ABSTRACT:
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.
