Septic arthritis is an intensely painful infection in a joint. The joint can become infected with germs that travel through your bloodstream from another part of your body. Septic arthritis can also occur when a penetrating injury brings germs directly into the joint.
Infants and older adults are most likely to develop septic arthritis. The most common joints affected are the knees and hips. Septic arthritis can quickly and severely damage the cartilage and bone within the joint, so prompt treatment is crucial.
Treatment involves draining the joint with a needle or via an operation. Intravenous antibiotics also may be necessary to stop the infection.
