The 23-point arthroscopic examination of the hip: basic setup, portal placement, and surgical technique.

The 23-point arthroscopic examination of the hip has been used for more than 400 arthroscopic hip procedures. It ensures that all components of the hip are carefully inspected and allows for proper documentation. It is vital that a precise knowledge of hip anatomy and common portal placement is coupled with proper patient selection, sound preoperative planning, and a consistent arthroscopic technique in order to maximize clinical outcomes. The 23-point arthroscopic examination of the hip uses 3 standard portals (anterior, anterolateral, and posterolateral) that provide a systematic method of examination of the key structures of the central and peripheral hip joint. The points are divided up into groups based on the portal through which they are viewed. The 23-point arthroscopic examination of the hip is reproducible, and offers some standardization within the evolving field of hip arthroscopy. It provides a consistent routine for hip arthroscopy that has yet to be published. Using this standardized examination can assist with the diagnostic accuracy of hip arthroscopy.
