Publication number: 20230113335Abstract: According to one example, a tibial prosthesis that can include a tibial bearing component, tibial baseplate, an insert and a fastener. The tibial bearing component can have medial and lateral proximal articular surfaces and an opposing distal surface. The tibial bearing component can define at least one recess therein with the recess having an opening at a periphery of the tibial bearing component. The tibial baseplate can be coupled to the tibial bearing component on the proximal surface thereof and having a distal surface configured to be disposed on a resected proximal surface of a tibia. The insert can be configured to be disposed within the recess and can engage the tibial baseplate and the tibial bearing component. The fastener can be insertable into the tibial bearing component and can be configured to retain the insert to the tibial baseplate.Type: ApplicationFiled: December 14, 2022Publication date: April 13, 2023Inventors: Brian D. Byrd, Kathleen Macke, Dwight T. Todd, James D. Wernle, Vanessa Croll, Jeff Blaylock, Abraham P. Habegger

Publication number: 20220233321Abstract: According to one example, a femoral prosthesis system is provided that has a plurality of sizing options using two families of femoral prostheses is disclosed. The second family of femoral prostheses can have a predetermined increase in femoral posterior condylar offset relative to the first family of femoral prosthesis. In one example, the second family of femoral prostheses can have the predetermined increase in the femoral posterior condylar offset while maintaining substantially a same femoral medial-lateral condylar extent relative to a comparably sized one of the first family of femoral prostheses.Type: ApplicationFiled: April 11, 2022Publication date: July 28, 2022Inventor: Vanessa Croll

Patent number: 10835382Abstract: According to one example, a tibial replacement assembly for a knee arthroplasty can be configured to couple to a resected proximal surface of a tibia of a human knee. The tibial replacement assembly can include a tibial tray and a first spike. The tibial tray can include a proximal surface and a distal surface opposing the proximal surface. The distal surface can be configured to be disposed on a resected proximal surface of a tibia. The first spike can be removably secured to the tibial tray and can extend generally distally away from the distal surface. The first spike can be configured to extend beneath the resected proximal surface of the tibia.Type: GrantFiled: January 18, 2018Date of Patent: November 17, 2020Assignee: Zimmer, Inc.Inventors: Abraham P. Habegger, Steven Lyons, Wolfgang Klauser, Vanessa Croll, Michael John Collins

Patent number: 10271954Abstract: Methods, techniques and apparatuses are disclosed including exemplary methods of performing a knee arthroplasty of the tibia. One exemplary method can include determining at least a depth of a distal fixation feature of a tibial implant, and forming a metaphyseal recess in a proximal portion of the tibia. The recess can be configured to receive the distal fixation feature therein and can be sized to exceed at least the depth of the distal fixation feature such that when a distal surface of the tibial implant contacts a proximal surface of the proximal portion of the tibia and the distal fixation feature is received in the metaphyseal recess, a gap remains between the distal fixation feature and one or more surfaces that form a portion of the metaphyseal recess.Type: GrantFiled: January 18, 2017Date of Patent: April 30, 2019Assignee: Zimmer, Inc.Inventors: Brian Edward Roach, Fred A. Wentorf, Amanda Szalkowski, Vanessa Croll, Tyler Bell
