Aims The aims of this study were to compare the efficacy and safety of intra-articular and intravenous (IV) tranexamic acid (TXA) in controlling perioperative blood loss in total knee arthroplasty (TKA) using a randomized, double-blinded equivalence trial. Patients and Methods A total of 182 patients aged between 45 and 75 years undergoing unilateral TKA at a tertiary centre were randomized to receive TXA, either 1.5 g intra-articularly after closure of the wound (n = 91) or two doses of 10 mg/kg IV (n = 91). The primary outcome measure was the reduction in the level of haemoglobin (Hb) in the blood on the fifth postoperative day. Secondary outcome measures were the total, visible, and hidden blood losses (TBL, VBL, HBL). We assumed equivalence of the primary outcome in both routes with a margin of ± 0.35gm/dl. Block randomization using computer-generated random numbers was used. The patients and the assessor of outcome were blinded. Results All patients completed the study. The mean difference in the reduction of the level of Hb between the two groups was -0.0055 gm/dl, with two-sided 95% confidence interval (CI) being -0.29 to 0.27, well within the predefined equivalence margin of ± 0.35gm/dl. The groups were comparable with regard to TBL, VBL, HBL, and complications. No patient needed a blood transfusion. Conclusion A single intra-articular dose and two IV doses of TXA give equivalent efficacy and safety in the management of blood loss at TKA. Cite this article: Bone Joint J 2018;100-B:152–60.

Abstract Background Intra-articular tranexamic acid (TXA) as an adjunct to intravenous TXA was reported to decrease perioperative blood loss during unilateral total knee arthroplasty (TKA). However, there have been no randomized controlled trials comparing intravenous versus combined intravenous and intra-articular TXA administration in patients undergoing simultaneous bilateral TKA. Methods We randomly assigned 77 patients with 154 involved knees undergoing simultaneous bilateral TKA to the intravenous TXA group (intra-articular placebo for each knee) or combined TXA group (1000 mg of intra-articular TXA for each knee) with 1:1 treatment allocation. In both groups, 1000 mg of TXA was given intravenously twice, just before surgery and 6 h after the initial administration. Other perioperative medications, surgical procedures, and blood management strategies were the same for all patients. The primary outcome was perioperative blood loss calculated from blood volume and change in hemoglobin from preoperative to postoperative day 3. Results Intention-to-treat analysis showed no statistically significant differences in perioperative blood loss until postoperative day 3 (1067 ± 403 mL in the intravenous TXA group vs. 997 ± 345 mL in the combined TXA group [95% CI, − 240 to 100 mL], P = 0.42). No patients required allogenic blood transfusion. The incidence of thrombotic events did not differ between groups (12% in the intravenous TXA group vs. 9% in the combined TXA group; P = 0.73). Conclusions The addition of intra-articular TXA did not reduce perioperative blood loss in patients undergoing simultaneous bilateral TKA compared with placebo.

AbstractBackground: The use of a tourniquet during total knee arthroplasty (TKA) continues to be a matter of debate. Advantages of tourniquet use include improved visualization, decreased intraoperative and total blood loss, and possibly decreased transfusion requirement. However, the recent widespread adoption of antifibrinolytic therapy with tranexamic acid (TXA), may negate these benefits. The purpose of this study was to evaluate perioperative blood loss and transfusion requirement with two different tourniquet application strategies, and surgery without the use of a tourniquet during routine, primary cemented TKA.Methods: A retrospective cohort study was performed of 300 patients undergoing TKA at a single institution after the implementation of a routine intravenous TXA administration protocol and consisted of three groups based on tourniquet usage: tourniquet inflation before incision and deflation following cement hardening (TQ), tourniquet inflation prior to cement application and deflation following hardening (Partial TQ), and no tourniquet usage (No TQ). Each group consisted of 100 consecutive patients. Perioperative blood loss, change in hematocrit and transfusion requirement were compared between groups. Results: Total blood loss (estimated blood loss and drain output) was lowest in the TQ group, however this was only due a slight decrease in intraoperative estimated blood loss. There was no difference in post-operative drain output, or change in hematocrit levels from preoperative values. There were no transfusions in the Partial TQ and No TQ groups, whereas there were 5 transfusions in the TQ group.Conclusions: In the era of routine TXA administration during TKA, tourniquet usage does not appear to have a benefit in regards to perioperative blood loss or transfusion requirement.
