Distal migration of the femoral component of a total hip replacement by as little as 0.33 mm during the first 6 postoperative months is predictive of the need for revision many years later. Because the fate of the prostheses is defined so early, it is unlikely that wear particles initiate loosening. However, the progression from the stage of early migration to clinical loosening has unknown causes, of which particles may be one. Slight instability associated with migration will lead to locally… CONTINUE READING
