Extra-Articular Hip Pathology & Procedures
AHIRF has played a leading role in advancing extra-articular hip surgery through dedicated research and innovation. This section features AHIRF's work on procedures addressing extra-articular pathology, including treatment of iliopsoas-related conditions, gluteus medius and minimus tendon tears, proximal hamstring injuries, and greater trochanteric pain syndrome (GTPS). By exploring and refining techniques for these often-overlooked sources of hip pain and dysfunction, AHIRF continues to improve outcomes for patients with complex extra-articular hip disorders.
