假体周围感染（PJI）仍然是全关节置换术后最常见的并发症之一。管理具有挑战性，与显著的发病率和死亡率相关，是医疗系统的财政负担。慢性PJI的2阶段管理失败并不少见。重复感染通常是多微生物的，多重耐药微生物，或新的生物。优化索引2阶段修订的成功是防止任何后续管理选项失败的最大方法，需要一个强大的基于团队的方法。
Periprosthetic joint infection (PJI) remains one of the most common complications after total joint arthroplasty. It is challenging to manage, associated with significant morbidity and mortality, and is a financial burden on the health care system. Failure of 2-stage management for chronic PJI is not uncommon. Repeat infections are oftentimes polymicrobial, multiple drug-resistant microorganisms, or new organisms. Optimizing the success of index 2-stage revision is the greatest prevention against failure of any subsequent management options and requires a robust team-based approach.
