Problems solved by technology

[0003] Prosthesis loosening and postoperative pain are the main reasons for revision of unicompartmental knee arthroplasty, and poor prosthesis coverage is an important reason for prosthesis loosening and postoperative pain. Poor prosthesis coverage means that the prosthesis cannot fully cover the cortical bone area , so that the prosthesis is not well supported, it is easy to cause the prosthesis to sink and loosen after the operation, and the prosthesis protrudes outward, interfering with the surrounding soft tissue, and causing postoperative pain

Abstract

The invention relates to a tibial tray prosthesis. The tibial tray prosthesis is characterized by comprising a front-rear diameter A and a left-right diameter B, wherein the front-rear diameter A is in an increasing trend along with the increase of the left-right diameter B, and the ratio A / B of the front-rear diameter A to the left-right diameter B is in a decreasing trend along with the increase of the left-right diameter B. The tibial tray prosthesis can be closer to the anatomical shape of the knee tibia of the human body, so that the coverage rate of the tibial tray prosthesis is increased, and the probability of prosthesis loosening and postoperative pain of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tibial tray prosthesis. Background technique [0002] Unicompartmental replacement uses a minimally invasive incision while preserving the anterior and posterior cruciate ligaments of the knee joint. It has the advantages of less trauma, faster recovery, and better postoperative physiological activity. Therefore, unicompartmental replacement is widely used in unicompartmental surgery. In the treatment of osteoarthritis. The unicondylar prosthesis used in unicompartmental replacement can be divided into medial femoral prosthesis and medial tibial prosthesis used to replace the medial compartment, and lateral femoral prosthesis and lateral tibial prosthesis used to replace the lateral compartment. [0003] Prosthesis loosening and postoperative pain are the main reasons for revision of unicompartmental knee arthroplasty, and poor prosthesis coverage is an important r...
