We conducted a prospective study to evaluate the long-term results after Corin C-Fit uncemented total hip arthroplasty in young patients with hydroxyapatite or porous coated components.
We prospectively followed 36 patients (38 hips) who had Corin C-Fit uncemented total hip arthroplasties by eight experienced consultant surgeons at two centres. The acetabular and femoral components were hydroxyapatite or porous coated.
The overall 10-year survival rate for the Corin C-Fit arthroplasty was 43%. The 10-year survivorship for the femoral implant was 56% and for the acetabular component 59%.
The evidence presented in this study suggests that the Corin C-Fit uncemented total hip arthroplasty has one of the highest mid- and long-term failure rates for both femoral and acetabular components in the literature. We believe this implant should not be used and patients who have had this form of total hip arthroplasty should be kept under regular review.
我们进行了一项前瞻性研究，以评估在年轻患者中使用羟基磷灰石或多孔涂层组件的Corin C-Fit非骨水泥型全髋关节置换术后的长期结果。
我们前瞻性地随访了由两个中心的八位经验丰富的顾问外科医生进行Corin C-Fit非骨水泥型全髋关节置换术的36例患者（38髋）。髋臼和股骨组件为羟基磷灰石或多孔涂层。
Corin C-Fit关节置换术的总体10年生存率为43%。股骨植入物的10年生存率为56%，髋臼组件为59%。
本研究提供的证据表明，Corin C-Fit非骨水泥型全髋关节置换术在文献中是股骨和髋臼组件中长期失败率最高的之一。我们认为不应使用这种植入物，接受这种全髋关节置换术的患者应定期接受复查。
