Oligoarticular refers to a type of arthritis that affects a limited number of joints, typically four or fewer. It is most commonly seen in children and is often associated with conditions like juvenile idiopathic arthritis. This form of arthritis can lead to joint pain, swelling, and stiffness, but it usually has a better prognosis compared to more severe forms of arthritis. In oligoarticular arthritis, the affected joints may vary from person to person. Commonly involved joints include the knees, ankles, and elbows. Early diagnosis and treatment are essential to manage symptoms and prevent long-term joint damage, often involving medications and physical therapy.
