复发性髌骨脱位的治疗进展

复发性髌骨脱位主要表现为髌骨反复性脱位、"打软腿"等,大多有外伤史或膝关节发育不良的基础。传统治疗方法包括内侧支持带紧缩、外侧支持带松解、胫骨结节移位、股骨滑车成型术等。近年来随着对内侧髌股韧带(MPFL)解剖结构及生物力学的研究逐渐深入,MPFL防止髌骨脱位的作用越来越被重视,通过重建MPFL来恢复髌骨正常轨迹日益增多。目前尚无一种术式能够完全治疗复发性髌骨脱位,具体治疗根据患者的解剖及生物力学情况,选择合适的术式联合治疗,恢复患者的髌骨稳定性、下肢力线及尽可能恢复膝关节功能。

Current therapy progress on the recurrent patellar dislocation

Patients who suffer from the recurrent patellar dislocation mainly show the recurrent dislocation of patellar,giving way,most patients have the history of trauma or dysplasia of keen joint. Traditional therapies of recurrent patellar dislocation include medical retinaculum placation,lateral retinaculum release,tibial tubercle osteotomy,femoral trochleoplasty etc. In recent years,with the development of anatomical and biomechanical researches on medial patellofemoral ligament(MPFL),more and more experts focus on the role of MPFL played in preventing the patellar dislocation. The treatment of recovering and correcting patellar tracking through MPFL reconstruction has been increasing gradually. However,till now,there was no therapy which could heal the recurrent patellar dislocation completely. The specific therapies of recurrent patellar dislocation are combination therapies,decided according to the anatomical and biomechanical conditions of patients,for recovering the stability of patients'' patellar,the lower limb alignment and the function of keen-joint.
