Abstract
Impaction bone grafting with a cemented polished double-taper stem as a technique for revision of the femoral component was introduced in 1987 at our institution.
As at January 2000, 540 cases in 487 patients had been performed. All procedures have been studied prospectively and there are no patients lost to follow-up. We present the survivorship and outcome data for these patients.
Survivorship at 15 years is 90.6 percent [95 percent confidence interval: 88–93 percent]. Clinical scores show marked and sustained improvement.
There have been 45 failures [8.3 percent]. Technical error contributed to 13 of the 24 non-infective complications, but with improved technique plus the addition of long stemmed impaction grafting, there have been no technical errors since 1996.
Our results show that revision of the femoral component with impaction bone grafting is a reliable and durable technique with an acceptably low complication rate and with excellent survivorship at 15 years.
