Beach-Chair Versus Lateral Decubitus Positioning for Arthroscopic Posterior Shoulder Labral Repair: A Retrospective Comparison of Clinical and Patient-Reported Outcomes.

Surgical positioning for arthroscopic posterior shoulder labral repair did not affect postoperative clinical and patient-reported outcomes. Both beach-chair and lateral decubitus position provided good outcomes for posterior shoulder labral repair, with an overall recurrence rate of 8.7%. Increased age was a weak independent risk factor for subjective recurrent instability.
