What is ACL Reconstruction

Anterior cruciate ligament (ACL) reconstruction is a type of surgery that replaces the ligament in the center of the knee. The ACL connects the knee to the shin. A torn or damaged ACL causes the knee to give way during physical activity.

Identification

• Evidence that ACL reconstruction might be necessary is an unstable or painful knee that gives way during activity, especially those involving lateral movement.

Features

• Replacing the damaged ACL requires taking tissue either from the patient, called autograft, or someone who died and donated part or all of their body to medicine. Common areas for autograft donor tissue are knee tendons or the hamstring.

Procedure

• The reconstruction will be done arthroscopically. Several small cuts are made around the knee. A small camera is inserted through one, into the joint, so the surgeon can watch his progress on a monitor.

The Facts

• A tunnel is cut in the bone, where the new tissue is threaded through, then attached to the bone with screws. Healing causes the tunnel to fill in, securing the new ligament even more.

Warning

• It usually takes 5 to 7 months after ACL reconstruction to resume full activity level, especially if one is athletic.
