M01: Direct infections of joint in infectious and parasitic diseases classified elsewhere
M01.0: Meningococcal arthritis
Meningococcal arthritis is a specific type of infectious arthritis caused by the bacteria Neisseria meningitidis, typically known for causing meningitis. This condition emerges when the bacteria directly infects the joint, often after a case of meningococcal meningitis or through bloodstream. It is characterized by sudden onset of severe pain, swelling, and tenderness in the infected joint, usually the knee. Fever and chills may also occur alongside these symptoms. Due to the infectious nature of the bacteria, this condition may rapidly progress and could potentially lead to irreversible joint damage if not treated timely. However, the impact on other systems of the body depends on each individual case and progression of the infection.
