Proximal Anterolateral Accessory Portal Use Improves Peripheral Compartment Access and Capsular Management with T-Capsulotomy

Abstract

One of the primary goals of hip arthroscopy for femoroacetabular impingement (FAI) syndrome is precise removal of pathologic FAI morphology while protecting and restoring the normal soft tissue anatomy. Adequate visualization is a key foundation of precise removal of FAI morphology and varying types of capsulotomies are frequently used to achieve necessary exposure. Anatomic and outcomes studies have influenced an increasing appreciation for repairing these capsulotomies. Thus one of the central technical challenges of hip arthroscopy is achieving both goals of capsule preservation and adequate visualization. Various techniques have been described, including suture-based capsule suspension, portal placement, and T-capsulotomy. The following technique describes how the proximal anterolateral accessory portal can be added to a capsule suspension and T-capsulotomy technique to improve visualization and facilitate repair.
