Objective To investigate the clinical effect of arthroscopy medial patela ligament strengthening and plaster immobilization in treating acute patelar luxation.Methods82 cases with acute patelar luxation in our hospital from August 2013 to August 2014 were selected as study objects.They were divided into two groups,41 cases in each group. Control group was given plaster immobilization treatment and observation group was given arthroscopy medial patela ligament strengthening. Compared the clinical effect of the two groups.Results Patela slant angle of observation group was obviously better than control group after 1 year treatment,the difference was statisticaly significant(P<0.05). Lysholm score of observation group was obviously higher than control group, the difference was statisticaly significant(P<0.05).Conclusion Compared with plaster immobilization, arthroscopy medial patela ligament strengthening in treating acute patelar luxation has better significant effect.%目的：研究分析关节镜内侧髌骨支持带缝合和石膏固定治疗急性髌骨脱位的临床效果。方法选取2013年8月～2014年8月我院收治的急性髌骨脱位患者82例，随机分为两组，各41例。对照组采用石膏外固定治疗，观察组采用关节镜内侧髌骨支持带缝合术治疗，对比两组临床治疗效果。结果观察组在治疗后1年髌骨倾斜角优于对照组，差异有统计学意义（P＜0.05）；观察组各项Lysholm评分均高于对照组，差异有统计学意义（P＜0.05）。结论相比于石膏外固定治疗，关节镜内侧髌骨支持带缝合术治疗急性髌骨脱位效果良好，可提高治疗效果。
