Causes 1

Septic arthritis occurs when microorganisms enter a joint and multiply within the joint fluid or tissues. Bacteria are the most common cause. Infection can reach a joint through the bloodstream, from an injury or surgery, or by spreading from nearby infected tissue. Existing joint disease or an artificial joint can increase susceptibility.
Infection

Risk Factors

Risk factors for septic arthritis include an artificial joint, recent joint surgery, injection drug use, bloodstream infection, weakened immunity, diabetes, rheumatoid arthritis, and other chronic illnesses. Older age and existing joint damage can also increase susceptibility. Any condition that allows microorganisms to enter the bloodstream can potentially contribute.

Diagnosis

Diagnosis is based on a patient's medical history, symptoms, physical examination and, when necessary, laboratory or imaging investigations.
Septic arthritis is diagnosed urgently using symptoms, physical examination, blood tests, imaging when appropriate, and analysis of joint fluid. A needle may be used to remove fluid from the affected joint for laboratory testing, including examination for microorganisms and inflammatory cells. Blood cultures may also help identify an infection that has entered the bloodstream.

Prevention

Key Prevention Tips
There is no guaranteed way to prevent septic arthritis, but prompt treatment of skin and other infections, good wound care, appropriate management of chronic illnesses, and proper care around joint surgery can reduce risk
People with artificial joints or weakened immunity should seek prompt medical attention for symptoms of infection
Prevention Guidance
There is no guaranteed way to prevent septic arthritis, but prompt treatment of skin and other infections, good wound care, appropriate management of chronic illnesses, and proper care around joint surgery can reduce risk.
