ACL, or anterior cruciate ligament, injuries of the knee are common among certain types of athletes, and may require surgery to restore full function of your knee.

An ACL injury occurs when you tear your anterior cruciate ligament, located inside your knee joint. ACL injuries commonly occur due to physical activities requiring quick starts and stops such as in basketball, tennis and volleyball. Warming up and stretching prior to your workout is essential to prevent an ACL injury.

Anterior cruciate ligament, or ACL, injuries affect hundreds of thousands of people in the U.S. every year. Because this ligament is key to the stability of your knee joint, surgery is frequently required to repair severe ACL tears.

The anterior cruciate ligament, or ACL, controls the motion of the shin and thigh bones. ACL tears occur when the knee becomes unstable and buckles. ACL injuries are often the result of sports injuries and are frequently treated with surgery for patients who want to continue to lead an active lifestyle.

Injuries to your anterior cruciate ligament, or ACL, are some of the most devastating injuries in sports. To compound matters, the surgery to fix your ACL is traumatizing as well, with most athletes needed up to a year to fully recover.
