The goal of this study was to determine the disease specificity and responsiveness of the Western Ontario Rotator Cuff Index (WORC). Responsiveness, two cut-off points of the minimal important change, the area under the curve, standard error of measurement, the minimal detectable change and the standardized response mean were determined. Patients undergoing a rotator cuff repair need to improve more than 35 points to be considered clinical importantly improved. The WORC is disease specific and has a high responsiveness in patients undergoing rotator cuff repair and patients with disease of the rotator cuff without rotator cuff tears.

Background: Tranexamic acid (TXA) use has become the gold standard in total joint arthroplasty to limit intraoperative blood loss and transfusion rates. More recently, the indications for TXA have expanded to knee and shoulder arthroscopy with promising early results. However, the effectiveness of TXA during arthroscopic rotator cuff repair (RCR) is unclear.

Purpose: Arthroscopic rotator cuff repair (ARCR) commonly results in significant postoperative pain. Adjuncts like dexamethasone (DEX) and tranexamic acid (TXA) are used to enhance postoperative recovery. This study aimed to determine whether the combined application of TXA and DEX could improve postoperative recovery during the first 24 hours in ARCR patients.

Background: Poor sleep quality due to nocturnal pain is increasingly reported as a major symptom in several shoulder pathologies. Sleep disturbance has been reported in up to 89% after rotator cuff tears and is frequently reported as the primary reason for referring patients to surgery. As a result, it is important to understand the impact of shoulder surgery on a patient's sleep quality.

Background: The underlying shoulder pathology in radiographic superior escape of the humeral head and association between acromiohumeral interval (AHI) on radiographs and magnetic resonance imaging (MRI) are poorly understood.

Methods: A retrospective review of shoulder radiographs and MRI scans was undertaken. AHI was measured using both modalities.
