  • Prosthetic knee with removable stop pin for limiting anterior sliding movement of bearing
    Patent number: 7014660
    Abstract: 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.
    Type: Grant
    Filed: April 9, 2003
    Date of Patent: March 21, 2006
    Assignee: Biomedical Engineering Trust I
    Inventors: John B. Fenning, Michael J. Pappas
  • Prosthetic knee with removable stop pin for limiting anterior sliding movement of bearing
    Patent number: 7008454
    Abstract: 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. 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.
