Document Type and Number:
WIPO Patent Application WO/2021/233023
Kind Code:
A1
Abstract:
Disclosed are a unicompartmental femoral prosthesis system and a unicompartmental femoral prosthesis. The unicompartmental femoral prosthesis system comprises N unicompartmental femoral prostheses gradually increasing in size, wherein N ≥ 2, and the ratio (AP/H) of the anteroposterior diameter (AP) of each unicompartmental femoral prosthesis to the posterior condylar height (H) of the unicompartmental femoral prosthesis increases as the size of the unicompartmental femoral prosthesis increases. The anteroposterior diameter (AP) is the maximum length of the unicompartmental femoral prosthesis in the horizontal direction, and the posterior condylar height (H) is the maximum height of the unicompartmental femoral prosthesis in the vertical direction. The unicompartmental femoral prosthesis system better conforms to the human anatomical structure, and can reduce the problems of insufficient coverage and instability of the distal femur or a posterior femoral condyle, reducing the risk of postoperative pain of a patient.
