PROSTHETIC KNEE WITH REMOVABLE STOP PIN FOR LIMITING ANTERIOR SLIDING MOVEMENT OF BEARING

摘要

A knee prosthesis includes a femoral component, a tibial component, a bearing and a control arm. The bearing is in articular bearing engagement with the femoral component and in sliding and rotational bearing engagement with the tibial component. Movement of the bearing relative to the tibial component is controlled by a control arm. The anterior extreme of the control arm includes a removable stop for limiting anterior movement of the bearing relative to the tibial component.
