title: Femoral component revision with use of impaction bone-grafting and a cemented polished stem: a concise follow-up, at fifteen to twenty years, of a previous report.
abstract: We previously reported our results for thirty-three consecutive femoral component revisions with impaction bone-grafting, performed with the X-change femoral revision system and a cemented polished Exeter stem, at a minimum of eight years of follow-up. The present updated study shows the results after fifteen to twenty years. One stem was revised again for mechanical reasons during a rerevision of an acetabular cup. The probability of survival at seventeen years was 96% (95% confidence interval [CI], 72% to 99%) with a femoral rerevision for any reason as the end point and 100% (95% one-sided CI, 69% to 100%) with rerevision for aseptic loosening as the end point. The average subsidence was 3 mm and stable relative to our previous report. Although three early femoral fractures occurred after this surgery, in this update no additional fractures were seen. In conclusion, the probability of survival of femoral component revisions with impaction bone-grafting and a cemented polished stem was excellent at a mean of seventeen years.
