Anterior cruciate ligament injury (illustrations)

Case contributed by Matt Skalski
Diagnosis not applicable

This diagram demonstrates a complete ACL tear (figure 1) and ACL avulsion (figure 2) with the arrows indicating the "pivot-shift" twisting mechanism of the knee. Under stress, (classically with athletic activity) this motion may result in an ACL tear. In children, avulsion fracture of the tibial insertion of the ACL is not uncommon.
