Abstract
We report the mean 15.2 year follow-up results for a porous coated version of the Bi-Metric (Biomet UK Ltd, Bridgend, UK) uncemented femoral stem in young patients. Sixty-four hips were implanted into 54 patients (mean age, 54.3 years) and followed up using the Hospital for Special Surgery score and regular radiographs. The first 13 patients had a TTAP-ST acetabulum (Biomet UK), the remainder receiving a Universal cup (Biomet UK). At 15.2 years, there were no stem failures or femoral revisions. The mean Hospital for Special Surgery score was 34.7 (20-40), and there was no evidence of stem loosening radiologically. There were 3 acetabular revisions and 3 liner changes at 10 years, with a further 5 cup revisions and 9 liner changes at final follow-up.
