M00-M03: Infectious arthropathies

M00: Pyogenic arthritis

Pyogenic arthritis, also known as septic arthritis, is an inflammatory condition caused by a bacterial infection in a joint. This group of conditions can arise when bacteria travel through the bloodstream from another part of the body, such as the lungs during a bout of pneumonia, and set up in a joint. Other times, the joint can become infected due to injury or surgery. Regardless of the source, the bacteria can cause significant inflammation and damage in the joint, leading to symptoms such as severe pain, swelling, and fever. These symptoms often develop very rapidly. Without swift treatment, the cartilage and bone within the joint can become deeply damaged, potentially leading to lasting disability. The condition can affect any joint, but it most commonly targets the knees.
