In the literature, we found several studies with a methodology similar to ours. In 2010, Wong et al. analysed 3 treatment arms (in the first arm, 1.5<span class="elsevierStyleHsp" style=""></span>g of TXA was administered; in the second, 3<span class="elsevierStyleHsp" style=""></span>g, and in the third group, placebo) and observed a reduction of 315<span class="elsevierStyleHsp" style=""></span>ml of blood loss on average in the first arm and 402<span class="elsevierStyleHsp" style=""></span>ml in the second arm, compared to the control group.<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">11</span></a> Subsequently, Konig et al.<a class="elsevierStyleCrossRef" href="#bib0190"><span class="elsevierStyleSup">12</span></a> and Georgiadis et al.<a class="elsevierStyleCrossRef" href="#bib0195"><span class="elsevierStyleSup">13</span></a> reported a reduction in blood loss of 353 and 231<span class="elsevierStyleHsp" style=""></span>ml on average, respectively. We believe that these results that are quantitatively greater compared to our study may be due to the methodology used in terms of surgical manoeuvres, which, given that they are not standardised, may lead to differences that are unrelated to the administration of the drug.<a class="elsevierStyleCrossRef" href="#bib0200"><span class="elsevierStyleSup">14</span></a></p><p id="par0095" class="elsevierStylePara elsevierViewall">As for savings in blood loss, the main effect of administering TXA is that it reduces the rate of transfusion. Different studies indicate that patients undergoing knee arthroplasty who receive this drug do not require blood transfusion after surgery.<a class="elsevierStyleCrossRefs" href="#bib0205"><span class="elsevierStyleSup">15–17</span></a> In our case, the transfusion rate was zero for both TXA-treated patients and the control group.</p><p id="par0100" class="elsevierStylePara elsevierViewall">Regarding the analysis of functionality, the interest lies in the fact that, by decreasing blood loss-related complications, rehabilitation does not have to be delayed because of said complications. Therefore, in 2018, Grosso et al.<a class="elsevierStyleCrossRef" href="#bib0220"><span class="elsevierStyleSup">18</span></a> proposed to analyse functional outcomes and early recovery among the participants who received intravenous TXA. To do so, 560 patients were randomised into two treatment arms; the first group received TXA and the second group received placebo. The result was that the subjects who were given TXA were able to walk more from the second day on. However, there was no difference on the VAS score. On the other hand, Serrano et al.<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">19</span></a> analysed post-surgical functional outcomes with the Knee Society Score (KSS) and differences were observed at six weeks after drug administration, but not at four months. In 2019, Hirose et al.<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">20</span></a> conducted an analysis of joint balance (JB) after intra-articular TXA administration following surgical wound closure. They achieved an improvement in JB on the fourth, tenth, and fourteenth day. However, there was no difference in the 10<span class="elsevierStyleHsp" style=""></span>m ambulation test, VAS, or muscle strength.</p><p id="par0105" class="elsevierStylePara elsevierViewall">Similar to Guerreiro et al.,<a class="elsevierStyleCrossRef" href="#bib0235"><span class="elsevierStyleSup">21</span></a> we found no significant differences in our study between the two groups with respect to time to onset of standing following surgery, VAS at one month postoperatively, and days of hospitalisation.</p><p id="par0110" class="elsevierStylePara elsevierViewall">In our opinion, these differences between the various studies in terms of functional outcomes are likely to be due to the analysis of multiple secondary variables. Therefore, a pre-study protocol is deemed fundamental to clearly define the primary endpoint, as well as the sample size.</p><p id="par0115" class="elsevierStylePara elsevierViewall">As for the possible adverse reactions of TXA administration, thromboembolic events are particularly relevant, as described in its technical data sheet.<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">22</span></a> However, in this clinical trial, no cases of thromboembolic events were reported in either of the two treatment arms. Other events related to the surgical technique, such as surgical wound dehiscence, haematoma requiring drainage, or bleeding that could not be controlled with conservative measures, were also not reported. Similar results were reached in studies by Konig et al.,<a class="elsevierStyleCrossRef" href="#bib0190"><span class="elsevierStyleSup">12</span></a> Wong et al.,<a class="elsevierStyleCrossRef" href="#bib0185"><span class="elsevierStyleSup">11</span></a> and Geordiadis et al.,<a class="elsevierStyleCrossRef" href="#bib0195"><span class="elsevierStyleSup">13</span></a> in which no increased incidence of thromboembolism or any other complication was observed when TXA was topically administered.</p><p id="par0120" class="elsevierStylePara elsevierViewall">A meta-analysis conducted in 2018<a class="elsevierStyleCrossRef" href="#bib0245"><span class="elsevierStyleSup">23</span></a> that included 73 clinical trials with a total of 6953 patients undergoing prosthetic knee surgery concluded that the overall incidence of venous thromboembolism was 2.1% in individuals who were given TXA versus 2% in the control group. However, these results should be taken with caution, inasmuch as clinical trials often select patients with strict inclusion criteria that do not reflect standard clinical practice, and exclude those who are at high surgical risk, as is the case in our study; this implies a lack of external validity. For this reason, Poeran et al.<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">24</span></a> conducted a retrospective analysis comparing the safety profile of TXA in 872,416 patients who underwent knee and hip replacement surgery in 510 hospitals in the United States. The study concluded that those who received TXA had a lower rate of thromboembolic complications (0.6% vs. 0.8%), as well as a decrease in acute renal failure (1.2% vs. 1.6%); the difference was significant. A similar result was obtained by Sabbag et al.<a class="elsevierStyleCrossRef" href="#bib0255"><span class="elsevierStyleSup">25</span></a> in their study, in which they observed that the administration of TXA in patients who had experienced an episode of thromboembolism did not increase the risk of recurrence of a new episode when they were treated with prosthetic knee surgery. In 2020, Porter et al.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">26</span></a> also analysed the safety profile of the drug in 22,491 prosthetic knee surgery recipients. Of the total number of patients, 5501 were at high thromboembolic risk (deep vein thrombosis, pulmonary thromboembolism, myocardial infarction, stroke, atrial fibrillation, coronary artery bypass grafting, cardiac stents). TXA was administered to approximately 50% of these patients without finding an increased incidence of thromboembolic events. The importance of the latter article is greater, given that it reflects the results of routine clinical practice, thereby increasing its external validity.</p><p id="par0125" class="elsevierStylePara elsevierViewall">Among the limitations of our study, we found that the sample may not be representative of the general population as it was conducted under ideal conditions, which decreases its external validity. On the other hand, the participation of up to four surgeons may have affected the blood loss results. Finally, it is worth mentioning that subjects have benefited from closer monitoring, which may have had a bearing on initiation of standing and length of hospitalisation.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Conclusions</span><p id="par0130" class="elsevierStylePara elsevierViewall">Topical administration of 3<span class="elsevierStyleHsp" style=""></span>g TXA in a single dose has proven to be safe and effective in our population.</p><p id="par0135" class="elsevierStylePara elsevierViewall">We believe that the rate of blood transfusion depends more on refined technique than on drug administration.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Future lines of research could focus on clinical trials with greater external validity as more information becomes available about the safety profile of TXA.
