Patent number: 11160659Abstract: According to one example, a tibial bearing component for articulation with a medial condyle and a lateral condyle of a femoral component in a knee replacement procedure is disclosed. The tibial bearing component can include a distal surface and an articular surface opposing the distal surface. The articular surface can include a medial compartment and a lateral compartment configured for articulation with the medial condyle and the lateral condyle of the femoral component, respectively. The lateral compartment can have a lateral articular track with a lateral anterior-posterior extent. The lateral articular track can comprise a plurality of distal-most points along a proximal surface of the lateral compartment that are contacted by the lateral condyle during rollback of the femoral component. The medial compartment can differ in configuration from the lateral compartment and can have an anterior lip height of between about 9 mm and about 13 mm.Type: GrantFiled: March 13, 2019Date of Patent: November 2, 2021Assignee: Zimmer, Inc.Inventors: Nick Drury, Jeff Blaylock, Stephen E. White, Calie B. Grey

Publication number: 20140222155Abstract: In typical knee repair or replacement surgery, a femoral implant includes a pair of convex condylar surfaces that can slide within corresponding concave bearing indentations on a tibial bearing surface. The tibial bearing surface is disposed on a proximal side of a tibial platform. A stem can extend distally from the tibial platform, and can attach to a cut proximal end of the tibia. A tibial augment can attach to the distal side of the tibial platform, and can reduce or eliminate a lateral overhang of the tibial platform with respect to the cut proximal end of the tibia. The tibial augment may have a tapered periphery. The taper may extend inward in a distal direction. The taper may vary along the periphery of the tibial augment, so that at least a portion of a medial taper is different from at least a portion of a lateral taper.Type: ApplicationFiled: February 5, 2014Publication date: August 7, 2014Inventors: Dianne S. Metzger, Ian R. Vaughan, Calie B. Grey
