Abstract
A prosthetic bone joint device, developed initially for the knee but applicable to other joints, has first and second components each with a laterally-spaced pair of respectively convex and concave bearing surfaces, and each with a seating surface bridging the respective bearing surfaces, the seating surface being of V-shaped profile longitudinally of the component. The components are disposed with their bearing surfaces in mutual articulatory engagement, and with the V-apices of their seating surfaces in closely-spaced parallel relation, and have at least two elongate flexible linkage members extending with their opposite ends connected to respectively different ones of the components in a crossed configuration seated on the seating surfaces.
