Evaluation of the Therapeutic Effect of Local Application of Tranexamic Acid in Rotator Cuff Repair

This prospective randomized controlled trial aims to evaluate the efficacy and safety of intraosseous tranexamic acid administration during arthroscopic rotator cuff repair. Eligible patients undergoing arthroscopic rotator cuff repair will be randomly assigned in a 1:1 ratio to receive either intraosseous tranexamic acid or intraosseous normal saline placebo. Tranexamic acid will be administered at a dose of 15 mg/kg through intraosseous injection into the proximal humerus after anesthesia induction. The primary outcome will be intraoperative arthroscopic visual clarity assessed using a five-grade visual clarity scoring system during different surgical stages. Secondary outcomes will include irrigation fluid volume, operative time, and frequency of irrigation pressure adjustments. Safety outcomes will include perioperative complications and laboratory assessments. This study will determine whether intraosseous tranexamic acid can improve visualization of the arthroscopic surgical field and optimize surgical conditions during rotator cuff repair.

Preoperative Versus Postoperative Interscalene Block in Arthroscopic Rotator Cuff Repair

This study is evaluating whether the timing of an interscalene nerve block affects pain control and recovery after arthroscopic rotator cuff repair surgery. An interscalene block is commonly used to reduce pain after shoulder surgery. However, it is not known whether administering the block before surgery or after surgery provides better outcomes. Participants undergoing arthroscopic rotator cuff repair are assigned to receive the interscalene block either before the surgical incision or after completion of the procedure. The study compares postoperative pain levels, opioid medication use, length of hospital stay, and ultrasound imaging quality during block administration between the two groups. Functional recovery is also assessed using patient-reported outcome measures during follow-up. The investigators hypothesize that administration of the interscalene block before surgery may provide superior early pain control and reduce postoperative opioid requirements while maintaining similar functional outcomes compared with administration after surgery.

TASK-ORIENTED REHABILITATION AFTER ROTATOR CUFF SURGERY

Rotator cuff tears negatively affect shoulder stability, range of motion, and performance in daily activities. Postoperative rehabilitation is essential for improving functional recovery and quality of life; however, conventional approaches may not directly target meaningful activity performance. Task-oriented occupational therapy is a client-centered approach focusing on meaningful and goal-directed activities to enhance functional independence. This randomized controlled trial aims to investigate the effect of task-oriented occupational therapy on activity participation, occupational performance, satisfaction, and functional recovery after rotator cuff surgery. A total of 30 participants will be randomly assigned to either a task-oriented occupational therapy group or a conventional rehabilitation group. The intervention will be conducted twice weekly for 10 weeks, with 40-minute sessions based on individually prioritized activities identified using the Canadian Occupational Performance Measure. Outcomes will include occupational performance and satisfaction, goal attainment, shoulder function, quality of life, and patient satisfaction.
