To review the diagnosis and treatment of prosthetic joint infection (PJI) with a focus on two-stage revision arthroplasty. The text will discuss different spacer constructs in total knee and total hip arthroplasty and will present clinical outcome data for these various options.
There is no appreciable difference in infection eradication between mobile and static antibiotic spacers. Mobile spacers have shown improved knee range of motion after second-stage re-implantation. Two-stage revision arthroplasty is the gold standard treatment for PJI. The first stage involves removal of all components, cement, and compromised soft tissues with placement of an antibiotic-impregnated spacer. Spacer options include both mobile and static spacers. Mobile spacers offer maintenance of ambulation and joint range of motion between staged procedures and have shown to be as effective in eradicating infection as static spacers.
回顾人工关节感染(PJI)的诊断和治疗,重点关注两阶段翻修关节成形术。本文将讨论全膝关节和全髋关节置换术中不同的间隔物构建,并展示这些不同选择的临床结果数据。
可移动抗生素间隔物和静态抗生素间隔物在根除感染方面没有明显差异。可移动间隔物在二期再植入后显示膝关节活动范围有所改善。两阶段翻修关节成形术是PJI的金标准治疗方法。第一阶段包括移除所有组件、骨水泥和受损的软组织,并植入抗生素浸渍间隔物。间隔物选项包括可移动间隔物和静态间隔物。可移动间隔物在分期手术之间可维持行走和关节活动范围,并且在根除感染方面已证明与静态间隔物一样有效。
