A prosthetic joint includes: (a) a bone-implantable first member comprising a rigid material and including a body having an annular flange extending outward at a first end thereof, the first end of the body and the flange cooperatively defining a wear-resistant concave first contact surface having a protruding rim and a recessed central portion； and (b) a bone-implantable second member comprising a rigid material with a wear-resistant convex second contact surface； (c) where the first and second contact surfaces bear directly against each other so as to transfer axial and lateral loads from one of the members to the other, while allowing pivoting motion between the two members； (d) wherein the flange is shaped so as to deform elastically and permit the first contact surface to conform to the second contact surface when the joint is placed under a predetermined load.
