Preoperative and post-operative sleep quality evaluation in rotator cuff tear patients.

Purpose: The aim of this study was to examine the potential relationship between subjective sleep quality and degree of pain in patients with rotator cuff repair.

Methods: Thirty-one patients who underwent rotator cuff repair prospectively completed the Pittsburgh Sleep Quality Index, the Western Ontario Rotator Cuff Index, and the Constant and Murley shoulder scores before surgery and at 6 months after surgery. Preoperative demographic, clinical, and radiologic parameters were also evaluated.
