Comminuted tibial plateau fracture collapse is a serious fracture, often accompanied by ligament, meniscus and other injuries, the later occurrence of traumatic arthritis may be greater. 1. Tibial plateau comminuted fracture collapse affects the knee joint surface, which is an unstable fracture, caused by moderate to high energy violence, often with joint instability, combined with serious injuries to the soft tissues of the knee (anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, meniscus), osteo-fascial compartment syndrome, deep vein thrombosis, and serious neurovascular injuries, which requires bone grafting and strong internal fixation of the steel plate. 2. As there are often combined injuries, osteofascial compartment syndrome, deep vein thrombosis, and vascular injuries may cause necrosis of the lower limb, and slow recovery after repair of nerve injuries. Fractures of the tibial plateau affect the cartilage damage of the knee joint surface, even if the fracture heals, the cartilage can not be repaired or mildly recovered, postoperative traumatic arthritis occurs, and may be early for joint replacement. Comminuted fracture collapse of the tibial plateau requires aggressive surgery and postoperative physician-directed rehabilitation.
