The MSTS functional scores of all different items 4 years after the operations were above 3, which showed the clinical results were satisfactory.</p><p><b>CONCLUSIONS</b>It is an efficacious method for the treatment of malignant tumor of the proximal tibia by using rotating hinge prosthesis. It has the advantage of early recovery of joint function.</p>
