The ACL is a complex structure, and its replacement involves precise surgical technique, which relates directly to its function in constraining anterior tibial translation. Many techniques have been developed for reconstruction of the ACL. Here we have described our method of choice for arthroscopically assisted graft placement, which uses the middle-third patellar tendon autograft placed using a press-fit fixation technique. This technique was developed to avoid drawbacks encountered with fixation using an interference screw. Biomechanical testing has shown this technique to be similar in pull-out strength to fixation obtained with an interference screw, but without the associated technical difficulties. One other benefit of this technique, which is not readily apparent, and not one that we, as surgeons, would ever hope to take advantage of, is that should a revision ACL reconstruction be necessary in the future, there is no interference screw in the femur to remove.
前交叉韧带是一个复杂的结构，其重建需要精确的手术技术，这直接关系到它在限制胫骨前移方面的功能。已经开发出许多用于前交叉韧带重建的技术。在此我们描述了我们选择的关节镜辅助移植物置入方法，该方法使用中三分之一髌腱自体移植物，并采用压配固定技术。开发该技术是为了避免使用干涉螺钉固定时遇到的缺点。生物力学测试表明，该技术的拔出强度与使用干涉螺钉固定相似，但没有相关的技术难题。该技术的另一个好处并不明显，而且作为外科医生我们也不希望利用这一点，即如果将来需要进行前交叉韧带翻修重建，股骨中没有干涉螺钉需要取出。
