Overview

Septic arthritis occurs when bacteria or other microorganisms infect a joint, leading to rapid inflammation and damage. It most commonly affects large joints like the knee or hip. This condition is a medical emergency, as delayed treatment can result in permanent joint damage or spread of infection.
