关节镜下经胫骨前外侧骨道重建后交叉韧带的临床研究

Clinical Study for Arthroscopic Reconstruction of Posterior Cruciate Ligament through Anterolateral Tibial Tunnel

目的:评价关节镜下经胫骨前外侧骨道重建后交叉韧带的临床疗效。方法:收集2012年1月至2015年12月在本科确诊为后交叉韧带断裂并在关节镜下经胫骨前外侧骨道行后交叉韧带重建的患者共30例;年龄21~45岁(平均29岁),男24例、女6例;合并半月板损伤10例,后外侧复合体损伤4例。通过关节镜探查并将取下的自体半腱及股薄肌腱用于重建后交叉韧带,采用韧带标准评价表(IKDC)和Lysholm膝关节功能评分表评估患膝功能。结果:所有随访患者术后无感染发生,术后屈膝活动度为全部超过120°.患肢功能均恢复良好,优良率达100%.结论:关节镜下经胫骨前外侧骨道重建后交叉韧带,能满意地恢复膝关节功能,可作为后交叉韧带重建的选择方法之一。

Objective：To evaluate the clinical effect of arthroscopic reconstruction of PCL through anterolateral tibial tunnel.Methods：From 2012 to 2015,30 patients with PCL injury were treated with arthroscopic reconstruction of PCL through anterolateral tibial tunnel.There were 24 males and 6 females,aged from 21 to 45 years old（average 29 years old）.Among them,10 patients accompanied with meniscus injury,4 patients accompanied with posterolateral complex injury.The autologous hamstring tendon was used to reconstruct the posterior cruciate ligament arthroscopically,and the IKDC and Lysholm knee score scale were used for functional evaluation.Results：No infection occurred after operation,and the knee flexion was over 120 degrees postoperatively.The limb function recovery was satisfied,and the excellent and good rate was 100%.Conclusion：Arthroscopic reconstruction of PCL through anterolateral tibial tunnel can satisfactorily restore the function of the knee joint,and it is one of the options for posterior cruciate ligament reconstruction.
