Anterior cruciate ligament or ACL injury is one of the common types of knee injury among sports injuries. An anterior cruciate ligament is a strong band of tissue connecting the femur and tibia. Anterior cruciate ligament injuries can occur during physical activities, sports, or any accident that puts pressure on the knee joint. Sudden slow down or direction change during running, pivoting with foot firm on a position, landing awkwardly during a jump can cause ACL tear or torn ACL.
