“…Nicholson et al 23 similarly performed a study of preoperative intravenous tranexamic acid administration in a total of 100 patients and found no significant benefit of tranexamic acid in the ability to maintain lower pump pressures or improve arthroscopic visualization, operative time, or pain scores at 24 hours after the surgical procedure. In contrast, Bildik and Pehlivanoglu 24 performed a study of intra-articular tranexamic acid involving 63 patients and found significantly better arthroscopic visual clarity, shorter operative time, and lower pain scores at 8 and 24 hours after the surgical procedure in the group that received tranexamic acid intra-articularly.…”
