Patent number: 11969353Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.Type: GrantFiled: June 3, 2020Date of Patent: April 30, 2024Assignee: Zimmer, Inc.Inventors: Steven Humphrey, James D. Wernle, Joanna Surma, Stephen H. Hoag, Donald W. Dye, Kenton A. Walz, Terry W. Wagner, Kathleen Macke, Duane Gillard, Brian D. Byrd, Ken Yamaguchi

Patent number: 9918844Abstract: A tibial prosthesis has a bearing component configured for an anterior-medial insertion, which advantageously avoids the extensor mechanism of the knee. A tibial tray may include a banana-shaped boss that corresponds to a notch formed in the bearing component. After the bearing component is inserted along the anterior-medial path, the boss is received within the notch by rotating the bearing component with respect to the tibial tray. This rotation seat the bearing component upon the tibial tray in the manner of a fixed-bearing prosthesis. Alternatively, the boss and notch may define angled central axes which allow straight anterior-medial insertion of the bearing component and locking engagement to the tibial tray.Type: GrantFiled: January 21, 2016Date of Patent: March 20, 2018Assignee: Zimmer, Inc.Inventors: Adam H.

Patent number: 9763794Abstract: A tibial prosthesis can include a bearing component and a tibial tray. The bearing component can include at least one concave articulating surface, a distal surface opposite said concave articulating surface, and a notch formed in said distal surface. The notch can define a longitudinal axis, the longitudinal axis defining an offset axis angle relative to the sagittal plane. The offset axis angle can range from greater than zero degrees to about 90 degrees. The tibial tray can include a support surface capable of supporting said bearing component, the support surface having a lateral edge and a medial edge opposite said lateral edge. The tibial tray can further include a boss having a longitudinal axis, the longitudinal axis angled with respect to the sagittal plane. The boss can be lockingly engageable with said notch along said offset axis angle to lock said tibial tray to said bearing component.Type: GrantFiled: October 25, 2013Date of Patent: September 19, 2017Assignee: Zimmer, Inc.Inventors: Adam H.
