成人复发性髌骨不稳的综合手术治疗效果分析

摘要

Objective To analyze the clinical effect of medial patellofemoral ligament(MPFL)reconstruction combined with the com-prehensive surgery of anteromedial tibial tubercle transfer and distal shift in the treatment of recurrent patellar instability.Methods The clin-ical data of 60 patients(60 affected knees)with recurrent patellar instability who were admitted to the orthopedics department of Mianyang central hospital in Sichuan Province from April 2012 to September 2016 were retrospectively analyzed.All the patients were examined with knee arthroscopy,lower extremity X-ray,CT and MRI,and they were treated with MPFL reconstruction combined with anteromedial tibial tu -bercle transfer and distal shift comprehensive surgery.All patients were followed up for at least 1 year after operation.The physical indexes, imaging examination indexes and evaluation results of knee function were analyzed before operation and at the last follow -up.Results The follow-up of 60 patients showed that the results of fear test were negative,results of patellar tilt test were symmetrical,and the Q angle re-turned to normal.The activities of flexion and extension were significantly improved,and there was no fractures or dislocation of the patella. Imaging examination showed that the patellofemoral joint was well positioned.At the last follow-up,the patellofemoral congruence angle,de-gree of patellar out-shift and lateral patellar angle of the 60 patients were significantly decreased,and the tibial tuberosity-trochlear groove dis-tance(TT-TG)was also significantly decreased,the differences were significant(P<0.05),and they basically returned to the normal range. At the last follow-up,the Lysholm score and Kujala score were significantly higher than those before operation,the differences were significant (P<0.05).Conclusion The clinical effect of MPFL reconstruction combined with anteromedial tibial tubercle transfer and distal shift com -prehensive surgery is satisfying in the treatment of recurrent patellar instability,which has great significance for relieving symptoms and resto-ring the function of the knee.%目的 分析内侧髌股韧带(MPFL)重建+胫骨结节内移+远端移位的综合手术治疗复发性髌骨不稳的临床效果.方法 回顾性分析2012年4月至2016年9月四川省绵阳市中心医院骨科收治的60例(60膝)复发性髌骨不稳患者的临床资料,均给予膝关节镜、下肢X射线片、CT、MRI检查,实施MPFL重建+胫骨结节内移+远端移位等综合手术治疗,术后至少随访1年,分析术前、术后末次随访物理学指标、影像学检查指标及膝关节功能评价结果.结果 60例患者术后随访显示恐惧试验均为阴性、髌骨倾斜试验对称,Q角恢复正常;屈伸活动、运动能力较术前有明显改善,未发生骨折、髌骨再脱位,影像学显示髌股关节对位良好.与术前相比,60例患者术后末次随访髌股适合角、髌骨外移度、外侧髌骨角显著降低,胫骨结节-股骨滑车间距(TT-TG)显著缩小,差异有统计学意义(P<0.05),且均恢复到正常范围.术后末次随访Lysholm评分、Kujala评分显著高于术前,差异有统计学意义(P<0.05).结论 内侧髌股韧带(MPFL)重建+胫骨结节内移+远端移位治疗复发性髌骨不稳的临床效果满意,对缓解症状和恢复膝关节功能有重要意义.
