anatomical individualized acl reconstruction

The anterior cruciate ligament (acl) is composed of two bundles, which work together to provide both anteroposterior and rotatory stability of the knee. understanding the anatomy and function of the acl plays a key role in management of patients with acl injury. anatomic acl reconstruction aims to restore the function of the native acl. femoral and tibial tunnels should be placed in their anatomical location accounting for both the native acl insertion site and bony landmarks. one main component of anatomical individualized acl reconstruction is customizing the treatment according to each patient’s individual characteristics, considering preoperative and intraoperative evaluation of the native acl and knee bony anatomy. anatomical individualized reconstruction surgery should also aim to restore the size of the native acl insertion as well. using this concept, while single bundle acl reconstruction can restore the function of the acl in some patients, double bundle reconstruction is indicated in others to achieve optimal outcome.
