Patent ID: 8206452

Claim:
A prosthetic joint assembly supporting articulation of a joint comprising: a first component configured to be fixed to an anatomical feature, the first component including a first dampening member that defines a first impact surface; and a second component that engages the first component, the second component including a second dampening member that defines a second impact surface that impacts the first impact surface of the first dampening member as the first component moves relative to the second component; the first and second dampening members operable to dampen energy resulting from impact of the first and second impact surfaces, wherein the first component is a femoral component configured to be fixed to a femur, and wherein the second component is a bearing with a bearing surface, the femoral component including an articulating surface that is supported for articulation on the bearing surface of the bearing, the first dampening member having at least one of a lower stiffness and a lower hardness than the articulating surface, the second dampening member having at least one of a lower stiffness and a lower hardness than the bearing surface.
