摘要
目的：探讨大收肌肌腱转位重建内侧髌股韧带（MPFL）治疗青少年髌股关节不稳的临床效果。方法18例（21膝）青少年髌股关节不稳（包括习惯性髌骨脱位和复发性髌骨脱位）患者，在关节镜辅助下行外侧支持带松解，保留股骨大收肌止点的大收肌肌腱转位重建MPFL。随访12～30个月，记录并发症，比较术前、术后髌股外侧角、Lysholm膝关节功能综合评分。结果18例术后均无切口感染，无再脱位，髌骨稳定性良好，无骨骺损伤，膝关节屈伸功能良好。髌骨恐惧试验均阴性。术后外侧髌股角、Lysholm膝关节功能综合评分均较术前有明显改善[（10.3±4.1）°比（-3.8±4.9）°、（92.7±3.6）分比（61.5±2.4）分]，差异有统计学意义（P＜0.01）。结论保留股骨大收肌止点的大收肌肌腱转位重建MPFL可显著恢复髌股关节稳定性，是临床治疗青少年髌股关节不稳的有效方法之一。
Objective To investigate the clinical effect of adductor magnus tendon transposition with arthroscopic in reconstruction medial patellofemoral ligament （MPFL） for the treatment of patellofemoral joint instability of adolescents. Methods Eighteen juvenile patients （21 knees） with patellofemoral joint instability （including chronic patellar dislocation and recurrent patellar dislocation） were treated with adductor magnus tendon transposition for MPFL reconstruction, combined with lateral patellofemoral ligament release. They were followed up for 12- 30 months. The complications, patellofemoral angles and Lysholm scores before and after operation were recorded and compared. Results There was no complications such as wound infection, redislocation, patellofemoral joint instability and epiphyses injured. All patients got excellent knee flexion and extension function. Patella fear tests were all negative. The patellofemoral angles and Lysholm scores after operation were improved significantly than those before operation：（10.3 ± 4.1）° vs. （-3.8 ± 4.9）°, （92.7 ± 3.6） scores vs. （61.5 ±2.4） scores, P〈0.01. Conclusions Adductor magnus tendon transposition with arthroscopic in reconstruction MPFL can significantly improve the stability of patellofemoral joints. This is one of the effective methods for the treatment of patellofemoral joint instability of adolescents.
