Abstract:
1. A knee joint prosthesis with a first body associated with the thigh and a second body associated with the lower leg, which engages around the first body in fork fashion, whereby arched guiding elements with a variable curvature are provided in the first body, into which engage bolts of the like of the second body wherein in each of the limbs of the fork-shaped first body two guiding elements with a variable curvature are provided, whereby in each case a bolt or the like of the second body engages into each of the guiding elements, and the points X P (φ), Y p (φ) of the first guiding element and the points X Q (φ), Y Q (φ) of the other guiding element correspond approximately to the following equations: whereby the deflection angle of the knee joint is indicated in radians, the points X P (φ), Y P (φ) of the first guiding element and the points X Q (φ), Y Q (φ) of the other guiding element corresponding approximately to the following equations: where the deflection angle φ of the knee joint is indicated in radians.
