| 20110029092 | PROSTHESIS WITH SURFACES HAVING DIFFERENT TEXTURES AND METHOD OF MAKING THE PROSTHESIS - 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. | 02-03-2011 |

| 20100114323 | KNEE PROSTHESIS KIT WITH WINGED SLEEVES AND MILLING GUIDE - A knee prosthesis kit includes single-winged and double-winged metaphyseal sleeve components. A milling guide and reamers in the kit allow for a cavity to be prepared to receive the metaphyseal sleeve components by pivoting one of the reamers on a portion of the milling guide. The instruments allow the cavity to be aligned with the intramedullary canal regardless of the relative hardness of the bone in the vicinity of the cavity. | 05-06-2010 |
