目的 探讨应用自体腘绳肌肌腱加腓骨长肌腱前束与应用LARS人工韧带重建断裂后交叉韧带 (PCL) 术后患膝功能与力学稳定性恢复的疗效对比.方法 43例后交叉韧带断裂患者, 根据术中采用移植物的不同分成两组:LARS人工韧带组 (22例) 和自体腘绳肌肌腱加腓骨长肌腱组 (21例) .术后随访时间至少2年, 评价指标采用膝关节Lysholm评分、IKDC评分及Tegner评分评定患膝功能, 后抽屉试验评定力学稳定性.结果 术后43例随访完整, 术后两组膝关节稳定性及功能指标的结果均较术前显著提升, 差异均有统计学意义 (P <0.05);同时, 对于所有各项术后评分, 两组之间的差异无统计学意义 (P> 0.05) .结论 应用自体腘绳肌肌腱加腓骨长肌腱前束与应用LARS人工韧带重建断裂后交叉韧带均可取得满意的临床疗效, 两者疗效类似.%Objective To investigate the effect of the use of autologous hamstring tendon plus peroneal longus tendon and the application of LARS artificial ligament reconstruction of posterior cruciate ligament (PCL) knee function and recovery of mechanical stability. Methods Forty-three patients with posterior cruciate ligament rupture were divided into two groups according to the type of graft used during the operation : the LARS artificial ligament group (22 cases) and the autologous hamstring tendon plus peroneal longus tendon group (21 cases). The postoperative follow-up time was at least two years. The knee joint function was evaluated using the knee joint Lysholm score, IKDC score, and Tegner score. The post-drawer test evaluated mechanical stability. Results After 43 cases were followed up completely, the knee joint stability and function indexes of the two groups were significantly improved compared with preoperative ones. The differences were statistically significant (P < 0.05).At the same time, for all postoperative scores, two There was no significant difference between groups (P> 0.05).Conclusion The application of autologous hamstring tendons plus peroneal longus tendon anterior bundle and LARS artificial ligament reconstruction posterior cruciate ligament can achieve satisfactory clinical curative effect.
