摘　　要：目的：探讨改良髌骨双骨道及界面螺钉固定游离半腱肌腱解剖重建内侧髌股韧带治疗创伤性髌骨脱位的疗效。方法：2010年1月至2012年10月对30例创伤性髌骨脱位患者关节镜辅助下行内侧髌股韧带（MPFL）双束解剖重建,移植半腱肌腱,髌骨固定方式采用改良双骨道及界面螺钉挤压固定。结果：所有患者随访时间6~18个月,平均12个月。30例手术后均无再脱位,髌骨运动轨迹正常,关节活动无受限,恐惧试验阴性,未发生髌骨骨折,髌骨外移率、髌股适合角及外侧髌股角较术前改善（P〈0.05）。结论：采用改良髌骨双骨道及界面螺钉固定技术解剖重建内侧髌股韧带,手术方式简单、损伤小、腱骨结合处固定良好、髌骨稳定性好、并发症少。Objective To study the effect of modified patellar double bone tunnel and interface-screw fixation of free semitendinosus tendon on the outcome of anatomy reconstruction of medial patellofemoral ligament. Methods From January 2010 to October 2012,30 patients with traumatic patellar dislocation underwent medial patellofemoral ligament（MPFL） reconstruction with modified patellar double bone tunnel and interface-screw fixation of free semitendinosus tendon. Results All patients were followed up for an average of 12 months（6 to 18 months）. There was no patellar redislocation after surgery,the patellar trajectory and range of motion from dorsiflexion 0° to flexion 120° were normal. As compared with before surgery,the result of fear test,patellofemoral congruence angle,and lateral patellofemoral angle improved significantly（P 〈0.05）. Conclusion Modified patella double bone tunnel and interference screw fixation techniques for reconstruction of MPFL caused by traumatic patellar dislocation has advantages of simple operation procedure,less tissue damage,well patellar stability,and fewer complications.
