Suppurative arthritis: Infectious arthritis. Suppurative arthritis is typically caused by a bacterial infection in the joint. Diagnosis is made by analysis of fluid that has been removed from the joint, including microscopic examination and culture. Suppurative arthritis requires drainage of the joint and antibiotics, usually intravenously administered.
Suppurative arthritis is also referred to as pyarthrosis, and bacterial or septic arthritis.
