Abstract
Anterior cruciate ligament (ACL) injury is a common knee sports injury, with proximal ACL tears accounting for most cases. Arthroscopic ACL preservation has shown great potential in repairing ACL anatomic and biological function, with less tissue damage and slightly higher failure rates. Although many techniques for repairing the ACL have been developed, there are still many problems with the existing technology, such as the cumbersome operation of the traditional hook and needle breakage of the Scorpion suture passer (Arthrex). Herein, to further improve operational convenience and reliability, we developed a continuous bundle suture technique for primary repair of proximal ACL tears with suture anchor fixation. This technique aims to achieve continuous suturing with no additional auxiliary suture for guiding suturing by using a passer as a pusher in the suture hook to push out the suture loaded in the tip of the hook after the hook passes through the ligament. This technique takes advantage of the economics of the suture hook and the convenience of the Scorpion suture passer, allowing for flexible application of the suture hook to conveniently achieve anteromedial and posterolateral bundle repair for patients with proximal ACL tears.
