The anterior cruciate ligament (ACL) rupture is the most common serious injury of the knee. It is widely believed that knee injury with associated ACL tear may lead to functional instability. In the active sporting population, such instability has been found to be associated with muscle weakness, meniscal and chondral injuries as well as with the development of degenerative disease within the joint. The goals of ACL reconstruction are to decrease symptoms, improve function, and return patients to their pre-injury level of activity in the short term. ACL reconstruction is a common procedure that usually allows predictable and timely return to function for the patient.
