In this retrospective study, we evaluated the aseptic loosening rate and initial result of an extensively hypoxyapatite-coated high offset (127°) titanium femoral component in 27 consecutive femoral revisions. Fourteen men and 12 women (mean age, 68 years) were followed for 2 to 7 years. Preoperative, 3 month, 6 month, and yearly follow-ups included Harris Hip Scores and radiographic analysis. Femoral stem length was 155-205 mm; distal stem diameter was 12-20 mm. Extended trochanteric osteotomies were necessary on 7 cases. At a mean 53 months follow-up, there were no loose femoral components (ie, bone ingrown in all cases) and no subsequent femoral stem revisions. Thus far, this high offset stem has demonstrated an excellence rate of stable bone fixation.
