Septic arthritis is an orthopedic emergency that can lead to significant morbidity and mortality. Polyarticular involvement is a relatively rare phenomenon occurring primarily in high-risk patients.
In this article, we report the rare case of a patient with rheumatoid arthritis presenting with an acute episode of septic arthritis involving most of the joints of the body. Surprisingly, his bilateral total hip arthroplasties were completely unaffected.
Unusual polyarticular presentations of septic arthritis, though rare, must still be considered within the differential diagnosis by all healthcare providers when treating certain high-risk groups.
