ABSTRACT
PURPOSE: Although tranexamic acid (TXA) is being increasingly used in orthopedic arthroplasty and lower-extremity arthroscopic procedures, its use in arthroscopic rotator cuff repair (ARCR) is less widely reported. The aim of this study was to evaluate the clinical effectiveness and safety of TXA administration in ARCR. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to compare clinical outcomes in patients who underwent ARCR with or without TXA. Literature was retrieved using the Cochrane Library, MEDLINE, PubMed, and Embase electronic databases. The primary outcome of this study was visual clarity. Secondary outcomes contained total operative time, postoperative pain score, amount of blood loss, shoulder swelling (change in shoulder circumference), volume of irrigation fluid, number of adjustments of the pump pressure for irrigation, and adverse cardiovascular events. RESULTS: Seven studies (3 and 4 with level I and II evidence, respectively), which included 272 and 265 patients who underwent arthroscopy with and without TXA, respectively, met the eligibility criteria. Pooled analysis showed significant improvements in visual clarity (mean difference, 9.10%; 95% CI, 4.05-14.15; P = .0004) and total operative time (mean difference, -11.24 minute; 95% CI, -19.90 to -2.57) associated with perioperative TXA application. None of the trials reported adverse events and complications associated with TXA. CONCLUSION: The best available evidence indicates that TXA administration could significantly improve arthroscopic visual clarity and effectively save operative time in ARCR without increasing the incidence of adverse events. Furthermore, the optimal dose, route, and timing of TXA application in ARCR surgery remains to be validated by future high-level evidence studies.
