Abstract

Perfections introduced in the knee joints for prosthesis of a femur, the upper part of which carries at one end of the body of the femur and disposed on both sides of a central plane approximately elliptical profile running surfaces copied approximately from the natural support surfaces of the natural femur, whose elliptical surfaces develop on opposing surfaces, corresponding to an approximately cylindrical profile of a lower part, the lower part simultaneously exerting with respect to the upper part a relative movement with a horizontal component, characterized in that the upper part and the the lower part of the articulation are articulated to each other through a single ambulatory guide axis, there being at least one partition provided with an oblong hole that allows a traveling displacement of the guide axis at least in a perpendicular direction and in which it is driven the axis of g he was mounted on the other side when the knee flexed.
