The arthroscopic treatment of unidirectional anterior and posterior shoulder instability has been reported in the literature with promising results. Multidirectional instability (MDI) includes a spectrum of pathology with both traumatic and atraumatic components. Atraumatic MDI of the shoulder is an uncommon and difficult-to-diagnose condition that is often initially treated conservatively with rehabilitation. Outcomes of surgical stabilization of symptomatic multidirectional shoulder instability, refractory to nonoperative management, have been described by multiple groups of investigators, using a variety of open and arthroscopic surgical techniques, with good to excellent results being reported in 80% to 94% of cases.
The purpose of this study by Dr. Verma and his team was to analyze results of arthroscopic stabilization with labral repair in a subset of patients with multidirectional shoulder instability and frank labral tear.
