Septic Knee Arthritis Caused by Corynebacterium striatum / 대한정형외과학회잡지

ABSTRACT

Corynebacterium striatum (C. striatum ) is an aerobic Gram-positive rod, which is an organism of the respiratory tract and skin. Because of its low virulence, it is usually thought to be a contaminant even if it is shown in culture tests, but it can cause endocarditis and respiratory infections, and rarely meningitis and arthritis. Infection with C. striatum has been reported in patients with reduced immunity, as well as in patients with catheter or broken skin barriers. Septic knee arthritis caused by C. striatum infection is rarely reported, and knee joint infection by C. striatum in patients who underwent arthroscopic debridement for previous septic arthritis is even more rare. Therefore, we report a case of septic knee arthritis caused by C. striatum that was improved by early diagnosis and arthroscopic treatment.
