The complexity of bone movement in the knee articulation requires a
study of its anatomy to achieve a knee prosthesis device.
A good prosthesis
presents surface shapes allowing all physiological movements of the knee.
Thus it must present a shape as close as possible to the physiological mean
surfaces of the knee articulation.
The new type of prosthesis presented here, is the result of such a scientific
We measure the human bone surfaces of a significant population with a
triaxial measuring machine and we compute a middle surface used as a basic
surface for our study.
Then, using B-splines technics, we study the parameters allowing to build
again the condyle surface respecting ligament kinematics and constraint
