Video Summary

This study evaluated factors influencing the risk of bone perforation during suture anchor placement in hip arthroscopy. Using saw bone models and clay soft tissue, researchers assessed drill portal choice (anterolateral, anterior, DALA), start point (on rim vs. 2mm off), drill guide type (straight vs. curved), and acetabular clock face position. Results showed the DALA portal had the lowest subchondral perforations, while the anterior portal had the highest cortical breaches, especially at 11–12 o'clock. Drilling 2mm off the rim reduced perforations. Understanding these risks aids surgeons in minimizing iatrogenic injury during acetabular labral repair.
