1. An implant comprising:
a collar having a proximate end, a distal end opposite the proximate end, an inner through bore extending therebetween, an exterior surface extending between the proximate and distal ends, a distal surface located adjacent the distal end for directly contacting a resected bone located adjacent an implant receiving area in a patient, and at least one recess configured to receive extravasating fixation medium, and external threads,
an elongated stem having a distal tip and a proximate end opposite the distal tip, and a collar-engagement feature having internal threads,
wherein the collar is configured to attach to the elongated stem, and the external threads of the collar are rotatably engageable with the internal threads of the collar-engagement feature, and
wherein the at least one recess extends from the distal surface into the collar and is located between the inner through bore and the exterior surface so as to be separated from the exterior surface, the at least one recess including a plurality of recesses, and wherein the collar is configured with one or more areas of internal space connecting two or more of the plurality of recesses, whereby the volume of fixation medium that can be taken in by the implant is maximized.
