Patent number: 9532788Abstract: A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.Type: GrantFiled: May 12, 2015Date of Patent: January 3, 2017Assignee: Smith & Nephew, Inc.Inventors: Jason Sean Jordan, Michael Dean Hughes, Mark Ellsworth Nadzadi, Brian William McKinnon, Paul Charles Crabtree, Jr., David Timothy Mehl

Publication number: 20160310283Abstract: Knee prostheses that more faithfully replicate the structure and function of the human knee joint in order to provide, among other benefits: greater flexion of the knee in a more natural way by promoting or accommodating internal tibial rotation, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a natural way. Such prostheses may include an insert component disposed between a femoral component and a tibial component, the insert component featuring, among other things, a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes. Other surfaces can be shaped using iterative automated techniques that allow testing and iterative design taking into account a manageable set of major forces acting on the knee during normal functioning, together with information that is known about natural knee joint kinetics and kinematics.Type: ApplicationFiled: July 6, 2016Publication date: October 27, 2016Inventors: Jason K. Otto, Brian William McKinnon, Michael Dean Hughes, Michael D. Ries, Jan Victor, Johan Bellemans, Jonathan Garino, Timothy Wilton
