联合手术治疗复发性髌骨脱位

Combined surgical treatment of recurrent patellar dislocation

目的 探讨联合手术治疗复发性髌骨脱位的疗效.方法 回顾性分析采用关节镜探查及治疗、切开松解外侧支持带、紧缩内侧支持带和胫骨结节内移术治疗42例复发性髌骨脱位的临床资料.术后随访,主观评估使用Lysholm和Tegner评分系统,客观评估包括髌骨稳定性检查和影像学检查.结果 42例均获随访,术后Q角均恢复至正常范围,术后体检及影像学复查髌骨均稳定.Lysholm评分术前（48.83±6.07）分,术后（88.09±5.13）分（P＜0.05）;Tegner评分术前（3.80±1.40）分,术后（6.71±1.01）分（P＜0.05）.结论 联合手术治疗复发性髌骨脱位短期疗效满意,远期预后有待观察.

Objective To investigate the effect of combined surgical treatment on recurrent patellar dislocation.Methods A retrospective analysis on the data of 42 cases of recurrent patella dislocation using arthroscopic exploration and treatment,cut the release lateral support belt tightening and shifting technique with medial tibial tuberosity.During postoperative follow-up,subjective evaluation conducted Lysholm and Tegner scoring system,including the patellar stability objective assessment examination and imaging studies.Results Forty-two cases were followed,the postoperative Q angle recovered to normal range in postoperative physical examination and radiologic review,patellar were stable.Lysholm score before surgery was 48.83 ＆#177;6.07,and was（88.09 ＆#177;5.13） min after surgery（P 〈0.05）,Tegner score before surgery was 3.80 ＆#177; 1.40,and was 6.71 ＆#177; 1.01 after surgery（P 〈0.05）.Conclusions The short-term curative efficacy of combined surgical treatment on recurrent patellar dislocation is satisfactory,and the long-term prognosis needs to be farther studied.
