What is it?

Reactive arthritis is caused by an infection in somewhere else in the body, such as the intestine, genitals, or urinary tract.
Knees, ankles, and feet are usually affected by this condition. The urethra (a tube that carries urine out of the body) and the eyes can also be affected by inflammation. Previously, reactive arthritis was sometimes called Reiter's syndrome.
