Abstract
The invention provides a method of providing a metallic orthopaedic implant with a micron or nanometer-scale surface roughness to facilitate acceptance of tissue and bone growth or apposition after implantation while maintaining the structural integrity of the orthopaedic implant. The invention also provides a metallic orthopaedic implant comprising a metallic body and metallic elements adhered to a portion of the surface of the metallic body to define a three-dimensional porous surface geometry, wherein at least some of the metallic elements have a micron or nanometer-scale surface roughness.
