Anatomy and biomechanics of the ACL

The anterior cruciate ligament is one of a pair of cruciate ligaments in the human knee. They are also termed cruciform ligaments as they are arranged in a traversed formation. In the quadruped stifle joint based on its anatomical position, it is also denoted to as the cranial cruciate ligament.
