1. A method of manufacturing a distal femoral knee prosthesis comprising the steps of:

  • a) forming a rough prosthesis workpiece member that has the approximate size and shape of a final, polished distal femoral prosthesis the workpiece member including a generally "J" shaped articular surface portion to be finished;

    b) attaching the prosthesis member to a fixator;

    c) movably supporting the fixator adjacent a rotary grinder wheel;

    d) controlling relative motion between the rotary grinder and the prosthesis member workpiece with a computer;

    e) shaping a curved articular surface of the prosthesis member by engaging the prosthesis member with the rotary grinder wheel that forms a plurality of grooved portions;

    f) preliminary polishing the articular surface to remove the grooved portions; and

    g) secondarily polishing the articular surface until it has a highly polished mirror finish.
