Abstract:
1. An implantable orthopaedic knee prosthesis assembly, comprising: a femoral component configured to be implanted into a distal end of a femur of a patient, the femoral component including (i) a bearing surface having a medial condyle surface and a lateral condyle surface, (ii) a backside surface opposite the bearing surface, and (iii) a stem post extending superiorly away from the backside surface along an axis, the stem post having a proximal tapered bore, a distal passageway, and a threaded passageway connecting the proximal tapered bore and the distal passageway, a stem component including a tapered post configured to be received in the tapered bore of the femoral component, the tapered post having (i) a bore formed therein extending proximally along the axis and (ii) a threaded aperture defined at a proximal end of the bore, a fastener comprising (i) a head configured to be received in the distal passageway and (ii) an elongated shaft having a proximal end configured to be positioned in the threaded aperture, and a retention device configured to be received in the threaded passageway to prevent the proximal end of the fastener from backing out of the threaded passageway, wherein the head of the fastener has a diameter larger than a diameter of the threaded passageway and the elongated shaft has a diameter less than the diameter of the threaded passageway.
