Abstract
A posterior stabilized knee prosthesis with removable pin in the femoral component. The removable pin has a tapered split ring lock which prevents the pin from backing out. A split ring is provided on the pin which rides in a groove on the pin. When the pin is properly seated, the split ring engages a corresponding groove within the femoral prosthesis, locking the pin in place. Chamfers are provided on both the front and back of the split ring so that the split ring will compress as the pin is being screwed into the femoral component and also so that the pin can be removed if necessary.
