From: Magnetic resonance evaluation in long term follow up of operated lateral tibial plateau fractures
Method of measurements on plain radiograph anteroposterior (left knee – affected side): Lateral plateau impression is the difference between line (b) drawn from the maximum impression of tibial plateau baseline parallel to line (c) that is drawn in extension of the medial plateau parallel to the joint line. Line (a) is the common perpendicular to lines (b) and c. There was valgus alignment of the knee joint (not shown)
