Anterior Cruciate Ligament Injury (ACL Injury): Causes
Pronounced: an-TEER-ee-or KROO-shee-ate ligamentEn Español (Spanish Version)
An anterior cruciate ligament (ACL) injury is a tear in the ACL ligament. The ACL is located in the middle of the knee joint. It connects the lower leg bone to the thigh bone. It stabilizes the knee and prevents the lower leg bone from sliding too far forward at the knee.
The ACL ligament can become strained or torn when a strong force is applied to it. This can happen during sports or other high-stress activity.
Treatment depends on the severity of the injury.
