An orthopedic joint replacement (100,300,400) has first and second joint components that can be placed in load-bearing articulation with one another. The first joint component (10,330,410) has first and second convex spherical condylar segments defining first (14) and second radii (15). The second joint component (20,310,320,420) has a spherical first concave condylar segment (28) with a radius equal to the radius of the first convex spherical condylar segment. The second joint component also has a non-spherical second concave condylar segment (29). The first convex spherical condylar segment of the first joint component is in congruent contact with the first spherical concave condylar segment of the second joint component. The second spherical convex condylar segment of the first joint component is in line contact with the non-spherical concave condylar segment of the second joint component.
