Chronic infectious arthritis develops over weeks and is usually caused by mycobacteria, fungi, or bacteria with low pathogenicity.

Chronic infectious arthritis accounts for 5% of infectious arthritis. It can develop in healthy people, but patients at increased risk include those with

A prolonged illness and lack of response to conventional antibiotics suggest a mycobacterial or fungal cause.

In chronic infectious arthritis, the synovial membrane can proliferate and can erode articular cartilage and subchondral bone. Onset is often indolent, with gradual swelling, mild warmth, minimal or no redness of the joint area, and aching pain that may be mild. Usually a single joint is involved.

Patients should have fungal and mycobacterial cultures taken of synovial fluid or synovial tissue, as well as routine studies. Molecular testing techniques may also be useful, especially for detecting mycobacteria.

Mycobacterial and fungal joint infections require prolonged treatment. Mycobacterial infections are often treated with multiple antibiotics, guided by sensitivity testing results.
