自体腘绳肌腱重建前交叉韧带固定方法研究现状与进展

Anterior cruciate ligament reconstruction with harmstring tendon transplantation

前交叉韧带损伤常用治疗方法为自体腘绳肌腱移植重建术。移植物的固定对于重建早期的稳定性及腱-骨愈合具有重要作用。目前移植物的固定方法多种多样。通常可分为直接固定和间接固定或可分为骨道内固定与非骨道内固定。不同固定方法有不同的固定力学特点,其腱-骨愈合亦不同。目前在临床常用的有界面螺钉、内置纽扣、横穿钉及肌腱结固定等。各种固定方法的临床应用结果均各有优缺点,并不能认为何种固定效果最佳。

The reconstruction with harmstring tendons is the commonly therapic method for the anterior cruciate ligament （ACL） injury. The graft-implant fixation is important for the initial biomechanics stability and the graft-tunnel healing. The methods of fixation are variable, which can be classified by direct fixation and indirect fixation or by in-tunnel fixation and non-in-tunnel fixation. The interface screw, endobutton, cross pin and tendon knot are most commonly used in clinic. No fixation method is superior to all others, for every method has advantages and disadvantages respectively.
