Abstract
A knee joint prosthesis with a tibial component, a femoral component and a hinge which connects the two components and defines a pivot axis at a fixed distance from both components. The planes of the axes of shanks of the two components are located at selected distances from each other and from the pivot axis, and the pivot axis is placed nearer to the rear portions than to the front portions of the two components. This reduces the need for resection of affected bones and enhances the transfer of forces as well as the stability of the prosthesis.
