Editorial Commentary: Interportal Capsulotomy for Hip Arthroscopy in Patients With Borderline Hip Dysplasia May Result in Inferior Outcomes: Periportal Capsulotomy May Reduce Hip Capsular Damage.

Abstract

Management of the hip capsule remains an ongoing discussion in the field of hip arthroscopy. Interportal and T-capsulotomies remain the most common approaches to gain access to the hip during surgery, and biomechanical and clinical research supports repair of these types of capsulotomies. Less is known, however, about the quality of the tissue that heals at these repair sites during the postoperative period, particularly in the setting of patients with borderline hip dysplasia. The capsular tissue provides important joint stability to these patients, and disruption to the capsule can result in significant functional impairments. There is also an association between borderline hip dysplasia and joint hypermobility, which increases the risk of insufficient healing after capsular repair. Patients with borderline hip dysplasia show poor capsular healing after arthroscopy followed by interportal hip capsule repair, and incomplete healing results in inferior patient-reported outcomes. Periportal capsulotomy may limit capsular violation and improve outcomes.
