Tibia and femur form the knee joint, of which the surface contact with the femur for tibial plateau. Tibial plateau is an important structure knee load, once the fracture occurs, the inner and outer platform being uneven force, which will produce changes in osteoarthritis. It can be caused by direct violence or indirect violence, and can be divided into the following types:
1.Ⅰ types: simple tibial condyle fracture splitting.
2.Ⅱ type: lateral condyle fracture splitting merged platform collapse.
3.Ⅲ type: Central simple platform collapse fractures.
4.Ⅳ type: medial plateau fractures, can be expressed as the medial condyle fracture or split platform collapse tibia fractures alone.
5.Ⅴ type: tibia, lateral condyle fractures.
6.Ⅵ type: tibial plateau fractures while tibial metaphyseal or tibial shaft fractures.
