= Anterior Cruciate Ligament Injury Prevention = Adam Regina Lewis KIN 412 California State Polytechnic University, Pomona

= ACL Prevention Intro = In order to anticipate an injury from occurring it would be most beneficial to understand the mechanics of the injury that way you can prevent it from happening. Anterior cruciate ligament commonly known as ACL tear is known to be a very serious and common sports related injury especially in females. Furthermore, the bulk of these injuries are not contact related but are commonly found in landing situations, quick stops, and quick change of direction. Biomechanically, this injury mainly occurs because of external or internal rotation of the tibia with a valgus collapse close to full knee extension. = ACL Prevention Exercises = Therefore, since we know that females are more prone to sustaining an ACL tear it is beneficial to assume that female kinetics and kinematics are risk factors. Moreover, examining a subject to see if he or she opposes any of the common risk factors would be a start to prevention. This can be done through video taping or if you have the technology motion capture systems are even better. If the subject has risk factors it is imperative to educate them on what movements commonly cause an ACL tear, how they can avoid those dangerous movements, and what they can do to strengthen the weak spots that are prone to failure. Lastly, some exercises should be taught to strengthen the muscles around the subject’s knees. Some common exercises would be hamstring curls, quad sets, bridging, and shallow standing knee bends. These exercises are all easy to learn and should not over stress the knees.
