Publication number: 20110125283Abstract: Knee prostheses featuring components 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 at least accommodating internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. In a preferred embodiment, such prostheses include an insert component disposed between a femoral component and a tibial component, the insert component preferably featuring among other things a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes.Type: ApplicationFiled: November 23, 2010Publication date: May 26, 2011Inventors: JASON k. OTTO, Brian McKinnon, Dean Hughes, Michael Ries, Jan Victor, Johan Bellemans, Jonathan Garino, Timothy Wilton

Patent number: 7922771Abstract: Knee prostheses featuring components 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 at least accommodating internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. Surfaces can be specially 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: GrantFiled: January 31, 2008Date of Patent: April 12, 2011Assignees: Smith & Nephew, Inc., The Trustees of the University of PennsylvaniaInventors: Jason K.
