Anterior Cruciate Ligament (ACL) Tears
The anterior cruciate ligament, or ACL, is a strong ligament within the knee joint. It stabilizes the knee and is important for staying active in sports and walking. ACL tears often occur from falls or with quick, twisting or pivoting motions when the foot is planted.

ACL surgery is performed using knee arthroscopy, a minimally invasive technique that uses small incisions, a camera, and small instruments to repair or reconstruct the ACL. Newer techniques and innovative implants continue to help patients get back to activity quickly and safely. If reconstruction is necessary, a tendon graft may need to be harvested and prepared.
