Patent ID: 8506640

Claim:
A prosthesis, comprising: a femoral component, wherein the femoral component comprises a first condyle and a second condyle, wherein the first condyle and the second condyle are disposed apart from one another such that there is a space between the first condyle and the second condyle, wherein the first condyle comprises at least a first surface generally facing the second condyle across the space between the first condyle and the second condyle and wherein the second condyle comprises at least a second surface generally facing the first condyle across the space between the first condyle and the second condyle; a first attachment mechanism associated with the first surface of the first condyle; a second attachment mechanism associated with the second surface of the second condyle; and a modular stabilizing mechanism, wherein the modular stabilizing mechanism comprises a third attachment mechanism and a fourth attachment mechanism; wherein the modular stabilizing mechanism is configured to permanently attach in a non-reversible manner to the first condyle of the femoral component via a mating between the first attachment mechanism associated with the first surface of the first condyle and the third attachment mechanism of the modular stabilizing mechanism; wherein the modular stabilizing mechanism is configured to permanently attach in a non-reversible manner to the second condyle of the femoral component via a mating between the second attachment mechanism associated with the second surface of the second condyle and the fourth attachment mechanism of the modular stabilizing mechanism; and wherein the modular stabilizing mechanism is attached to the first condyle and the second condyle of the femoral component from a position in the space between the first condyle and the second condyle.
