Anterior Cruciate Ligament Tear or ACL Tear

By: Jon Stiffler, PTA/Sports Center Manager

This injury is a tearing of the ACL ligament in the knee joint. The Anterior Cruciate Ligament is one of the bands of tissue that connects the femur to the tibia. An ACL tear can be painful and it can cause the knee to become unstable.  The ACL is one of the major stabilizing ligaments in the knee. It prevents the tibia (Shin bone) moving abnormally on the femur (thigh bone). When this abnormal movement occurs it is referred to as instability.  The surgical technique for this instability is an ACL reconstruction.
