What is septic arthritis?

Septic arthritis is an infection in the joint (synovial) fluid and joint tissues. The infection usually reaches the joints though the bloodstream, although some joints may become infected due to an injection, surgery, or injury. Different bacteria and viruses can infect a joint and usually are associated with a person's age. The following types of infectious organisms have been associated with septic arthritis:

  • Staphylococci. A common bacteria that often cause skin infections.
  • Haemophilus influenzae. Bacteria that can infect the larynx, trachea, and bronchi.
  • Gram-negative bacilli. A group of bacteria, including Escherichia coli, or E. coli
  • Streptococci. A group of bacteria that can lead to a wide variety of diseases.

The most prevalent sites of infection include the following:
