A prosthetic part (10) for use as an orthopedic im- plant has a base member defining an outer surface (20) for implantation adjacent a prepared bone surface (21). The outer surface (20) includes a recessed area (16) having a predetermined shape and depth. A first rigid plate (22) hav- ing this predetermined shape and having a plurality of el- ongated slots (26) formed therein is fixedly attached within the recessed area (16) of the base member. A second rigid plate (24) also having the same predetermined shape as the recess and also having a plurality of elongated slots (28) formed therein is attached to the first rigid plate. The elon- gated slots (28) of the second plate (24) are angularly offset with respect to the elongated slots (26) in the first plate to produce a controlled porosity. The thicknesses of the first and second plates are predetermined so that the outer sur- face (18) of the second plate is substantially continuous with the non-recessed outer surface (20) of the base mem- ber (10).
