An avulsion fracture of the posterior cruciate ligament (PCL) occurs when the ligament pulls a fragment of bone away from its attachment site rather than tearing through its own substance. It’s a rare injury and is missed most often, particularly when associated with multiple injuries or fractures around the knee and hip. While avulsions can theoretically occur at either the femoral or tibial attachment, the tibial insertion is by far the more commonly affected site and is the focus of most of the clinical literature. This injury pattern is especially frequent in young, active patients and is a classic finding after high-energy trauma such as motor vehicle or motorcycle collisions, falls onto a flexed knee, or sports injuries involving a "dashboard"-type mechanism. Surgical fixation can be achieved either by open or arthroscopic technique but open reduction and internal fixation (ORIF) is the gold standard. There are several studies on surgical fixation of isolated PCL avulsion fractures.
