Patent number: 8888857Abstract: A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.Type: GrantFiled: September 5, 2012Date of Patent: November 18, 2014Assignee: Zimmer, Inc.Inventors: John E. Meyers, George D. Letson, Russell Windsor, Vincent A. Webster, Bill N. Sisk, Bill H. Haywood, Adam M. Griner, Michael Cook, Rodney L. Bays, Jerry L. Aikins, Marvin Figueroa, Peter S. Walker

Patent number: 8372083Abstract: An adapter to provide moveable configurations of securing structures such as fastener apertures or throughbores for fastening a surgical instrument to an anatomical structure, such as a bone. The adapter is connectable to the surgical instrument in a plurality of discrete locations on the surgical instrument, thereby allowing a surgeon to select an optimum fixation location for fastening the surgical instrument to the anatomical structure. The adapter may be cannulated to accommodate a fastener and may be slidably affixed to the surgical instrument while simultaneously providing stable fixation between the surgical instrument and the bone. The adapter may be configured to mate with another adapter having a similar configuration such that multiple fixation locations may be provided to the surgeon. Moreover, a plurality of adapters may be connected to the surgical instrument either directly or indirectly through another adapter to select multiple optimum fixation locations.Type: GrantFiled: December 21, 2006Date of Patent: February 12, 2013Assignee: Zimmer, Inc.Inventors: Jody L. Claypool, Robert A. Hodorek, Adam M. Griner

Patent number: 7935120Abstract: A method of preparing the proximal tibial and distal ends of the femur for the implantation of prosthetic components, including the steps of exposing the joint; resecting the distal end of the femur; resecting the tibia; and making a preliminary rough cut of a posterior portion of the pair of condyles. The rough cut is made by positioning a guide on the distal end of the femur and severing a small piece of the posterior portion of the pair of condyles. The rough cut is made prior to the step of resecting the tibia. The method may include finishing the femur by severing and removing a final piece of the posterior portion of the pair of condyles. The small piece removed in the preliminary rough cut step is sized to preserve enough of posterior portion to permit the removal of the final piece.Type: GrantFiled: April 29, 2005Date of Patent: May 3, 2011Assignee: Zimmer Technology, Inc.Inventors: Adam M.
