Purpose: The learning curve of a single surgeon performing hip arthroscopy is reported to be steep, but, to date, the inflection point after which procedures are more successful is still unknown. The aim of this study was to design a learning curve focused on clinical outcomes, complications and revision/conversion rates., Methods: Seventy-one hip arthroscopies performed for femoroacetabular impingement (FAI) by a single surgeon, with a minimum follow-up of 5 years, were considered. Demographics, intraarticular findings and operative and traction time were detailed. HOOS score, subjective outcomes, 30-day complication rates, complication rates, revision arthroscopies and conversions to hip arthroplasty were recorded., Results: The mean follow-up was 7.5 ± 1.8 years (range: 5-11). The progression of the learning curve implied a reduction in surgical time ( r : -0.847), traction time ( r : -0.806) and postoperative outcomes ( r  = 0.444). When the procedures were divided into three consecutive groups (25 vs. 25 vs. 21 procedures) or two consecutive groups (36 vs. 35 cases), the first group had a higher occurrence of 30-day complications ( p  = 0.002 and p  = 0.025, respectively) and the last group experienced a significant amelioration in terms of HOOS score between the preoperative and the postoperative condition ( p  < 0.001 and p  = 0.018)., Conclusions: The inflection point of the hip arthroscopy learning curve is between 25/36 procedures. The first arthroscopies were impacted by higher complications and lower clinical results but no higher rates of revision and conversion to arthroplasty., Level of Evidence: Level IV., Competing Interests: The authors declare no conflict of interest., (© 2025 The Author(s).
