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

Condition(s) studied

Investigational drug(s) / intervention(s)

Tranexamic Acid: Tranexamic acid (15 mg/kg) is administered through intraosseous injection into the proximal humeral cancellous bone after anesthesia induction before arthroscopic rotator cuff repair.

Normal Saline: Participants receive an equivalent volume of normal saline through intraosseous injection into the proximal humeral cancellous bone after anesthesia induction before arthroscopic rotator cuff repair.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Arthroscopic Visual Clarity Score — During arthroscopic rotator cuff repair surgery
  Intraoperative arthroscopic visual clarity will be assessed during different surgical stages, including glenohumeral joint debridement, acromioplasty, and rotator cuff repair. A five-grade visual clarity scoring system will be used: Grade 1: Extremely poor visualization due to severe active bleeding. The surgical field cannot be adequately visualized and the procedure cannot proceed normally. Grade 2: Poor visualization with substantial bleeding interference. Surgical manipulation is significantly affected and additional hemostatic procedures are required. Grade 3: Moderate visualization. Mild to moderate bleeding is present and partially interferes with visualization, but surgery can proceed after routine management. Grade 4: Good visualization. Only minimal bleeding points are present, with limited interference and no requirement for additional hemostatic intervention. Grade 5: Excellent visualization. The surgical field is clear with no visible bleeding points and optimal visua
