The entry of bacteria and other organisms into the bloodstream can result in septic arthritis, or infection in the joint.
Infection may affect one or more joints, resulting in serious inflammation, pain and damage to the joint structures. Typically the knees are affected, however the hips, ankle, wrist, elbows and shoulder may also be affected.
Young children and older adults are most likely to develop septic arthritis. To treat septic arthritis and limit joint damage, strong antibiotics are required and the joint may need to be drained of infected fluid.
