Modular dual mobility (MDM) acetabular components are often used with the aim of reducing the risk of dislocation in revision total hip arthroplasty (THA). There is, however, little information in the literature about its use in this context. The aim of this study, therefore, was to evaluate the outcomes in a cohort of patients in whom MDM components were used at revision THA, with a mean follow-up of more than five years.

中期随访时，在翻修全髋关节置换术中模块化双活动髋臼组件是否存在问题？

模块化双活动性 (MDM) 髋臼假体通常用于降低翻修全髋关节置换术 (THA) 中脱位的风险。然而，文献中关于它在这种情况下的使用的信息很少。因此，本研究的目的是评估在翻修 THA 时使用 MDM 组件的一组患者的结果，平均随访时间超过 5 年。
