ABSTRACT:
A retrofit posterior stabilizing housing is disposed in a resected receptacle in the trochlear groove of a human femur during revision surgery through the intercondylar notch of a previously implanted condylar-type femoral prosthetic component. The posterior stabilizing housing is dimensioned to pass through the notch in the existing implant and seat superiorly to the trochlear opening of the notch. The posterior stabilizing housing includes medial and lateral side walls extending from a proximal ceiling portion, and anterior and posterior end walls disposed between the side walls, defining a box-like container. An aperture is formed in each of the side walls for receiving screw-like fasteners anchored in the cancellous bone portion of the femur. A pair of anchor posts extend superiorly from the ceiling portion for fixation within the femur. The posterior stabilizing housing may either be cemented in place or the superior surface thereof textured to enhance bone ingrowth.
