Abstract
Systems and methods for providing tissue-interfacing surface layers with increased roughness can be attained by providing a metallic powder to a machined or previously machined tissue-interfacing surface of a porous foam structure. The metallic powder can have sizes and characteristics such that the porous structure can have an increased roughness at the tissue-interfacing machined surface while inhibiting the occlusion of the open pores in the porous metallic foam structure.
