This prospective observational study aims to investigate the effect of preoperative central sensitization on postoperative clinical outcomes in patients undergoing arthroscopic rotator cuff repair. Central sensitization, characterized by an increased responsiveness of the central nervous system to pain stimuli, has been associated with persistent pain and poor functional recovery in various musculoskeletal disorders. However, its impact on outcomes following arthroscopic rotator cuff repair has not been fully elucidated.
Adult patients diagnosed with a rotator cuff tear by clinical examination and magnetic resonance imaging (MRI) and scheduled for arthroscopic repair will be enrolled. Preoperative central sensitization will be assessed using the Central Sensitization Inventory (CSI), while pain intensity and shoulder function will be evaluated using the Visual Analog Scale (VAS) and the Shoulder Pain and Disability Index (SPADI), respectively. Clinical assessments will be performed preoperatively and at postoperative 3 months. The study aims to determine whether preoperative central sensitization is associated with postoperative pain and functional recovery after arthroscopic rotator cuff repair.
