The non-rotating tibial insert and the rotating tibial insert are selectively coupleable to the tibial tray such that a fixed or a mobile orthopaedic prosthesis may be configured. In some embodiments, the tibial tray may be a fixed or mobile tibial tray. Additionally, in some embodiments, the prosthetic knee system may include a femoral component.Type: GrantFiled: May 12, 2010Date of Patent: January 31, 2012Assignee: DePuy Products, Inc.Inventors: Gary D.

Patent number: 8100982Abstract: A modular implant system includes a set of anatomically-designed diaphyseal fitting and filling modular implant components and collars. The diaphyseal component connects with a selected intramedullary stem and with a selected collar component. The collar component connects to another implant component such as a modular articular component, a segmental component or an intercalary component. The diaphyseal component has a tapered porous surface that is received with a tapered bore in the bone diaphysis that is prepared to match the size and shape of the tapered porous surface. The collar component has a porous surface for tissue ingrowth, such as the periosteum, to seal the intramedullary canal. The diaphyseal implant is easy to insert and remove, does not bind before fully seating to prevent stress shielding, and eliminates the long lever arm created when fixation occurs only at the tip of the stem, and should eliminate related stem loosening.Type: GrantFiled: December 14, 2005Date of Patent: January 24, 2012Assignee: Depuy Products, Inc.Inventors: Robert K. Heck, Stephen A. Hazebrouck

Each of the mobile inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the mobile tibial components. Each of the fixed inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the fixed tibial components.Type: ApplicationFiled: January 21, 2010Publication date: July 21, 2011Applicant: DEPUY PRODUCTS, INC.Inventors: DANIEL D.

Patent number: 7867282Abstract: A modular implant system includes a set of anatomically-designed diaphyseal fitting and filling modular implant components and adapters for connection to another implant component such as a modular articular component, a segmental component or an intercalary component. The other end of each diaphyseal component is a tapered porous surface. The tapered porous surface is received with a tapered bore in the bone diaphysis that is prepared to match the size and shape of the tapered porous surface. The diaphyseal implant is easy to insert and remove, does not bind before fully seating, and is designed to prevent stress shielding. The diaphyseal sleeve eliminates the long lever arm created when fixation occurs only at the tip of the stem, and should therefore eliminate related stem loosening.Type: GrantFiled: December 14, 2005Date of Patent: January 11, 2011Assignee: Depuy Products, Inc.Inventors: Robert K. Heck, Stephen A. Hazebrouck

Patent number: 7799085Abstract: A modular knee implant system allows a surgeon to select between several different styles of distal femoral implant components and several different styles of stem extensions while also allowing for use of a metaphyseal component. The metaphyseal component can be a universal one that is usable with all of the styles of distal femoral implant components through use of an adapter. A second adapter allows for use of stem extensions with different types of connectors with the metaphyseal component. A separate metaphyseal component could also be provided with a distal Morse taper post to mate with a distal femoral component having a proximal Morse taper bore. The metaphyseal component may have an outer surface that is configured to maximize contact area with the patient's bone, and may have a surface finish over a substantial part of its overall length that is conducive to bone ingrowth.Type: GrantFiled: April 2, 2004Date of Patent: September 21, 2010Assignee: Depuy Products, Inc.Inventors: Gary P. Goodfried, Stephen A. Hazebrouck, Mark B. Lester, Scott C. Brown

Patent number: 7431723Abstract: A tool, system and method for separating connected orthopaedic components are disclosed. The system includes two orthopaedic components that are connected end to end. One of the orthopaedic components has a notch that receives a cam carried by the tool. The notch and cam are sized and shaped so that when the cam is turned, the cam forces the two components apart. The invention is particularly useful when Morse tapers are used to connect the components. The invention can be used with the modular orthopaedic implants as well as with modular trials used intraoperatively. The cam can be removably mounted on the tool.Type: GrantFiled: June 16, 2004Date of Patent: October 7, 2008Assignee: Depuy Products, Inc.Inventor: Stephen A. Hazebrouck
