We describe an arthroscopic technique for the treatment of labral pathology and femoroacetabular impingement that provides excellent access to the central and peripheral compartments while preserving the biomechanically crucial components of hip joint stability. The hip capsule and the ligaments within it have been shown to be integral to hip biomechanical stability. Other popular techniques such as interportal and T-capsulotomy inherently damage the capsuloligamentous complex of the hip and can be associated with postoperative gross instability, micro-instability, heterotopic ossification, and seroma. Capsular closure may mitigate some of these effects but has been associated with capsular insufficiency and requires postoperative restrictions that can be prolonged. Our surgical technique focuses on careful portal placement, replacement when necessary, use of a switching stick to maximize peripheral compartment visualization, and joint access in the most minimally invasive manner while avoiding complications associated with extended capsulotomy. The objective of this Technical Note is to describe a technique by which full access to the joint can be obtained while not disrupting the biomechanics of the joint capsule.
