INTRODUCTION Femoroacetabular impingement (FAI) is a dynamic pathomechanical process of the femoral head-neck junction. Arthroscopic surgery for FAI has increased exponentially in the last decade, and this trend is expected to increase. SOURCE OF DATA Recent published literatures. AREAS OF AGREEMENT FAI promotes quick rehabilitation and low complication rates in the short-term follow-up. AREAS OF CONTROVERSY Despite the growing interest on arthroscopic surgery for FAI, current evidence regarding the medium- and long-term role of arthroscopy are unsatisfactory. GROWING POINTS Systematically summarize current evidences, analyse the quantitative available data and investigate the medium- and long-term outcomes of arthroscopic surgery for FAI. AREAS TIMELY FOR DEVELOPING RESEARCH Arthroscopic surgery achieves very satisfactory outcomes for patients with FAI at a mean follow-up of 4 years.
