the knee anatomy provides insight into predicting why certain fracture patterns occur more often than others. the medial plateau is larger and significantly stronger than the lateral pleateau. also, there is a natural valgus or outward angulation alignment to the limb which coupled with the often valgus or outwardly angulating force on impact will injure the lateral side. this explains how 60% of plateau fractures involve the lateral pleateau, 15% medial plateau, 25% bicondylar lesions. partial or complete ligamentous ruptures occur in 15-45%, meniscal lesions in about 5-37% of all tibial plateau fractures.
