End-stage ankle arthritis is a disabling condition that may lead to poor quality of life and difficulties with activities of daily living.1 The associated mental and physical disability has been demonstrated to be as severe as in end-stage hip arthrosis.2 Operative treatment for symptomatic end-stage ankle arthritis includes arthrodesis or total ankle arthroplasty (TAA) in those refractory to nonoperative treatment.3 Newer generation implants have made TAA a more attractive option for both the surgeon and the patient.

Over the past decade, the utility of TAA has increased and attention has turned toward the management of perioperative factors that would maximize patient satisfaction and decrease the length of stay and complication rates, as well as hospital costs.4 Comprehensive literature on total knee arthroplasty (TKA) and total hip arthroplasty (THA) has demonstrated that the management of perioperative blood loss, specifically postoperative hemarthrosis, is a modifiable factor affecting patient recovery, complication rates, and hospital costs.5-8 Drain output has been used as a direct measure of intra-articular blood accumulation.9 Decreased drain output implies decreased hemarthrosis, which could potentially alleviate the pressure on the wound and decrease wound complications.

One of the major strategies that has been recognized for reducing blood loss and decreasing the potential for postoperative hemarthrosis is the use of intravenous (IV) or topical tranexamic acid (TXA).10,11 TXA is a synthetic antifibrinolytic medication that has been extensively used throughout the medical field since the 1960s to help control the bleeding cascade. This medication stabilizes clot formation without inducing a pro-coaguable state.12 Intraoperative administration of TXA has been shown to reduce drain output and decrease transfusion requirements after TKA and THA without an associated increase in patient morbidity and mortality.6,11,13-15

Currently, there is a lack of studies evaluating the utility of TXA during TAA. We hypothesize that compared with patients who had not received TXA, those who had received intraoperative TXA during TAA would have a reduction in postoperative drain output and therefore decreased hemarthrosis, lower wound complication rate, and a diminished change in preoperative to postoperative hemoglobin levels, reflecting a reduction in perioperative blood loss.

MATERIALS AND METHODS

This study was approved by the Institutional Review Board at the University at Buffalo, State University of New York. A retrospective chart review was conducted on 50 consecutive patients who underwent an uncemented TAA with the Salto Talaris total ankle prosthesis (Tornier, Inc) between September 2011 and December 2015. All surgeries were performed at 1 institution by a single fellowship surgeon trained in foot and ankle surgery through the anterior approach where a midline incision was made over the ankle. The interval between the tibialis anterior tendon and the extensor hallucis longus tendon was used. We had incorporated intraoperative TXA into the TAA surgical protocol at our institution in January 2014. We evaluated the first 25 consecutive patients who underwent TAA after TXA use began (TXA-TAA) and another 25 consecutive patients who underwent TAA before the routine use of TXA (No TXA-TAA). Inclusion criteria were patients who presented with pain, decreased function, and radiographic parameters of end-stage tibiotalar arthritis due to degenerative arthritis, rheumatoid arthritis, or posttraumatic arthritis who subsequently underwent a TAA. Exclusion criteria were patients with a contraindication for IV TXA use, a preexisting coagulopathy, or where drain output was not recorded. Contraindications for IV TXA use included patients with impaired renal clearance, recent cardiac surgery, myocardial infarction, ischemic stroke, or venous thromboembolism (VTE). Seven patients were ultimately excluded from this study based on the inclusion and exclusion criteria, 3 patients from the TXA-TAA group and 4 patients from the No TXA-TAA group.
