The ACL is one of the four major ligaments of the knee that connect the thigh bone (femur) to the lower leg bone (tibia). It stabilizes the knee and minimizes stress across the knee joint.
Nearly 400,000 ACL repair procedures are performed each year in the U.S.1 Though ACL tears are more common in males, young female athletes are up to eight times more likely to tear their ACLs.2
