Abstract

<p> <h3 id="x-x-sectitle0015"> Background </h3> <p id="x-x-abspara0010"> Administration of <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/tranexamic-acid" title="Learn more about Tranexamic Acid from ScienceDirect's AI-generated Topic Pages"> tranexamic acid </a> topically and intravenously has demonstrated effectiveness in decreasing <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/blood-transfusion" title="Learn more about Blood Transfusion from ScienceDirect's AI-generated Topic Pages"> blood loss and transfusion </a> rates. <h3 id="x-x-sectitle0020"> Methods </h3> <p id="x-x-abspara0015"> We randomized 131 patients undergoing primary <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/total-knee-arthroplasty" title="Learn more about Total Knee Arthroplasty from ScienceDirect's AI-generated Topic Pages"> total knee arthroplasty </a> to receive either intracapsular (69) or intravenous tranexamic acid (62). <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/postoperative-hemorrhage" title="Learn more about Postoperative Hemorrhage from ScienceDirect's AI-generated Topic Pages"> Postoperative blood loss </a> was calculated using the formula derived by Nadler et al. The number of units transfused was recorded, as well as length of hospital stay. <h3 id="x-x-sectitle0025"> Results </h3> <p id="x-x-abspara0020"> We found no statistically significant difference on calculated blood loss (postoperative day [POD] 1: 624 &plusmn; 326 vs 644 &plusmn; 292; <em> P </em> = .71, POD 2: 806 &plusmn; 368 vs 835 &plusmn; 319; <em> P </em> = .64, and POD 3: 1076 &plusmn; 419 vs 978 &plusmn; 343; <em> P </em> = .55). There was no difference in number of blood transfusions, length of stay, or complications. <h3 id="x-x-sectitle0030"> Conclusion </h3> <p id="x-x-abspara0025"> Intracapsular tranexamic acid is not inferior to intravenous tranexamic acid in decreasing blood loss and blood transfusion rate in primary total knee arthroplasty. </p> </p> </p> </p></p>
