Long-term results of revision total hip replacement. A follow-up report.

The results of 110 revision total hip replacements performed for aseptic failure, with an average follow-up of 3.4 years, were reported in 1982. We were able to continue to follow ninety-nine of these patients for an average of 8.1 years (range, five to 12.5 years). With this longer follow-up, we found that twenty-nine (29 per cent) of these revised arthroplasties have since failed. Most of the failures after 1982 occurred in the hips that were known to have a progressive radiolucency at the time of the first evaluation. We concluded that there is an increased failure rate with longer follow-up of revision total hip replacement, and that progressive radiolucency at an interface indicates a poor prognosis for the arthroplasty.
