PURPOSE: The purpose of this study was to assess survival rate, functional and radiological outcomes when using a hydroxyapatite-ceramic fully coated primary femoral stem in revision total hip arthroplasty. METHODS: Patients who underwent revision total hip arthroplasty using the Furlong hydroxyapatite-ceramic (HAC)-coated (Joint Replacement Instrumentation Ltd., Sheffield, UK) primary stem were retrospectively identified between 2013 and 2017. A total of 30 hips in 27 patients were identified and the mean follow-up duration was 44 months. Post-operative radiographs were scrutinized for signs of component loosening by two independent assessors. Patient's functional outcomes were assessed using the Oxford hip score and compared pre- and post-operatively. The prevalence of thigh pain was assessed at the latest follow-up. RESULTS: The most common cause of revision was adverse reactions to metal debris (ARMD) (46.6%). The overall complication rate was 13.3%. Results at final follow-up demonstrated 100% survival rate and no reported incidence of thigh pain. Using paired t test, all patients had a statistically significant (P < 0.05) improvement in post-operative mean Oxford hip score of 35 compared to a mean pre-operative score of 14. Radiographic analysis of the latest follow-up radiographs revealed no signs of component loosening or component subsidence. CONCLUSION: With a 100% survival rate and excellent reported functional outcomes, we believe that our experience and results support the use of primary cementless stems in selected revision cases.
