ABSTRACT:
A method for fabricating a ceramic prosthesis of high aluminum oxide suite for the tibial plateau of a knee joint with the superior (upper) portion of the prosthesis being of a high density Al.sub.2 O.sub.3 having a very low porosity and the inferior (lower) portion being of high density Al.sub.2 O.sub.3 having a high degree of porosity capable of accepting bone growth. The method of fabricating the prosthesis comprises mixing a powdered batch of high aluminum oxide material to produce a viscous slip, adding a foaming agent to the slip, adding a catalyst to the slip to decompose the foaming agent, infiltrating the slip into a sponge, drying the composite, producing a planar surface on the porous layer, fabricating a second denser layer, placing a slurry between the two layers, drying and sintering the laminate.
