Patent number: 9532879Abstract: A modular knee prosthesis system includes a femoral component having a stem, a plurality of different sizes of sleeves mountable on the stem, and a plurality of different sizes of augments mountable on the femoral component. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves.Type: GrantFiled: March 15, 2013Date of Patent: January 3, 2017Assignee: DEPUY IRELAND UNLIMITED COMPANYInventors: Jay R.

Patent number: 9144498Abstract: A modular orthopaedic implant system has first, second and third implant components. Two of the components have bores and the third component has a post. The third component can be assembled with either the first or second components with the post received in the respective bore of the other component. When assembled, the length of the post received within the bore of one of the components is greater than the length of the post received within the bore of the other component. The fatigue strength of the assembly with a greater length of the post received within the bore is greater, and this assembly can be used where such greater fatigue strength is needed and the other assembly can be used where a lesser fatigue strength is needed. Since the third component that is used in both assemblies may be the same, inventory may be reduced.Type: GrantFiled: March 15, 2013Date of Patent: September 29, 2015Assignee: DEPUY (IRELAND)Inventors: Michael A. Cook, Filip Leszko, Aaron J Matyas

Patent number: 9138321Abstract: An implantable orthopaedic knee prosthesis assembly includes a femoral component, a stem component, a fastener, and a retention device. The femoral component is configured to be implanted into a distal end of a femur of a patient and includes a stem post having a proximal tapered bore, a distal passageway, and a threaded passageway connecting the proximal tapered bore and the distal passageway. The stem component is configured to taper fit to the femoral component and includes a bore formed therein extending proximally and a threaded aperture defined at a proximal end of the bore. The head of the fastener is configured to be received in the distal passageway, whereas the proximal end of the shaft of the fastener is configured to be positioned in the threaded aperture. The retention device is received in the threaded passageway and prevents the proximal end of the fastener from reentering the threaded passageway.Type: GrantFiled: March 15, 2013Date of Patent: September 22, 2015Assignee: DEPUY (IRELAND)Inventors: Aaron J.
