Anterior cruciate ligament
(ACL) repair is done to reconstruct the ACL in the knee after it is torn. Often, a graft made of tendon is used to reconstruct the torn ligament.
ACL surgery is an elective procedure. This means that surgery is not always necessary; it may depend on your lifestyle and age.
Surgery may be recommended if you have:
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:

You may need to stop taking some medications up to one week before the surgery. Medications that may need to be stopped may include:
Do not eat or drink anything after midnight the day before your surgery, unless told otherwise by your doctor.
Anesthesia will block pain and keep you comfortable during the procedure. Anesthesia methods include:
IVs will be placed in your arm or hands for medications and fluids. The doctor will examine the range of motion of the knee and confirm the ACL tear. Next, the doctor will locate another tendon in your knee or hamstring (called autograft) to reconstruct the torn ligament. Sometimes a donor graft (called allograft) is used. The doctor will form the graft tendon to the correct size.
One or two small keyhole incisions will be made on the top of the knee. An arthroscope (or endoscope) and tiny tools will be inserted into the knee joint. The torn ACL is removed and other damage to the knee is trimmed or repaired. In order to reconstruct the tendon, the doctor will drill holes through bone structures in the thigh and shin. The new graft will be placed through these holes. Needles may be threaded through the holes to suture the new tendon into place. Other devices, such as screws, washers, or staples are also used to hold the graft in place.
Once the graft is securely in place, the doctor will test the knee’s range of motion. Other tests will be done as well. The skin will be closed with stitches. Bandages and/or a brace will be placed on the knee.
About two hours.
Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.
