a femoral stem; and
an inserter arranged and configured to couple to the femoral stem to facilitate insertion of the femoral stem within an intramedullary canal of a patient's bone, the inserter including a quick-connect, non-threaded connection for coupling the femoral stem;
wherein the femoral stem includes a cavity comprising a ramped pathway in communication with a pocket, the inserter includes an enlarged head portion comprising a ball-shaped head portion extending from a distal end of the inserter, the head portion being arranged and configured to be received within the cavity of the femoral stem to couple the inserter to the femoral stem while enabling an orientation of the inserter to be angularly adjustable relative to the femoral stem, the ramped pathway being arranged and configured to guide the ball-shaped head portion into the pocket.
