Patent number: 8137407Abstract: A mobile bearing knee prosthesis apparatus includes a tibial plate. The tibial plate includes a medial lobe and a lateral lobe conjoined in a dividing plane. The apparatus further includes a tibio-femoral insert and a stud-like protuberance extending from the tibial plate into the tibio-femoral insert. The stud-like protuberance includes a protuberance sidewall positioned in the tibio-femoral insert. The protuberance sidewall is bisected by the dividing plane and includes a pair of opposing eccentric convex arcuate portions, and the tibio-femoral insert is moveable relative to the tibial plate about an axis medially disposed from the dividing plane. A mobile bearing knee prosthesis apparatus includes a tibial plate and a tibio-femoral insert coupled to the tibial plate. The tibio-femoral insert includes a generally posteriorly positioned chamfered superior surface and defines a generally posteriorly positioned generally U-shaped space bounded at least in part by the chamfered surface.Type: GrantFiled: March 9, 2005Date of Patent: March 20, 2012Assignee: Zimmer, Inc.Inventors: Dwight T. Todd, Brian D. Byrd, James C. Harris, Kim C. Bertin, Linggawati Tanamal, Peter S. Walker

Patent number: 7018381Abstract: An apparatus for removing an osteophyte includes an elongated member. A portion of the elongated member includes a blunt end. A burr extends from this portion at a location proximal to the blunt end. An alternative embodiment includes a generally tongue-shaped elongated member. The elongated member includes a first portion and a second portion that define a passageway. The second portion includes a blunt end. At least one of a post and a wall extend from the first portion. A burr is coupled the second portion and the passageway at a location proximal to the blunt end. The burr includes a base with a generally pie-slice shaped perimeter, and includes a generally convex surface extending from the base. The generally convex surface includes a smooth portion facing generally toward the blunt end and a perforated, non-smooth portion facing generally toward the first portion of the elongated member.Type: GrantFiled: October 18, 2002Date of Patent: March 28, 2006Assignee: Zimmer Technology, Inc.Inventors: Jeff Michael, Rodney Bays, Jamie Hanneken, Michael Daniels, Robert Hodorek, Scott Steffensmeier, Lynn Kirkpatrick, Linggawati Tanamal

Publication number: 20050187560Abstract: An apparatus for sizing a distal femur includes a base configured to concurrently abut a distal surface and a posterior surface of the distal femur, and further includes an axial distance scale. The scale includes a first sleeve axially fixedly coupled to the base and further includes a second sleeve spirally movably coupled to the first sleeve. A method for sizing a distal femur includes concurrently abutting a base against a distal surface and a posterior surface of the distal femur, and further includes measuring a distance relative to the base. The measuring step includes spirally moving a first sleeve relative to a second sleeve.Type: ApplicationFiled: January 28, 2005Publication date: August 25, 2005Inventors: Steven Dietzel, Toby Farling, Adam Griner, Robert Hodorek, W. Kuester, Vincent Webster, Alyssa Perry, Linggawati Tanamal

Publication number: 20050149091Abstract: An osteotome including a head portion is provided. The head portion includes a first substantially planar surface and a second substantially planar surface extending obtusely from the first substantially planar surface. The osteotome further includes a bone cutter extending from the first substantially planar surface, and an elongated portion extending from the head portion. The first substantially planar surface and the second substantially planar surface face away from the elongated portion.Type: ApplicationFiled: January 3, 2004Publication date: July 7, 2005Inventors: Linggawati Tanamal, James Harris, Kim Bertin, William Kennedy

Patent number: 6319283Abstract: An orthopaedic knee component for implanting within a proximal tibia includes a tibial tray with a proximal tibial plateau and a projection extending generally orthogonal to the tibial plateau. The tibial tray also includes a distally extending stem. A bearing is coupled with the tibial plateau and has an articular bearing surface for engagement with a femoral component. The bearing is rotationally movable between a first rotational limit and a second rotational limit about an axis extending generally orthogonal to the tibial plateau. The bearing has a backing surface engaging the tibial plateau which is sized and shaped such that the backing surface is substantially entirely supported by the tibial plateau at any position during rotational movement between the first rotation limit and the second rotational limit.Type: GrantFiled: July 2, 1999Date of Patent: November 20, 2001Assignee: Bristol-Myers Squibb CompanyInventors: John Insall, Audrey Patmore, Christopher McLean, Linggawati Tanamal, Clayton R.
