The use of cemented and cementless femoral components in revision total hip arthroplasty: a review of the literature

The choice of fixation in revising failed femoral components remain controversial. The early to mid-term re-revision rates for aseptic loosening of the revised femoral components ranged from 2% to 14% with early cementing techniques. They dreopped to 0% to 7% with improved cementing techniques, but the re-revision rates increased with time, and the rates of radiological loosening were still high. Early to mid-term re-revision rates ranged from 0% to 16% with proximally porous-coated femoral components, which also carried a significant intraoperative fracture risk that ranged from 12% to 46%. The most reliable option in femoral revision is probably the extensively porouscoated femoral component, the re-revision rates for which ranged from 0 to 6% after an average follow-up of 4 to 13 years.
