Abstract
Hydroxyapatite (HA) is commonly used on femoral stems to assist in osseous integration but there is limited evidence of the benefit it provides. We report a prospective comparison of 117 and 102 patients receiving either porous or HA coated sleeves respectively. Patients were evaluated at mean of 12.5 years in the porous and 13.7 years in the HA groups. The mean Harris Hip Score was 94.7 and 94.5 in the porous and HA groups respectively. One porous and 2 HA stems required revision. This study demonstrates that there is no long-term advantage to using an HA coating on the sleeve of this modular stem and confirms excellent long-term results for the SROM stem in a primary arthroplasty setting.
