Abstract
A method of forming a porous matrix and a porous matrix having a uniform surface, depth and a controlled microstructure is provided. The uniform matrix to provide for fixation of prosthetic device by tissue ingrowth is formed through the action of heat and pressure in a hot isostatic pressing process. Such a process provides a porous matrix having a uniform surface and depth due to the isostatic pressure applied and a controlled microstructure of the material due to the relatively low temperatures employed.
