ACL Injuries

Monday, February 07, 2011

The anterior cruciate ligament, or ACL, is one of four major knee ligaments. It is critical to knee stability. In todays 60 Second Housecall, Dr. Edward Hill discusses what happens when this ligament is injured.

Dr. Hill:

The anterior cruciate ligament is a band of tissue that keeps the knee joint in place. It connects the femur with the tibia.

Your ACL can tear during a contact or noncontact injury. A contact injury can happen when your leg is firmly planted on the ground and something hits it from either side. Noncontact injuries happen when your knee is extended too far or when it twists too far. Activities with these types of movements include skiing, volleyball, basketball, soccer, football and tennis.

If you hear a popping sound, following by knee pain and swelling, you may have an ACL tear. You might also feel your knee giving out when you try to put weight on that leg. Your doctor will examine your knee to see if the ACL is torn. You may also need an X-ray or other scans.

You may need surgery to repair an ACL tear. During surgery, doctors take tissue from another part of your body to replace the torn ACL.
