Medium-term results of arthroscopic treatment for femoroacetabular impingement

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.
