ports participation results in 70 percent
of anterior cruciate ligament (ACL) tears and the majority of these occur in 15 to 45 year olds. Approximately 70 percent of ACL injuries are noncontact injuries that occur during a sudden
change in direction with a planted foot (i.e., cutting) or stopping rapidly. In the United States there are between 100,000 to 250,000 ACL ruptures annually.
The ACL is one of the main stabilizing ligaments of the knee and helps provide the hinge that allows the knee to remain stable while moving. When an ACL tear occurs the athlete often reports
hearing a pop and usually cannot walk on the injured limb. During the injury it is common for the knee to partially dislocate, resulting in bruising and sometimes a small fracture at the
back of the tibia and on the femur. Also common is a sprain of the medial collateral ligament (MCL) which is located on the inside of the knee. These injuries result in a painful swollen
knee that is tender outside and deep within the knee
Female athletes are two to eight times more likely to rupture their ACL than male athletes. This is primarily due to mechanical reasons, such as weaker core muscles and hamstrings. Another
factor that can increase the risk of ligament rupture is the interface between the player's shoes and the playing surface that results in higher friction. For example, longer
cleats or more cleats on a shoe resulting in better traction and more friction. High risk sports include soccer, basketball, volleyball, skiing, and football.
