Should I have ACL reconstruction surgery?

A tear in the anterior cruciate ligament (ACL) is one of the most common knee injuries, and causes the knee to become unstable and weak. Recovery from an ACL injury varies from person to person, and not all ACL tears need surgery. Before deciding to have ACL reconstruction surgery, individuals need to consider how it would impact their daily activities, activity level, and livelihood. Patients who experience recurrent episodes of knee instability, expect to return to high-level athletics, or do not want to attempt conservative therapy should consider ACL reconstructive surgery with Long Island orthopedic surgeon and sports medicine specialist Dr. George Ackerman.

How does ACL Reconstruction Surgery work?

Photos below show a torn ACL (left) and the reconstructed ligament from a cadaver allograft (right).


ACL reconstruction surgery generally takes less than an hour, depending on what graft is used. General or regional anesthesia is used for the surgery, and a leg nerve block is also commonly used so that the patient does not experience any immediate post-operative pain. After the new ACL has been placed, the incision is closed and a sterile dressing and brace are applied.

ACL reconstruction surgery is usually not performed until swelling and inflammation have reduced. Unfortunately, the ACL is a unique ligament in that it does not heal when the two torn pieces are surgically stitched together. Therefore, a new ligament must be created from a tissue graft and inserted into the injured knee. In general, there are three main types of ACL grafts: patellar tendon autograft, hamstring autograft, and allograft. Autografts are harvested from your own body using minimally invasive surgical techniques and then inserted into your injured knee using screws. The tissue eventually heals into its new location and becomes a functioning ACL. The process with an allograft is identical, except the tissue comes from a cadaver donor instead of your own body. Deciding what type of graft for a surgery is based on the patient’s age, past medical history, lifestyle, and personal preference. Dr. Ackerman has extensive experience with all types of grafts for ACL reconstruction surgery and revision ACL reconstruction surgery.  He feels it is very important to individualize ACL treatment and is always willing to discuss your preferences.

ACL Reconstruction Results

ACL reconstruction surgery will restore normal or almost normal stability in the knee. It will reduce pain, prevent osteoarthritis, prevent further injury or damage to other knee structures, and restore the level of function the patient had before the injury.

ACL Reconstruction Rehabilitation

Much of the success of ACL reconstructive surgery depends on the patient’s dedication to rigorous physical therapy. The individual’s willingness and ability to complete difficult exercises month in and month out will determine the success of the ACL reconstruction surgery. Patients can expect rehabilitation to continue until the knee is stable and strong, rather than for a limited amount of time.

Hard work and dedication will help reduce knee swelling, maintain mobility of the kneecap, regain full range of motion of the knee, as well as strengthen the quadriceps and hamstring muscles. If you have more questions about ACL recovery, Long Island orthopedic surgeon Dr. Ackerman can help.
