The diagram outlines the anatomical landmarks that delineate the medial, lateral, and posterior columns of the tibial plateau, including their subdivisions of anteromedial, anterolateral, posteromedial, and posterolateral. An axial CT image shows the top view of the tibial plateau, labeling landmarks like the intercondylar eminence, anterior tibial tuberosity, posteromedial ridge, fibular head, and posterior sulcus of the tibial plateau. The dotted line indicates the border between the posterolateral and posteromedial subdivisions and solid lines denote the column borders.

1. Figure 2: Diagram of the tibial plateau outlines the anatomic landmarks that delineate the medial, lateral, and posterior columns, as well as the subdivisions of each column,
including anteromedial, anterolateral, posteromedial, and posterolateral. Axial 3D volume-rendered CT image shows the tibial plateau viewed from above, including the
center of the intercondylar eminence (O), anterior tibial tuberosity (A), posteromedial ridge of the proximal tibia (D), the most anterior point of the fibular head (C), and
posterior sulcus of the tibial plateau (B). Dotted line = border between posterolateral and posteromedial subdivisions, solid lines = column borders.
