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

摘要

PROBLEM TO BE SOLVED: To make a knee prosthesis to include a femoral component, a tibial component, a bearing, and a control arm; and the bearing to be in articular bearing engagement with the femoral component and in sliding and rotational bearing engagement with the tibial component. SOLUTION: Movement of the bearing relative to the tibial component is controlled by a control arm. Anterior and posterior extremes of the control arm include stops for limiting anterior and posterior movement of the bearing relative to the tibial component. At least one of the stops is removable relative to the control arm to facilitate implantation. COPYRIGHT: (C)2005,JPO&NCIPI
