Key result
Ultrasound detects tenosynovitis in ~56% of JIA children with ankle swelling, often without active joint synovitis.
Why the study?
The role of musculoskeletal ultrasound in juvenile idiopathic arthritis remains controversial, despite growing evidence for its utility, particularly in diagnosing tenosynovitis.

What is the prevalence of tenosynovitis detected by musculoskeletal ultrasound in patients with Juvenile Idiopathic Arthritis and ankle swelling?
Musculoskeletal ultrasound reveals that over half of JIA patients with ankle swelling have tenosynovitis, often without active joint synovitis, which responds well to biological therapy.
Paolera et al. (2022) conducted a cross-sectional in Juvenile Idiopathic Arthritis with Ankle Involvement (n=48). Musculoskeletal ultrasound was evaluated on Detection of tenosynovitis. Musculoskeletal ultrasound detected tenosynovitis in 56% of children with juvenile idiopathic arthritis and ankle swelling, with 48% of these lacking sonographic signs of active joint synovitis.
