Objective To analyze the feasibility and clinical effect of gracilis muscle in the reconstruction of medial collateral ligament. Methods Sixty-eight patients with rupture of the medial collateral ligament treated in our hospital from February 2012 to June 2015 were selected, which were divided into the observation group and the con-trol group according to the different treatment plans, with 34 patients in each group. The control group was treated with routine ligament repair, while the observation group was treated with medial collateral ligament reconstruction. The complication rate, clinical efficacy, Lysholm score, and instability score of the two groups were observed and com-pared. Results Before surgery, the Lysholm knee score and the Lysholm knee score of instability were basically con-sistent in the two groups, with no statistically significant difference [(51.2±8.3) vs (52.1±8.6), (8.1±2.4) vs (8.2±2.5), P>0.05]. After surgery, the Lysholm knee score and the Lysholm knee score of instability were increased to varying degrees in the two groups, showing statistically significant differences with those before surgery [(87.6 ± 11.2) vs (73.2 ± 10.4), (19.6±2.7) vs (12.6±2.5), P<0.05], and the increase in the observation group were more significant (P<0.05). The complica-tion rate of the observation group was significantly lower than that in the control group (2.9%vs 17.6%, P<0.05), and the ex-cellent and good rate of the observation group was significantly higher (94.1%vs 67.6%, P<0.05). Conclusion Gracilis muscle can be a recommended choice for reconstruction of medial collateral ligament, with good recovery after recon-struction, which is suitable for long-term clinical application.%目的 分析股簿肌重建内侧副韧带的可行性与其临床疗效.方法 选择2012年2月至2015年6月于我院接受治疗的68例内侧副韧带断裂患者作为研究对象,根据治疗方案不同,分为观察组和对照组,每组34例.对照组患者给予常规韧带修复术治疗,观察组患者给予内侧副韧带重建术治疗.观察并比较两组患者治疗前后的膝关节Lysholm评分、不稳评分等一般情况,两组患者的并发症发生率及临床疗效.结果 术前两组患者的膝关节Lysholm评分及[(51.2±8.3)分vs (52.1±8.6)分]膝关节Lysholm不稳评分[(8.1±2.4)分vs (8.2±2.5)分]均基本相符,差异均无统计学意义(P>0.05);术后两组患者的膝关节Lysholm评分[(87.6±11.2)分vs (73.2±10.4)分]及膝关节Lysholm不稳评分[(19.6±2.7)分vs (12.6±2.5)分]均有不同程度升高,差异均具有统计学意义(P<0.05),但观察组患者的膝关节Lysholm评分及膝关节Lysholm不稳评分的上升幅度更为显著,差异均具有统计学意义(P<0.05);观察组患者的并发症发生率明显低于对照组(2.9%vs 17.6%),临床疗效的优良率明显高于对照组(94.1%vs 67.6%),差异均具有统计学意义(P<0.05).结论 股簿肌肌腱可以很好地重建内侧副韧带,且重建术后患者的功能恢复效果良好,适合临床推广应用.
