title: Monoarticular Arthritis.
abstract: Monoarticular arthritis is inflammation characterized by joint pain, swelling, and sometimes periarticular erythema. Although chronic causes are seen, the onset is often acute. An infected joint can quickly lead to permanent damage, making it a medical emergency. However, acute gout presenting as monoarticular arthritis is often so uncomfortable it requires urgent attention. Monoarticular crystalline arthritis is common and a septic joint is a medical emergency so it is no surprise that these diagnoses come to mind with complaint of inflammation in 1 joint. However, there are many causes of monoarticular arthritis that clinicians must consider.
