Anterior cruciate ligament (ACL) injury is one of the most common ligament injuries of the knee joint, especially in athletes. ACL reconstruction has been widely performed for many years. There have been many innovations of surgical instruments and improvements in surgical techniques, such as the single-incision endoscopic transtibial approach. Recently, many surgeons have focused on anatomic double-bundle ACL reconstruction. Anatomical graft position is one of the most important issues in ACL reconstruction, and it does not matter whether single- or double-bundle ACL reconstruction is performed. As clinicians we recommend anatomical ACL reconstruction for both athletes and non-athletes as a way of reducing the risk of knee osteoarthritis for ACL injured patients.
