What is an ACL Injury?
In the U.S. around 200,000 anterior cruciate ligament (ACL) tears occur every year.
If you suddenly and sharply twist your knee, you can sprain or tear the ACL. The injury causes pain and swelling. An unrepaired ACL can allow the shin bone to shift forward, an often painful "popping out" sensation.
A badly torn ACL requires surgery to repair the damage. If the injury is less severe, doctors can treat it with rest, medication and exercise.
Living with an ACL Injury
Your ACL injury may require surgery. Regaining the strength in the affected knee requires both patience and a commitment to recovery. Full recovery may take up to one year. You can expect to participate in formal therapy once or twice a week during the recovery period. However, you will also be given exercises to do on your own. It is important that you do the exercises regularly.
You may experience setbacks during rehabilitation, such as:
- Prolonged pain
- A feeling that your knee is not getting better
If you experience these setbacks, be sure let your doctor know!
Getting a Second Opinion about an ACL Injury
It is important to seek a second opinion if you are not comfortable with the recommended treatment for your ACL injury.

Tests and Treatments
Tests for ACL Injuries
Physical History and Examination. Your doctor will ask what caused your injury. A sudden twist to the knee that causes a pop in the joint and swelling is a good indication of an ACL injury. A physical examination of the knee joint may reveal a “soft end point” that is a sign that solid ligament is missing.
Magnetic Resonance Imaging. A magnetic resonance imaging (MRI) test shows three-dimensional pictures of the ligaments and other tissues in the knee. The MRI confirms an ACL injury.
Treatments for ACL Injuries
If the ACL is stretched or slightly torn, you may be able to heal it without surgery.
Nonsurgical Treatment. Nonsurgical treatment requires:
- Resting, icing and elevating the knee frequently to reduce swelling
- Exercising regularly to increase range of motion, strength and flexibility
Your doctor may also ask you to wear a brace to keep the joint from moving while it heals.
Surgical Treatment. A severe tear of the ACL requires surgery. An ACL injury can usually be repaired using arthroscopic surgery, which creates less scarring than open knee surgery.
This arthrosopic approach requires relatively small incisions, through which your doctor inserts instruments to see inside the knee joint and locate the tear. The repair of the joint is made with small tools inserted through the incisions.
