Tranexamic Acid Reduces Perioperative Blood Loss and Hemarthrosis in Total Ankle Arthroplasty.

Tranexamic acid (TXA) is an effective agent used for reducing perioperative blood loss and decreasing the potential for postoperative hemarthrosis. We hypothesized that patients who had received intraoperative TXA during total ankle arthroplasty (TAA) would have a reduction in postoperative drain output, thereby resulting in a reduced risk of postoperative hemarthrosis and lower wound complication rates. A retrospective review was conducted on 50 consecutive patients, 25 receiving TXA (TXA-TAA) and 25 not receiving TXA (No TXA-TAA), who underwent an uncemented TAA between September 2011 and December 2015. Demographic characteristics, drain output, preoperative and postoperative hemoglobin levels, operative and postoperative course, and minor and major wound complications of the patients were reviewed. Drain output was significantly less in the TXA-TAA group compared to that in the No TXA-TAA group (71.6 ± 60.3 vs 200.2 ± 117.0 mL, respectively, P < .0001). The overall wound complication rate in the No TXA-TAA group was higher (20%, 5/25) than that in the TXA-TAA group (8%, 2/25) (P = .114). The mean change in preoperative to postoperative hemoglobin level was significantly less in the TXA-TAA group compared to that in the No TXA-TAA group (1.5 ± 0.6 vs 2.0 ± 0.4 g/dL, respectively, P = .01). TXA is an effective hemostatic agent when used during TAA. TXA reduces perioperative blood loss, hemarthrosis, and the risk of wound complications.
