Isolated revision of the femoral component of hip resurfacings to metal-on-metal (MoM) total hip arthroplasties has shown inferior results. We present a case series of well-fixed, painful MoM hips with elevated chromium and cobalt levels. An isolated femoral revision using a noncemented femoral component and a double-mobility head was performed. Patients were followed up for 6 months and showed excellent improvements in visual analog score and Hip dysfunction and Osteoarthritis Outcome Score (HOOS). Cobalt and chromium levels dropped at 6 weeks and were normal at 6 months. Although our follow-up is short, we feel that it is important to highlight this as a potential treatment strategy. This revision is less aggressive than traditional methods, eliminates the concerns from MoM bearings, and results in a stable construct.
