Septic Arthritis

Septic arthritis is an infection within a joint, in which microorganisms reach the joint space and cause inflammation. It usually affects a single joint, such as the knee, hip, or shoulder.

How the infection arrives: the germs can reach the joint through the blood, through a nearby wound, or after certain procedures.

What is usually noticed:

• Intense pain in the joint
• Swelling and warmth in the area
• Difficulty moving the joint
• A sense of general malaise

When to seek care and with whom? Because this is a condition that can damage the joint, a very painful, warm, and swollen joint warrants prompt review. The internist and the rheumatologist guide the study of these joint infections; it is worth having a professional evaluate it promptly.
