Pathophysiology
Bacteria are carried by the bloodstream from an infectious focus elsewhere, introduced by a skin lesion that penetrates the joint, or by extension from adjacent tissue (e.g. bone or bursae).
Microorganisms must reach the synovial membrane of a joint. This can happen in any of the following ways:
- Dissemination of pathogens via the blood, from abscesses or wound infections
- Dissemination from an acute osteomyelitic focus
- Dissemination from adjacent soft tissue infection
- Entry via penetrating trauma
- Entry via iatrogenic means
