Analysis of revision surgery of resurfacing hip arthroplasty.

Results of revision of 24 resurfacing hip prostheses followed up for a minimum of one year are encouraging. The average Iowa Hip Rating after salvage was higher than the average highest rating prior to failure of the original resurfacing procedure. There were no intraoperative complications in revising any of the failed resurfacing procedures. Results of revision of the failed component of a resurfacing procedure are comparable with those of conversion to a conventional hip arthroplasty. Thorough, prompt evaluation of hip pain in recipients of a hip resurfacing procedure is necessary for preservation of remaining bone stock. In comparison to revision of conventional hip arthroplasty, revision of failed resurfacing hip arthroplasty is technically easier and has a better prognosis in providing the patient with a pain-free, functional hip.
