髌骨双骨通道治疗髌骨脱位的临床观察

Clinical Observation of Patella Double Bone Channel in the Treatment of Patellar Dislocation

目的观察关节镜下髌骨双骨通道治疗髌骨脱位的临床效果。方法回顾性分析我科自2016年3月至2017年3月收治的髌骨脱位的15例患者资料,均实施了关节镜下外侧支持带松解、内侧髌股韧带重建(髌骨双骨通道)手术,术后进行康复训练。观察患者脱位的复发情况,比较术前及术后膝关节功能评分、髌骨Q角、倾斜角(PTA)及胫骨结节-滑车间距(TT-TG)。结果患者术后Q角、PTA、TT-TG值均较术前有所降低,且术后膝关节的功能评分均较术前提高,P<0.05。结论关节镜下髌骨双骨通道治疗髌骨脱位效果满意,可在临床推广。

Objective To observe the clinical effect of patellar double dislocation under arthroscopy in the treatment of patellar dislocation. Methods The data of 15 patients with patellar dislocation admitted to our department from March 2016 to March 2017 were retrospectively analyzed. All patients underwent arthroscopic lateral retinaculum release and medial patellofemoral ligament reconstruction(patellofemoral double-bone access) and rehabilitation training after operation. The recurrence of dislocation was observed, the knee function score, patellar Q angle, tilt angle(PTA) and tibial tubercle-slip workshop distance(TT-TG) were compared before and after operation. Results The Q-angle, PTA and TT-TG values after operation were lower than those before operation, and the functional score of knee joint after operation was higher than that before operation, P<0.05. Conclusion Arthroscopic treatment of patellar dislocation with patella double bone channel is satisfactory and can be popularized in clinical practice.
