ACL reconstruction is surgery to replace the ligament in the center of your knee with a new ligament. The anterior cruciate ligament (ACL) keeps your shin bone (tibia) in place. A tear of this ligament can cause your knee to give way during physical activity.

Anterior cruciate ligament repair

You will probably receive general anesthesia right before surgery. This means you will be unconscious and unable to feel pain. Sometimes, other kinds of anesthesia are used for this surgery.

The tissue that will replace your damaged ACL will come from your own body or from a donor. A donor is a person who has died and, before death, chose to give all or part of their body to help others.

• Tissue taken from your own body is called an autograft. The two most common places to take tissue from are a tendon in your knee or your hamstring. Your hamstring is a tendon behind your knee.
• Tissue taken from a donor is called an allograft.

The procedure is usually done by knee arthroscopy. With arthroscopy, a tiny camera is inserted into the knee through a small incision (cut). The camera is connected to a video monitor in the operating room. Your surgeon will use the camera to check the ligaments and other tissues of your knee.
