The anterior cruciate ligament (ACL) is one of the most common ligaments to be injured. The ACL is often stretched and/or torn during a sudden twisting motion (when the feet stay planted one way, but the knees turn the other way). Skiing, basketball, and football are sports that have a higher risk of ACL injuries.
The ligaments are what connect your thigh bone to your lower leg bones. They hold your bones together and keep the knee stable. Knee ligament sprains and tears are very common sports injuries, and can occur to the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and medial collateral ligament (MCL).
