What Causes Septic Arthritis?
Septic arthritis usually happens when bacteria enter the joint, often through the bloodstream, a direct injury, or an infection nearby. The most common bacteria responsible is Staphylococcus aureus. It can also be caused by other microorganisms in certain situations, like in people with weakened immune systems or those who inject drugs.
Symptoms You Shouldn't Ignore
If you experience a hot, swollen, and painful joint, especially in the knee, it might be septic arthritis. Other common signs include fever, redness, and limited movement of the joint. These symptoms can develop quickly, so it's important to see a doctor as soon as possible.
Diagnosing the Condition
Doctors diagnose septic arthritis by analyzing joint fluid obtained through aspiration. This fluid is checked for bacteria, white blood cell count, and crystals to confirm the infection. Blood tests and imaging like X-rays or MRIs may also be used to support the diagnosis.
