Less frequently, a cruciate ligament injury involves an avulsion fracture at the origin or insertion of the ligament, usually from the insertion site on the tibial surface. This small fracture is highly correlated with rupture of the anterior cruciate ligament (ACL), and its presence is widely accepted to indicate major internal derangement and possible anterolateral rotational instability of the knee [27-32].
