Alumina-on-Alumina in THA [PDF]
Clinical Orthopaedics & Related Research, 2008 Different bearing surfaces, including alumina-on-alumina, have been used to avoid osteolysis. We prospectively followed 288 patients (319 hips) in which an alumina-on-alumina cup was used with a hydroxyapatite stem. The patients' mean age was 52.7 (range, 14-70 years), and the minimum followup was 3 years (mean, 4.7 years; range, 3-8 years).
