双束重建前交叉韧带及其临床疗效观察

目的 探讨关节镜下胫骨股骨双隧道双束重建前交叉韧带(ACL)的临床疗效.方法 将采用异体腘绳肌腱胫骨股骨双隧道双束重建ACL的患者18例作为实验组,将同期行单束重建的患者28例作为对照组,术后随访时行三维CT、MRI检查,并按照Lysholm、Irrgang评分及IKDC膝关节评分标准进行疗效评价,Lachman试验对重建后膝关节前向稳定性进行评价,轴移试验时重建后膝关节旋转稳定性进行评价.结果 两组共46例患者均获得随访.随访时间6～11个月(平均9个月).随访时两组患者移植物位置及关节功能良好.实验组Lysholm评分(83.6±9.2)分,Irrgang评分(78.8±8.2)分,IKDC评分活动水平正常者15例(83.3%).Lachman试验检查正常者15例,接近正常者3例;轴移试验检查正常者16例,接近正常者2例.对照组Lysholm评分(83.2±8.8)分,Irrgang评分(77.9±8.3)分.IKDC评分活动水平正常者23例(82.14%),Lachman试验检查正常者及接近正常者分别为23例和4例,异常者1例;轴移试验检查正常及接近正常者分别为22例和5例,异常者1例.结论 异体腘绳肌腱胫骨股骨双隧道双束重建ACL可以明显提高重建后膝关节旋转及内翻稳定性,临床疗效预示其前景乐观.

Reconstruction and its clinical observasion of Double-bundle ACL

[Objective] To introduce surgical approach and evaluate therapeutic effect of anterior cruciate ligament(ACL) double-bundle reconstruction with allograft hamstring.[Methods] The experimental group includes 18 cases who accepted double bundle ACL reconstruction with allograft hamstring while the control group includes 28 cases who accepted single-bundle ACL reconstruction with allograft hamstring.The evaluation methods were clinical examination,Lachman test and pivot shift test,radiographic evaluation such a...
