Abstract
- Background: Due to the adverse effects of cemented hip arthroplasty, uncemented stems with hydroxyapatite (HA) coating reduces these risks and enhanced integration. The concept of an extensive HA coating for the fixation of a tapered femoral stem (Corail) was introduced, which can achieve durable biological fixation and preserve normal periprosthetic bone activity. Here we describe the clinical and radiological outcome in patients with the Corail stem. Methods: 92 total hip replacements in 81 patients using the Corail stem were followed-up. 47 patients were women, and the mean age at surgery was 62.9 ± 8.7 (34-71) years. The indications included: osteoarthritis of the hip (71.1%), avascular necrosis (13.6%), femur neck fractures in elderly (9.7%) and post-traumatic osteoarthritis (6.8%). Findings: Eight patients died during follow-up. The revision was only found in two patients due to line wear and resulted in an 10-year Kaplan-Meier estimated overall survival rate of 97.83%. The clinical results were good, with a mean Harris hip score of 92.3 ± 5.6 (72-100). The mean total Merle d'Aubigné and Postel score was 6.8 ± 0.5 pre-operatively and 16.1 ± 1.4 at latest follow-up. All unrevised implants were radiographically stable, with a mean liner wear of 0.07 mm/year. Conclusion: This long-term analysis confirmed the durability of the functional and radiographic results. Our findings suggest the long-term results of Corail HA-coated stem are more satisfactory which is preferable to any other system. [ABSTRACT FROM AUTHOR]
