With an increase of revision total hip arthroplasty (THA), the choice of bearing surface becomes more important. Wear debris by conventional metal-on-polyethylene articulations may cause extensive osteolysis, especially in young patients. We analyzed the clinical and radiographic outcomes after revision THA using third-generation ceramic-on-ceramic bearing surfaces in 42 hips. The mean age of the patients was 48.8 years (32-59 years), and the mean duration of follow-up monitoring was 5.4 years (3.2-8.0 years). At final follow-up examination, the average Harris Hip Score was 91.3. Although minor complications were observed in 6 hips (14.3%), no hips required additional revision surgery. No hip showed radiolucent lines, acetabular cup migration, or osteolysis. Our data show that clinical and radiographic outcomes after revision THA using third-generation ceramic-on-ceramic bearing surfaces are favorable. Ceramic-on-ceramic bearing surfaces can be preferentially considered for revision THA, especially in young patients. Further studies with long-term follow-up data are warranted.
随着翻修全髋关节置换术(THA)的增加,选择轴承表面变得更加重要。传统的金属对聚乙烯关节的磨损颗粒可能会导致广泛的骨溶解,尤其是在年轻患者中。我们分析了 42 髋使用第三代陶瓷对陶瓷轴承表面进行翻修 THA 的临床和影像学结果。患者的平均年龄为 48.8 岁(32-59 岁),平均随访监测时间为 5.4 年(3.2-8.0 年)。在最终随访检查时,平均 Harris 髋关节评分为 91.3。虽然有 6 髋(14.3%)观察到轻微并发症,但无髋需要进一步翻修手术。没有髋显示透光线、髋臼杯迁移或骨溶解。我们的数据表明,使用第三代陶瓷对陶瓷轴承表面进行翻修 THA 的临床和影像学结果是良好的。陶瓷对陶瓷轴承表面可优先考虑用于翻修 THA,尤其是在年轻患者中。需要进一步进行长期随访数据的研究。
