The anterior cruciate ligament (ACL) is one of the four main ligaments within the knee that connect the femur to the tibia. The knee is basically a hinged joint that is held together by the medial collateral ligament (MCL), lateral collateral ligament (LCL), posterior cruciate ligament (PCL), and the anterior cruciate ligament (ACL). The ACL runs diagonally in the middle of the knee, preventing the tibia from sliding out in front of the femur, as well as providing rotational stability to the knee. The ACL provides 85% of the restraining force of the knee flexion. An ACL tear usually occurs when the knee is hyperextended and a pivot occurs. This usually involves jumping, cutting, or any sudden movement. ACL tears are very common in sports
