Exemplary representation of the Injury severity to the posterolateral tibial plateau. Sequential sagittal (a, b, c) fat-suppressed proton density-weighted magnetic imaging depicting the posterolateral aspect of the knee joint. In a there is no edema/no fracture caused in the event of an ACL rupture. b shows an edema of the PLTP with concomitant edema of the lateral femoral condyle (Indicated by the white arrow. In figure c we see a posterolateral fracture (2b according to Bernholt et al. [24]) with an indicated associated edema of the lateral femoral condyle (White arrow). The solid line indicates the physiological joint line. The dashed lines represent the impression fragment
