Revision of Hip Resurfacing Arthroplasty to Neck Sparing “ARC” Total Hip Arthroplasty

Modern hip resurfacing arthroplasty (HRA) with a metal-on-metal articulation has attracted many patients worldwide over the last 15 years for the potential benefits of high activity level and bone preservation.  Good mid-term results are reported, especially in male patients. However, there is now a need for revision options for a subset of patients who will require early revision for unanticipated adverse local tissue reaction (ALTR) associated with the metal-on-metal articulation.  We present a case of HRA conversion to total hip arthroplasty (THA) using a neck-sparing THA component.
