Patent number: 11369477Abstract: 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: GrantFiled: October 11, 2018Date of Patent: June 28, 2022Assignees: Smith & Nephew, Inc., The Trustees of the University of PennsylvaniaInventors: Jason K. Otto, Brian William McKinnon, Michael Dean Hughes, Michael D. Ries, Jan Victor, Johan Bellemans, Jonathan Garino, Timothy Wilton

Patent number: 9848896Abstract: A femoral sizing jig for use in total arthroplasty of left and right knees, comprises a femoral body, an external-rotation-angle arm which is, preferably pivotable, relative to the femoral body for setting an external angular rotation of a left or right femur, at least one of a cutting-jig guide and a cutting jig which is, preferably slidable, relative to the femoral body and in unison with movement of the external rotation-angle arm, and a medial posterior-condylar locator which is movable in unison with the movement of the external-rotation-angle arm, so as to maintain a fixed or substantially fixed relative distance with a medial side of the at least one of a cutting-jig guide and a cutting jig. A posterior-referencing femur resecting system using said femoral sizing jig and a method of resecting a femur at a knee joint relative to the medial posterior condyle are also provided.Type: GrantFiled: October 19, 2012Date of Patent: December 26, 2017Assignee: CORIN LIMITEDInventors: Ian James Emslie, Johan Bellemans, Jan Maria Karel Victor

Publication number: 20150238202Abstract: Leg alignment apparatus for use in total arthroplasty of left and right knees, comprises an intramedullary rod, a femoral body for location on or adjacent to an anterior surface of a femur, and a support element which extends or is extendable from the femoral body to the intramedullary rod for holding the femoral body stationary or substantially stationary relative to the intramedullary rod. A condylar locator which is pivotable relative to the femoral body and which is seatable on a distal end of the femur is also provided, along with a soft-tissue tensioning element to apply a separation between the femur and the tibia, and a varus/valgus indicator to indicate an angular alignment of the knee based on the intramedullary rod and the soft-tissue tensioning element.
