title: Revision total hip replacement using the bias proximal porous-coated femoral component.
abstract: Revision total hip replacement (THR) to replace the loose femoral component using BIAS proximally porous-coated femoral revision stem was followed up in 39 patients for five years. In six cases a new revision of the stem was carried out for symptomatic stem loosening and five more were definitely loose and in 15 cases radiographs revealed clear radiolucent periprosthetic zones evidencing fibrous integration. The survival of the BIAS revision stem was 83% after five years. The mean Harris hip score (HHS) was 75 points and the final result was excellent in six, good in eight, fair in four and poor in 16 cases. The outcome was unacceptably poor and the use of this stem should be abandoned in THR revisions.
