Ultrasound-guided injection with hyaluronic acid in hip osteoarthritis: efficacy and safety in a real-life setting.

Our data suggest that HA-USGIAI may be an effective and safe treatment for moderate hip OA with short- and medium-term benefits. Key Points • US hip evaluation before interventional maneuvers may identify capsular distension suggestive for concomitant septic involvement, microcrystal arthropathy or incipient hip osteonecrosis. • USGIAI may be fundamental to achieve an efficacious and safe injection. • HA-USGIAI may be an effective and safe treatment for moderate hip OA with short- and medium-term benefits.
