Treatment of Mycobacterium fortuitum Infection of Total Knee Arthroplasty: A Case Report

Mycobacterium fortuitum is a rapidly growing bacterium that can cause infection at different sites in humans. Prosthetic infection caused by this bacterium has historically been a challenge, with reimplantation being unsuccessful in all but one case. M. fortuitum is resistant to almost all conventional antituberculous medications. There is no standardised treatment due to its rarity of occurrence. Here, we report a case of successful reimplantation with initial debridement surgery and 6 weeks of antibiotics.

中文摘要偶然分枝桿菌是迅速生長的生物體，能於人體的不同部位造成感染。該細菌造成的假體感染一直是醫學史上的難題。迄今，感染後的重種手術只有一個成功的個案。幾乎所有常規抗肺結核藥物對該細菌都沒有效用。由於病例罕見，現時還沒有標準的治療方案。本文報告一個病例，最初以清創手術再加上六週的抗生素治療，成功地進行了人工全膝關節的重種手術。
