Tibial Tray with a Tibial Tray Shaft Structure and an Artificial Knee Joint

Abstract

A tibial tray with a distal surface, wherein a tibial tray shaft structure extends away from the distal surface in the distal direction. The tibial tray structure includes at least three shaft wall elements which are so arranged relative to each other that the cross-sections of the at least three shaft wall elements in a plane perpendicular to the distal direction are at least sections T-shaped, Y-shaped or X-shaped and the area of the cross-sections decreases strictly monotonously from the distal surface in the distal direction.
