- Reactive arthritis (synonym: postinfectious arthritis / joint inflammation) – second disease after gastrointestinal (gastrointestinal tract concerning), urogenital (urinary and genital organs concerning) or pulmonary (lungs concerning) infections; refers to an arthritis, where pathogens in the joint (usually) can not be found (sterile synovialitis).
