Read the full transcript »

The Anterior Cruciate Ligament or ACL is located in the center of the knee along with the Posterior Cruciate Ligament or PCL. These ligaments wrap tightly around the femur and the tibia of the leg to form a crisscross pattern in the knee which prevents the joint from moving too far forward or backward. Injuries to the ACL are usually sports related. However, a torn, stretch or ruptured ACL can also be caused by repetitive physical stress such as excessive pivoting or twisting of the knee. ACL injuries generally cause swelling, stiffness and pain. Many times a noticeable popping noise can be heard at the time the injury occurs.
