The anterior cruciate ligament (ACL) is a ligament that can be found in the knee. The ACL attaches two of three bones that link to form the knee joint. These bones are the tibia, which is the larger bone in the calf area, and the femur, which is the bone found in the thigh. The third, non-connected bone is the patella, which is the kneecap that offers protection to the overall area. The knee joint houses four primary ligaments, which are separated into the following two groups. The collateral ligaments, which consist of the lateral collateral ligament (LCL) and the medial collateral ligament (MCL), can be found toward the left and right of the patella. Collateral ligaments regulate sideways movements along with bracing for atypical motions. The cruciate ligaments can be found in the center of the knee and consist of the posterior cruciate ligament (PCL), and the anterior cruciate ligament (ACL.) The cruciate ligaments cross one another with the ACL originating anteriorly (toward the front of the knee.) and the PCL originating posteriorly (toward the back of the knee in back.) The cruciate ligaments regulate the forward and backward movement of the knee, support rotations of the knee, and keep the tibia and femur from moving out of their anatomical location.

Approximately 50% of all injuries about the ACL end up with secondary damage to other structures in the knee, including the meniscus, collateral ligaments, articular cartilage, or cruciate ligaments. Injuries to…
