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.

Tibial knee component with a mobile bearing

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.

Apparatus for removing an osteophyte

A femoral component for a prosthetic knee implant system. The femoral component comprises medial and lateral condyles, wherein the height of the medial condyle is greater than the height of the lateral condyle.

An implant sterilization tray includes an integral torquing fixture for holding an implant stationary. By incorporating the fixture into the instrument tray, a large, stable base is provided for holding the implant. The user can more readily hold the implant in a stable position with the implant resting in the case and the case resting on a table.

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.

The present invention provides a prosthetic implant 1 which includes a stem 2 having two lateral fins 20. The lateral fins 20 extend outwardly from the lateral side 6 of the stem 2, such that the lateral face 21 of each fin 20 is flush with the lateral side 6 of stem 2.
