Closed tibial plateau fracture can be treated by conservative treatment and surgery. 1. Conservative treatment: For simple fracture without obvious displacement, patients can be fixed with cast or brace for about 4 weeks, patients should pay attention to braking, full rest, the best lower limbs should be put flat and straight, and avoid weight bearing on the ground during the period of cast fixation, when conservative treatment is ineffective, surgery should be carried out in a timely manner. 2. Surgery: Due to the complex anatomy of tibial plateau, for tibial plateau fracture with fracture displacement and articular surface collapse, surgery should be carried out. After surgery, the patient should actively cooperate with the doctor to carry out rehabilitation therapy to promote the healing of fracture and prevent the adhesion of the joint. Closed tibial plateau fracture should go to the hospital for examination in time, and the doctor will clarify the degree of injury and choose the appropriate treatment.
