From: Magnetic resonance evaluation in long term follow up of operated lateral tibial plateau fractures
Method of measurements on plain radiograph anteroposterior (right knee – unaffected side): line 1 was drawn between the cortices of the medial and lateral condyle near the articular surface, line 2 was drawn from medial to lateral rim of the proximal tibia (without osteophytes). Tibial widening was given as the quotient of these two parameters and expressed as a percentage of the femoral width
