Primary meningococcal oligoarthritis of the knee—case report and review of the literature

Abstract

This report is of a healthy 49-year-old male with an isolated primary single-joint septic arthritis of the right knee. The patient had no clinical symptoms or signs of systemic meningitis or detectable meningococci in the blood. The presentation is rare and can be unusual. Complete recovery does usually occur if appropriate antibiotics therapy, joint aspiration and repeat washouts are performed early.
