Background: the tibia is the major weight-bearing bone of the lower leg. The proximal portion of the bone, the tibial plateau, forms the lower surface of the knee joint and it consists of two condyles – medial and lateral – separated by the tibial spines, The articular surface of the medial plateau is concave, whereas that of the lateral plateau is convex. The knee is a complex dynamic joint that is subjected to many forces during normal activities, so intact articular surface of tibial plateau is one of important factors to keep the geometry and alignment of the knee joint to act in harmony to perform its crucial function as a flexible weight bearing joint. Objective: the aim was to describe the operative procedures and clinical outcomes of internal fixation of tibial plateau to treat comminuted fractures of the tibial plateau according a new three-column classification. Conclusion: using anatomical locking plates on tibial plateau is an effective and safe tool to treat complex three-column fractures of tibial plateau and is more convenient than common plate.
