Abstract: Objective To explore clinical effect of double plates in the treatment of com-minuted fracture of tibial plateau.Methods Patients with double plates in the treatment of com-minuted fracture of tibial plateau were systematically analyzed.Bone grafting was applied to the area of cancellous bone defect under cartilage surface.The T-shaped supported plate was placed in medial tibial condyle after pre-bending and the lateral was fixed by the small anti-slip plate.And functional exercise of knees after operation was taken.Results All patients were healed and there were no knee valgus deformity,break of plate and screw,deep infection,internal and external fix-ation failures after the operation.The excellence rate reached to 84.2%.Conclusion From the clinical perspective,double plates could effectively treat comminuted fracture of tibial plateau.
