Abstract

An orthopaedic prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The tibial bearing and the femoral component are configured to promote outward axial rotation of the femoral component on the tibial component during knee flexion.

Description

[0001] Cross-References to U.S. Applications [0002] Cross Reference Application No. XX / XXX,XXX, entitled "Orthopedic Knee Prosthesis with Increased Axial Rotation," Applicant Shouchen Dun, U.S. Patent Application, filed June 30, 2008, in its entirety Incorporated herein by reference. technical field [0003] The present invention relates to an orthopedic prosthesis, in particular to a posterior-stabilized orthopedic prosthesis for knee joint replacement surgery. Background technique [0004] Joint replacement is a well-known surgical procedure in which a diseased and / or damaged natural joint is replaced with a prosthetic joint. A typical knee prosthesis includes a tibial tray, a femoral component, and a polymeric insert or bearing positioned between the tibial tray and the femoral component. Knee prostheses are usually designed to mimic the natural motion of the patient's joint. However, orthopedic prostheses of varying flexibility are used depending on the severity of ...
