Enthesitis-related arthritis (ERA) is a subtype of the autoimmune disease juvenile idiopathic arthritis.

The cause of enthesitis-related arthritis is currently unknown (idiopathic).

Signs and symptoms of enthesitis-related arthritis generally develop in late childhood or early adolescence and include pain, tenderness, and swelling in joints and at the enthesis (the point at which a ligament, tendon, or joint capsule attaches to the bone). The knee and the back of the ankle (at the Achilles tendon) are the most commonly affected parts of the body.

Treatment goals are to ease pain and inflammation, improve strength and flexibility, and prevent joint damage. Treatment usually includes medicines to ease inflammation and physical therapy.

Cosentyx is the first biologic approved for the treatment of enthesitis-related arthritis.
