  • Publication number: 20060206210
    Abstract: An artificial joint for a patient includes a joint plateau having a recess including a first dimension and a joint overlay having a projection corresponding to the recess and a second dimension, the second dimension being larger than the first dimension at a body temperature of the patient. The projection is insertable into the recess by virtue of a temperature difference of at least one of the projection and the recess with respect to the body temperature. A contact area is formed between the projection and the recess at the body temperature. At least one of the second dimension and the contact area is determined such that fixation forces exerted on the projection at the body temperature create a state of stress in at least one of the joint overlay and the joint plateau, the state of stress improving at least one of a load-bearing capacity and a durability of the artificial joint.

  • Patent number: 6902582
    Abstract: An artificial joint (1) suitable for use as an endoprosthesis for a human knee joint, having a first joint compartment (2) formed by a first condyle (3) and a first socket (4) and a second joint compartment (5) formed by a second condyle (6) and a second socket (7). The contact surfaces (C) of the respective joint compartments (2, 5) are offset in the main functional plane. To further improve the characteristics of the artificial joint (1), the contact surfaces (C) of the two joint compartments (2, 5) are sloped as a function of the flexion angle such that the surface normals (8, 9) of the contact surfaces (C) have a common point of intersection at every flexion angle. This arrangement of the contact surfaces (C) achieves self-stabilization of the joint (1) both when a rotary motion or torsion and when lateral forces are introduced.

  • Patent number: 6443994
    Abstract: An exoprosthesis/orthosis for the human knee-joint comprised of an upper leg part (1) which can be connected to the human upper leg, and a lower leg part (2) which can be connected to the human lower leg. Both leg parts (1, 2) are connected at least via a joint which constructs a joint with two joint axes (MU, M0), i.e. a so-called dimeric joint chain, which are connected such that they carry out a forced movement. A polode (movement or rest polode) is assigned to each respective leg part (1, 2) with regard to the momentary joint axis of said leg parts, whereby curved teeth (5, 7) are constructed on the upper leg part (1) and on the lower leg part (2). The teeth interact similar to sprocket gearing in the movement functional area of the joint (3), whereby the curved teeth coincide with the polodes (t, f) of both leg parts (1, 2) in the movement functional area.

  • Patent number: 6312471
    Abstract: An artificial condyle (2) for use in a human hip joint in which the condyle has a spherical joint shell (1) which has a radius of curvature R1 and a curvature midpoint M1 and in cross-section a circular concave section contour. A functional surface which is convex at least in a region which articulates in the joint shell (1) is designed as a sphere such that when it is inserted in the shell (2), in a longitudinal plane X—X passing through the midpoint M1, a radius RK1=R1 is formed which has a midpoint MK1 coinciding with M1. A transverse plane Y—Y perpendicular to the longitudinal plane X—X has, passing through the midpoint MK1, a radius RK2<RK1 having the midpoint MK2. In the transverse plane Y—Y a stable dimeric joint chain is formed, with which the joint axis path of the midpoints MK1 and MK2 has a joint path radius R=RK1−RK2.
