Prosthetic surface replacement of the hip has been performed since the 1960's, with resurgence in interest in the 1990's and then diminishing popularity since the late 2000s.  Dr. Murphy personally prefers the use of superior hip approached with computer-assisted techniques.  These procedures are usually combined with ceramic-ceramic bearings in younger, active patients.  The clinical results of these procedures have exceeded any long term results of hip resurfacing which is why these minimally invasive hip arthroplasties are preferred.
