Abstract
Official abstract text for this publication.
A joint prosthesis system is suitable for cementless fixation. The system includes a metal implant component that has a mounting surface for supporting an insert. The metal implant component 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An orthopaedic prosthetic component, comprising: a polymer modular tibial bearing component, and a tibial tray component configured to be implanted into a proximal end of a patient's tibia and assembled with the modular tibial bearing intraoperatively, the tibial tray comprising: a solid metal portion including a proximal-facing surface configured to receive the modular tibial bearing component, a single, integral metal portion including a porous…
