van Kuijk KSR, et al. - Experts contrasted the anteroposterior (AP), lateral, and Rosenberg view radiographs of 94 patients with a ruptured posterior cruciate ligament (PCL) to a control group of 168 patients with an intact PCL following a knee injury in order to recognize any differences in bone morphology that were associated with a PCL. Shape variants on the AP and Rosenberg view radiographs were discovered to be significantly distinctive between patients who tore their PCL and those with an intact PCL following a knee injury. Overall, in comparison with control patients, patients who ruptured their PCL have smaller intercondylar notches and smaller tibial eminences. Hence, it was demonstrated that variations in the shape of the knee are correlated with the presence of a PCL rupture subsequent to the injury. Moreover, a smaller and more sharply angled intercondylar notch and a more flattened tibial eminence are associated with PCL rupture, which implies that the morphology of the knee is a risk factor for maintaining a PCL rupture.
