Abstract: Anterior cruciate ligament (ACL) reconstruction is a standard treatment for ACL injuries, but it has drawbacks of a low rate of return to sports and a high incidence of osteoarthritis. In recent years, research has found that the proximal ACL tissue has a healing potential after injury. For patients who meet the indications for surgical repair, primary repair of ACL can achieve therapeutic effects comparable to ACL reconstruction, showing advantages of smaller trauma and preservation of the original ligament. Therefore, this surgical approach has received renewed attention and adoption, becoming an important supplement to ACL reconstruction. This article reviews the factors leading to the failure of previous open primary repair, and analyzes the current popularity of arthroscopic ACL primary repair. Moreover, it summarizes the surgical indications, repair procedures, rehabilitation, and return to sports of ACL primary repair, hoping to promote the clinical application of this surgical approach.
