Answer

Arthralgias occur in 60-84% of patients with IgAV and are the presenting complaint in approximately 25% of children. The large joints (eg, the knees and ankles) are the ones most commonly involved, with pain and edema being the only symptoms; the wrists and fingers are less commonly involved. True arthritis does not occur, and joint effusions are rare. Generally, the arthritis resolves completely over several days without permanent articular damage.
