1. An orthopaedic implant for shoulder arthroplasty comprising:
an implant body extending along a central axis between a front face and a rear face, the rear face dimensioned to abut bone, and an anchor member extending outwardly from the rear face, the anchor member dimensioned to secure the implant body to bone;
wherein the front face includes a concave articular surface dimensioned to mate with an opposed convex articular surface of an implant or bone, the articular surface including a first non-spherical contour extending across a length of the front face between first and second lips that establish a perimeter of the implant body, and the first lip is outward of the second lip relative to the central axis;
wherein a trough of the first contour is established between the central axis and the second lip, and a radius of curvature of the first contour decreases from the trough towards the first lip; and
wherein a second non-spherical contour of the articular surface extends across a width of the front face at the trough, and a radius of curvature of the second contour decreases from the trough towards a perimeter of the articular surface.
