A method of forming an orthopedic implant having a porous surface layer thereon. A mask includes a cut-out configured to receive a portion of the implant therein. The implant is placed within the cut-out and thereby masked. A water soluble binder solution is sprayed onto at least a part of the unmasked portion of the implant using a sprayer, thereby forming a binder layer on the implant. The binder solution includes water, ethanol, gelatin, glycerin, and a colorant. A porous layer including a plurality of metallic particles is contacted with the binder layer. The porous layer is bonded with the surface of the implant with a sintering process.

A method of making an orthopaedic implant includes the step of forming an orthopaedic implant body which has a supporting surface. A porous metal pad is formed to fit the supporting surface of the body. The porous metal pad is clamped and/or adhesively bonded to the supporting surface. A laser beam is coupled between the porous metal pad and the implant body at a plurality of locations so as to form a coalescence of metal between the porous metal pad and the body.
