physicians use classification types to assess the degree of injury, treatment plan and predict prognosis. multiple classifications of tibial plateau fractures have been developed. currently, the schatzker classification system is the most widely accepted and used. it is composed of six condyle fracture types classified by fracture pattern and fragment anatomy. each increasing numeric fracture type denotes increasing severity. the severity correlates with the amount of energy imparted to the bone at the time of injury and prognosis.
