1. A surgical implant device, comprising:
a metallic implant body;
a porous layer with an external layer that is microtextured and that approximates a scanned three-dimensional spongy bone surface, said porous layer is formed on the metallic implant body, wherein the porous layer comprises an irregular lattice of intersecting struts having randomized struct intersection locations and strut cross-sectional diameters; and
a plurality of needle structures having an external surface that is microtextured and protruding from the porous layer opposite the metallic implant body integrally formed by an additive manufacturing process, wherein at least some of the plurality of needle structures are longer and traverse through the porous layer and are coupled directly to the metallic implant body and at least some of the plurality of needle structures are shorter and are coupled directly only to the porous layer and not to the metallic implant body, and wherein the plurality of needle structures increase the coefficient of friction of an exterior surface of the surgical implant device.
