#$%^&*AU2010236107B220150917.pdf#####ABSTRACT OF THE DISCLOSURE A joint prosthesis system is suitable for cemented fixation. The system has two metal implant components and a bearing. One of the metal implant components has an articulation surface for articulation with the bearing. The other metal implant component has a mounting surface for supporting the bearing. One of the metal implant components includes a solid metal portion and a porous metal portion. The porous metal portion has surfaces with different characteristics, such as roughness, to improve bone fixation, ease removal of the implant component in a revision surgery, reduce soft tissue irritation, improve the strength of a sintered bond between the solid and porous metal portions, or reduce or eliminate the possibility of blood traveling through the porous metal portion into the joint space. A method of making the joint prosthesis is also disclosed. The invention may also be applied to discrete porous metal implant components, such as augment.
