Extra-articular Hip Endoscopy: Current Indications, Evidence, and Techniques.

Advances in hip arthroscopy have expanded its use beyond intra-articular pathology to include a range of extra-articular conditions (endoscopy) that affect the active adult population. These minimally invasive procedures now provide practical, evidence-based alternatives to open surgery. Endoscopic techniques allow targeted management of greater trochanteric pain syndrome, iliopsoas tendinopathy, extra-articular hip impingement, and gluteal and hamstring tears with reduced morbidity and faster recovery. The purpose of this review is to summarize the current indications, key surgical principles, and clinical outcomes for extra-articular hip endoscopy, emphasizing pearls and pitfalls relevant to the practicing orthopaedic surgeon.
