Abstract:
A 25-year-old female presented with left knee pain following arthroscopic synovectomy for presumed pigmented villonodular synovitis (PVNS). Radiographs and magnetic resonance imaging demonstrated tricompartmental arthritic changes. She underwent a two-stage procedure first involving antibiotic spacer implantation, followed 1 week later by spacer removal and definitive total knee arthroplasty (TKA) once initial intraoperative culture results were negative. Subsequent cultures confirmed tuberculosis septic arthritis. Repeat evaluation 1 year postoperatively showed no complications and patient satisfaction with left knee function. This is a unique case report in the United States describing 1-year outcomes following staged TKA for tuberculosis septic arthritis masquerading as PVNS.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
