1. A method of implanting a permanent talar implant assembly, comprising:
providing an articulation component having an articulating surface extending upwardly from a first plane to an apex and then downwardly toward the first plane, and configured to articulate with a tibial prosthetic device;
providing a base member, the base member including a cylindrical bore;
providing a distal portion, the distal portion including a stem configured to attach directly with a bone, and further including a spherical head;
coupling the provided articulation component, with the provided base member, at least one of the provided articulation component and the provided base member having a planar portion defining the first plane;
selecting an angular position for a longitudinal axis of the stem with respect to the first plane from a range of angular positions within a second plane perpendicular to the first plane, wherein the spherical head and the cylindrical bore are configured to allow the spherical head to be positioned in the cylindrical bore at any of a plurality of relative orientations, of the spherical head and the cylindrical bore, which define the range of angular positions and the provided distal portion and the provided base member are couplable at each of a plurality of angular positions within the range of angular positions;
orienting the stem with respect to the provided base member at the selected angular position with the spherical head at a first position at least partially within the cylindrical bore but not frictionally coupled with the cylindrical bore;
forcing at least one of the stem and the spherical head toward the other of the stem and the spherical head after the spherical head is at the first position thereby rigidly frictionally coupling the spherical head with the cylindrical bore with a rigid friction coupling sufficient for permanent implantation of the permanent talar implant assembly; and
implanting the stem in a bone of a foot.
