Abstract

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.

Description

[0001] Related Patent Applications [0002] This patent application is a continuation-in-part of the following U.S. patent application, the disclosure of which is incorporated herein by reference in its entirety: U.S. Patent Application No. 12, entitled "Implants with Roughened Surfaces" / 470,397 (Attorney Docket No. DEP6089USNP), and claims priority to U.S. Provisional Patent Application No. 61 / 256,468, filed October 30, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to implantable orthopedic prostheses, and more particularly, to implantable prostheses having bearing assemblies and other components for supporting the bearing assemblies. Background technique [0004] During the patient's lifetime, the patient may require joint replacement surgery due to, for example, disease or trauma. Joint replacement surgery may involve the use of a prosthesis that is implanted in one or more of the patie...
