Outcomes and Complications of Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Narrative Review

Hip arthroscopy has emerged as the primary surgical intervention for Femoroacetabular Impingement Syndrome (FAIS), a common cause of hip pain in young adults, particularly athletes. This narrative review examines the long-term outcomes, complications, and debates surrounding arthroscopic management of FAIS. Key findings include sustained improvements in patient-reported outcomes, return to sport, and functional recovery, particularly in younger patients and those with cam-type FAIS. However, some patients may eventually require total hip arthroplasty (THA), highlighting the variability in long-term durability. Complications, though infrequent, remain a significant concern, with the most common being transient neuropathy due to prolonged traction, heterotopic ossification, and iatrogenic cartilage damage. Recent studies emphasize the importance of patient selection, with younger patients, those with capsular closure, and those without pre-existing osteoarthritis showing superior outcomes. Additionally, sex-based differences suggest females may experience higher complication rates, though they often report better functional improvements post-surgery. Areas of ongoing debate include the role of labral debridement versus repair, the optimal management of mixed-type FAIS, and the potential benefits of adjunctive procedures such as ligamentum teres debridement. Future research should focus on refining surgical techniques and identifying patient-specific factors to further optimize outcomes. Despite its complexities, hip arthroscopy remains an effective treatment for FAIS, though individualized treatment plans are crucial to addressing the unique needs of each patient. By synthesizing current evidence, this review aims to guide clinicians in optimizing FAIS management and identifying areas for future research.
