What is septic arthritis?
Septic, or infectious, arthritis is infection of one or more joints by microorganisms. Normally, the joint is lubricated with a small amount of fluid that is referred to as synovial fluid or joint fluid. The normal joint fluid is sterile and, if removed and cultured in the laboratory, no microbes will be detected. With septic arthritis, microbes are identifiable in an affected joint fluid.
Most commonly, septic arthritis affects a single joint, but occasionally more joints are involved. The joints affected vary somewhat depending on the microbe causing the infection and the predisposing risk factors of the person affected. Septic arthritis is also called infectious arthritis.
