Abstract

A prosthetic joint and related placement method are provided for cemented fixation to a prepared patient bone, with a cement layer and mantle of controlled, predetermined thickness. The prosthetic component such as a tibial or femoral component for a knee prosthesis includes an attachment surface bounded by a flow restrictor wall which cooperates with the attachment surface to define an open-sided cavity for receiving a quantity of bone cement. An intruder tool is provided to form a shallow recess in the prepared patient bone for mating seated reception of the flow restrictor wall on the prosthetic component. In one form, the prosthetic component and the intruder tool may be adjustable to fit patient bones of different size.
