The anterior cruciate ligament (ACL) connects your shin bone (tibia) to your thigh bone (femur). A tear of this ligament can cause your knee to give way during physical activity, most often during side-step or cutting movements.Related video goes here for no-HTML5 browsers Description Most people have general anesthesia for this surgery.

A donor is a person who has died and chose to give all or part of their body to help others.Tissue taken from your own body is called an autograft. The most common places to take tissue from are the knee cap tendon, quadriceps tendon, or hamstring tendon. Your hamstrings are the muscles behind your knee.

Your surgeon will fix any other damage found, and then will replace your ACL by following these steps:The torn ligament will be removed with a shaver or other instruments. If your own tissue is being used to make your new ACL, your surgeon will make a larger cut. Then, the autograft will be removed through this cut. Your surgeon will make tunnels and sockets in your bone through which to bring the new tissue. This new tissue will be put at the same place as your old ACL. Your surgeon will attach the new ligament to the bone with screws or other devices to hold it in place. As it heals, the graft will remodel to become your new ligament.At the end of the surgery, your surgeon will close your cuts with sutures (stitches) and cover the area with a dressing. You may be able to view pictures after the procedure of what the surgeon saw and what was done during the surgery. Why the Procedure Is Performed If you do not have your torn ACL reconstructed, your knee may continue to be unstable. This increases the chance you may have a meniscus tear.
