Title:
TIBIAL TRAY PROSTHESIS
Document Type and Number:
WIPO Patent Application WO/2021/233025
Kind Code:
A1
Abstract:
A tibial tray prosthesis (100, 200), having an anteroposterior diameter A and a left-right diameter B. Moreover, the anteroposterior diameter A shows an increasing trend as the left-right diameter B increases, and the ratio A/B of the anteroposterior diameter A to the left-right diameter B shows a decreasing trend as the left-right diameter B increases. The present invention can enable the shape of the tibial tray prosthesis to be closer to the anatomical shape of the tibia of a human knee joint, thereby improving the coverage of a tibial prosthesis, and reducing the probability of prosthesis loosening and postoperative pain in patients.
