This surgery is to replace a torn anterior cruciate ligament (ACL) a major ligament in your knee. An outpatient procedure that's performed through small incisions around your knee joint. The torn ligament is removed and replaced with a piece of tendon from another part of your knee or from a donor.
This procedure is typically done under general anesthesia. The surgeon will remove your damaged ligament, and then replace it with a segment of the tendon, this replacement tissue is called a graft. The surgeon will drill sockets or tunnels into your thighbone and shinbone to accurately position the graft, which is then secured to your bones with screws or other fixation devices. The graft will serve as scaffolding on which new ligament tissue can grow.
The doctor will give you specific instructions on how to control swelling and pain after surgery, and also specified if you need crutches during the first days. The doctor also may ask you to wear a knee brace or splint to help protect the graft.
