• at least one bone engaging feature disposed on the outer surface of the insertion extension portion adjacent to the distal end of the insertion extension portion, wherein the at least one bone engaging feature is at least one of a protrusion and a cavity, wherein the at least one bone engaging feature comprises a plurality of bone engaging features disposed in an array about the distal end of the insertion extension portion, and the array of bone engaging features comprises two or more rows of bone engaging protrusions;
• and
• a porous coating disposed on the outer surface of the insertion extension portion adjacent to the proximal base;
• and
• engaging the at least one engaging feature with the resection to securely lodge the bone cap within the resection.
