A total ankle prosthesis that includes a talar component that has a bone contacting side for contacting a talus and an articular side opposite the bone contacting side. The articular side has first and second condyles separated by an intercondylar notch. The first condyle defines a spheroidal convex surface. The prosthesis also includes a tibial component that has a bone contacting side for contacting a tibia and an articular side. The articular side has first and second condyles separated by an intercondylar spine. The first condyle of the tibial component defines a concave surface. The concave surface has a condylar edge that defines a perimeter thereof and a plurality of articular portions positioned between anterior and posterior extents of the condylar edge. A first articular portion of the articular portions is spheroidal and a second articular portion is defined by a cylindrical helix.
