A review of viscosupplementation for osteoarthritis of the hip and a description of an ultrasound-guided hip injection technique.

Viscosupplementation of the hip for symptomatic osteoarthritis appears to be safe and effective in more than 25 yr of use in Europe. More than 11 studies suggest that viscosupplementation in the hip is as effective as viscosupplementation in the knee. It appears to be a safe and reasonable alternative to nonsteroidal antiinflammatory drugs or intra-articular steroids for the treatment of osteoarthritis pain. Viscosupplementation in the hip may delay the need for hip replacement surgery. Viscosupplementation in the hip appears to work better in patients with fewer radiographic changes of osteoarthritis. Placement of viscosupplement in the hip under real-time ultrasound or fluoroscopic guidance is safe and well tolerated. Hip joint communication with the iliopsoas bursa may be a factor in studies of the effectiveness of viscosupplementation in the hip.
