Anterior Cruciate Ligament

The anterior cruciate ligament (ACL, commonly referred to just as the cruciate ligament or "lateral Cruciate ligament") is one of the four major ligaments of the knee. It connects from a posterio-lateral part of the femur to an anterio-medial part of the tibia. These attachments allow it to resist anterior translation of the tibia, in relation to the femur. More specifically, it is attached to the depression in front of the intercondyloid eminence of the tibia, being blended with the anterior extremity of the lateral meniscus. It passes up, backward, and laterally, and is fixed into the medial and back part of the lateral condyle of the femur.

Anterior cruciate ligament injury is the most common knee ligament injury.
