The ACL is an important anterior stabilizing structure of the knee joint. A rupture can produce significant knee instability and seriously affect knee function. If left untreated, repeated sprains of the joint can easily cause damage to the articular cartilage, meniscus and other important structures, leading to premature aging of the joint and the occurrence of osteoarthrosis. The ACL, also known as the anterior cruciate ligament, is located in the knee joint and connects the femur to the tibia. Its main function is to limit excessive forward displacement of the tibia, and it works together with other structures in the knee joint to maintain the stability of the knee joint and enable the body to perform various complex and difficult lower limb movements. The anatomical and biomechanical characteristics of the ACL have led to different disease characteristics from other knee injuries in terms of population distribution, injury mechanisms, and combined injuries. The literature reports that the incidence of ACL rupture in the general population in the United States is about 1/3000, while the annual incidence of ACL rupture in soccer players is 60/100,000. A census of our active athletes found the incidence of ACL rupture to be 0.43%.
