[Objective] To retrospectively analyze the author's initial cases of hip arthroscopy, and summarize the learning curve expe- rience for portal establishment, so as to provide a reference for the beginners. [Methods] From May 2016 to February 2019, 50 patients had hip arthroscopy performed consecutively, and the time consumed for establishment of anterolateral approach (AL) and mid- anterolateral portal (MA) were recorded. [Results] With the accumulation of cases, the time required for AL establishment decreased significantly (P＜ 0.05) , which in term of the learning curve tended to be stable after 20 initial cases, and became not statistically significant (P＞0.05) . In ad- dition, the elapsed time for MA establishment decreased significantly as case number accumulation (P＜0.05), however, the learning curve leveled off after the 35th case (P＞0.05) . [Conclusion] The establishment of portals is one of the key points of hip arthroscopy learning, and the establishment of anterolateral portal is relatively easy, while the mid-anterolateral portal is difficulty, requiring 35 cases to complete the learning curve.
