{Reference Type}: Case Reports {Title}: Delayed Diagnosis of Mycobacteriumbovisbacillus Calmette-Guérin Periprosthetic Joint Infection Following Total Knee Arthroplasty. {Author}: Pelt CE;Shakir S;Cahill MJ;Pupaibool J;Cahill BC; {Journal}: Arthroplast Today {Volume}: 27 {Issue}: 0 {Year}: 2024 Jun 暂无{DOI}: 10.1016/j.artd.2024.101350 {Abstract}: Periprosthetic joint infection (PJI) can present challenges in diagnosis and treatment, particularly in the setting of atypical causative organisms such as fungi and mycobacteria. Herein, we present a case and provide a review of the diagnosis and treatment of an unusual PJI caused by bacillus Calmette-Guérin, administered during the treatment of bladder cancer 3 years prior to total knee arthroplasty and subsequent PJI. Although the patient's history of bladder cancer was known, neither his Bacillus Calmette-Guérin treatment nor its potential for distant site spread that could lead to PJI were appreciated, leading to a prolonged diagnostic evaluation and treatment course.
