Abstract
We report on 61 consecutive cemented acetabular revisions in which block allografts were used to reconstruct large defects. After a mean follow-up of 6.5 years, we observed satisfactory results when grafts had been rigidly fixed. Additional buttress-plates can improve the outcome. Paprosky type 3B defects had a double risk of failure. Cup migration had a 56% predictive value for failure. Several metal-backed cups failed, although the graft remained intact. There was a good improvement in functional outcome, which did not deteriorate up to a maximum follow-up of 11 years. Cemented revision total hip arthroplasty with the use of block allografts can give acceptable results in the medium to long term.
