Anterior cruciate ligament

Type of cruciate ligament in the human knee

The anterior cruciate ligament (ACL) is one of the cruciate ligaments in the human knee. The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (homologous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament.
