Abstract

The present application relates to the field of implanted biomaterials, in particular to a total knee joint prosthesis for unicondylar postoperative revision, including a tibial plateau and a tibial pad installed on the tibial plateau, the tibial plateau includes a mounting platform and The installation column fixed on one side of the installation platform, the thickness of the one side of the installation platform is greater than the thickness of the other side of the installation platform, and the side of the installation platform facing the installation column is at the center of the installation column A stepped surface is formed. The application has the effect of reducing the pain of patients during revision after unicondylar surgery and shortening the operation time.

Description

technical field [0001] The present application relates to the field of implantation of interventional biomaterials, in particular to a total knee joint prosthesis for revision after unicondylar surgery. Background technique [0002] A unicondylar knee prosthesis is a surgical implant used to replace the knee joint for unicondylar knee replacement surgery. In unicondylar knee surgery, the upper side of the tibia and the lower side of the femur need to be resected, and half of the resected side is the side where the unicondylar knee prosthesis needs to be implanted to accommodate the unicondylar knee joint Prosthesis. [0003] However, when the unicondylar knee joint is revised and changed to total knee joint replacement, the upper side of the tibia and the other half of the lower side of the femur need to be resected, and the tibial plateau after this resection and the one after the unicondylar surgical resection need to be maintained. The tibial plateau is flush. The curr...
