How is ACL surgery done? Ginni Luthra Asked: September 25, 2020In: ACL-Tear Tear in the anterior cruciate ligament is known as ACL tear. It is one of the major ligaments in the knee. During the ACL reconstruction surgery, the surgeon operates and removes the injured ligament and replaces it with a segment of tendon tissue. The tendon tissue works similarly to that of a ligament which connects the muscle to bone. The surgeon will use a piece of tendon from another part of the knee or a tendon from a deceased donor. After the surgery, the patient can resume a rehabilitative therapy course for recovery. September 25, 2020 Pristyn Care 0 people found this helpful Was this answer helpful?
