Evaluation of the paraarticular soft tissues is of primary importance in diagnosing acute joint problems of the lower extremity in children. With trauma, soft-tissue changes can alert the radiologist to an underlying bony injury; while with acute infection or inflammation, they enable identification and differentiation of the early stages of septic arthritis from osteomyelitis. Some soft-tissue changes have been described; others are presented for the first time. Because the findings differ from joint to joint, each joint is discussed separately.
