The scientific problems for the creation of a knee prosthesis device

Author(s): J.C. Jlinger & G. Maurice Abstract: entific problems for the creation of a knee prosthesis device J.C. Jlinger & G. Maurice Laboratoire de Science et Genie des Surfaces, Ecole des Mines de Nancy, Pare de Saurupt, 54042, Nancy Cedex, France ABSTRACT 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 approach. 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 transmiss...
