What Is ACL Surgery?

ACL surgery, or surgery of the anterior cruciate ligament, can be performed to repair a torn ligament or for reconstruction.

Injury

• The anterior cruciate ligament connects the femur to the tibia and runs through the center of the knee joint. It is the main stabilizing ligament of the knee, and is torn or injured when rapidly changing direction or decelerating.

Risks & Rewards

• Successful recovery would mean returning to normal level of activity prior to the injury. As with all surgery, patients must deal with the risks of infection, scarring and anesthesia.

Procedure

• The surgery is performed by harvesting a portion of the patellar tendon to replace the torn ACL. The new ligament is fastened with medical or bioabsorbant screws to the tibia and femur.

Arthroscopic

• Most ACL injuries require arthroscopic surgery, when tiny instruments, including a camera, are inserted into the knee via small incisions. This less invasive procedure is considered less risky for orthopaedic surgeons and has benefits for the patient.

Recovery

• Depending on the severity of the injury, recovery may take four to six months of physical therapy and limited motion. Severe cases may take up to one year.

Success Rate

• In 80 to 90 percent of ACL surgeries, patients experienced reduced pain, and increased stability and functionality. Sixty percent of patients return to their full previous level of activity.
