Abstract:
1. A joint prosthesis, in particular a knee joint prosthesis for establishing an articulated connection between a first bone and at least one second bone of a patient, said prosthesis comprising a first component, which is at least indirectly connectable to the first bone, at least one second component, on which the second bone is at least indirectly supportable and which is movably mountable on at least one bearing surface of the first component, a connection element connecting the first component to the second component, said connection element comprising at least one elastically deformable element consisting of a multiple-bend leaf spring enabling an excursion of the first component relative to the second component from an initial position, wherein upon the excursion of the first component the elastically deformable element generates a restoring force acting upon the first component to restore the first component to the initial position thereof; the connection element further comprising a connection pin engaging into a bore which is provided in the first component to thereby form a bearing between the first component and the second component, and wherein the connection pin is connected to said multiple-bend leaf spring in a middle portion of the leaf spring.
