with acute patellar dislocation treated operatively. The mean follow up time was 4.1 years. Medical history revealed 21.1% of cases with previous dislocations and 15.6% of cases with family occurrence of patellar dislocation. The dislocation resulted from an athletic performance in 41.5% of cases. The sport events most often associated with patellar dislocation were soccer, gymnastics, and ice hockey. All cases were treated with reefing of medial capsule. Release of lateral patellar retinacula was performed in 243 cases. Two cases were treated primarily with the Elmslie-Roux-Trillat procedure. The subjective result of operative treatment was better and the redislocation rate was lower if the injury mechanism was traumatic rather than non-traumatic and if there was no history for family occurrence of patellar dislocation.
对270例患者的284个膝关节急性髌骨脱位手术治疗进行回顾性研究。平均随访时间为4.1年。病史显示,21.1%的病例既往有脱位史,15.6%的病例有家族性髌骨脱位。41.5%的病例脱位是由运动表现引起的。与髌骨脱位最常相关的体育项目是足球、体操和冰球。所有病例均采用内侧关节囊紧缩术治疗。243例进行了外侧髌支持带松解。2例主要采用Elmslie-Roux-Trillat手术治疗。如果损伤机制为创伤性而非非创伤性,且无家族性髌骨脱位病史,则手术治疗的主观效果较好,再脱位率较低。
