What is Septic arthritis?
Septic arthritis, also called infectious arthritis, it is an infection of a joint by bacteria. Its commonest forms occur after a lung or skin infection, surgery on the joint or any of several venereal diseases. The condition is typically acute, causing severe joint pain, inflammation, redness, and in some cases fever and chills but may also become chronic. Septic arthritis may affect any joint but is most frequently found in the knee, hip, shoulder, wrist, elbow, and finger joints. Usually only one joint will be affected but, in some cases, there may be more than one.
The following may increase your risk factors:
Sickle cell disease
- Artificial joint implants
- Bacterial infection
- Chronic illness or disease

in children and adults:

The joints of your arms and legs are most commonly affected by septic arthritis. In rare cases other joints, such as those in your back, neck and head, may be affected.
