目的比较双束重建与单束重建膝前交叉韧带(ACL)的临床效果。方法分别对31例和30例膝前交叉韧带损伤患者行双束重建与单束重建手术,通过关节稳定性试验、Tegner体育量表评分和术后满意度来评价疗效。结果双束组和单束组Lachman试验阳性分别为1例和7例(P<0.05);边对边差异<3 mm分别为27例和19例(P<0.05);Tegner体育量表评分双束组优于单束组。结论双束重建符合正常膝ACL的空间结构,更能满足膝关节伸直位和扭转位时的生物力学要求。

Objective To compare the clinical effects of arthroscopic single-bundle and double-bundle reconstruction in the repair of anterior cruciate ligament(ACL).Methods Thirty-one patients with ACL rupture were operated by double-bundle reconstruction while thirty patients with ACL rupture were operated by single-bundle reconstruction under arthroscope.Joint stability test,Tegner score and postoperative satisfaction were evaluated.Results Lachman test were positive in 1 case of double-bundle group and 7 cases of single-bundle group(P<0.05);Edge to edge differences were less than 3 mm in 27 cases of double-bundle group and 19 cases of single-bundle group(P<0.05);Tegner score of double-bundle group was better than single-bundle group.Conclusion Double-bundle reconstruction could fit the space structure of normal knee ACL and could better satisfy the biomechanical require of knee joint at unbend and reverse position.
