AbstractTotal knee arthroplasty (TKA) is associated with an increased need for blood transfusions and thus an increase in risks associated with blood transfusion such as transfusion reactions, infections, fluid overload, and altered mental status. Tranexamic acid (TXA) is an antifibrinolytic medication that can reduce perioperative blood loss in TKA. However, the best method of delivery has not been defined although topical intra-articular TXA (IA-TXA) may have a theoretical advantage as it is applied directly when and where it is needed to control bleeding. Blinded and nonblinded randomized controlled trials and case-controlled trials published since 2010 were found using database searches. Data were extracted and analyzed with the goal of discovering through meta-analysis if IA-TXA reduces blood loss, blood transfusions, and without increasing adverse events, especially thromboembolic events, compared with placebo. Blood loss from suction drains and calculated total blood loss were significantly lower in the IA-TXA group. The frequency of blood transfusion and the number of units of blood transfused were significantly lower in the IA-TXA group. The risk of adverse events was not increased for IA-TXA versus placebo. Topical IA-TXA in primary, unilateral TKA successfully reduces blood loss and the frequency of blood transfusions. In addition, it does not appear to increase the risk of thromboembolic adverse events. There is need for further research to determine the optimal dosage and the preferred delivery system of IA-TXA in TKA.

Abstract Background There are various techniques to reduce blood loss in total knee arthroplasty (TKA), including the use of a tourniquet and tranexamic acid (TXA). In this study, we studied the combined effect of TXA with a tourniquet on blood loss in the setting of primary TKA. Methods Randomized controlled trials (RCTs) of nine treatment methods were included (placebo, intravenous [i.v.] TXA, topical TXA, i.v.-combined topical TXA, oral TXA, placebo + tourniquet, i.v. TXA +tourniquet, topical TXA + tourniquet, and i.v.-combined topical TXA + tourniquet). The patients were divided into eight groups according to the different treatment strategies, with 30 cases per group. The differences in the total blood volume, the number of patients transfused, the hemoglobin before and after the operation, and complications after the operation were compared. Results Totally 15 RCTs meeting our inclusion criteria were collected in this study. Compared with the placebo + tourniquet group, the i.v. TXA + tourniquet group displayed lower hemoglobin reduction value, pulmonary embolism (PE) incidence, total blood loss, and blood transfusion risk; the topical TXA + tourniquet group showed reduced PE incidence, total blood loss, and blood transfusion risk, and the i.v.-combined topical TXA and i.v.-combined topical TXA + tourniquet groups showed decreased total blood loss and lower blood transfusion risk. Retrospective clinical study results also demonstrated that the efficacy of i.v.-combined topical TXA was the best. Conclusions Our meta-analysis indicates that i.v.-combined topical TXA provides a low total blood loss without increasing the blood transfusion risk in patients undergoing total knee replacement surgery.

<p class="abstract"><strong>Background: </strong>The study is to compare the immediate post-operative outcomes with use of intravenous (IV) tranexamic acid (TXA) versus IV and local TXA combination in primary unilateral total knee arthroplasty. Study comprised of 72 cases of tricompartmental knee primary osteoarthritis who have undergone unilateral total knee arthroplasty at Manipal Hospital, Goa from January 2016 to December 2018. The observations for each group was analysed and post op blood loss in drain, fall of haemoglobin levels and need of blood transfusion was recorded. The results were statistically compared. The mean blood loss fall in HB levels and need of blood transfusions revealed statistically significant differences.</p><p class="abstract"><strong>Methods:</strong> Total 72 patients diagnosed with primary tricompartmental osteoarthritis were divided into two groups retrospectively. Group 1 (IV only): 1 gm IV Tranexamic acid bolus 10 min before deflating the tourniquet.

Objectives: Total knee arthroplasty is associated with significant blood loss, necessitating blood transfusions. Due to the obvious risks and costs of allogeneic blood transfusions, techniques to minimize blood loss in surgery are needed. The objective of this study was to assess the efficacy of tranexamic acid treatment in reducing blood loss and blood transfusion requirements during total knee arthroplasty. Materials and Methods: A prospective, randomized, double-blind, parallel-group, non-crossover trial was carried out in Prathima Hospital, Karimnagar. The trial involved 28 ASA I and II patients undergoing unilateral knee arthroplasty, 14 in each of the control and study groups. In the study group, a 10 mg/kg bolus of tranexamic acid was administered slowly IV 30 min before tourniquet deflation, followed by a 1 mg/kg/hr infusion for 12 h, compared to the standard medical treatment in the control group. Total blood loss during and after surgery was compared between the two classes. We also compared the hemoglobin drop after surgery, the number of people who needed blood transfusions, and the number of units needed between the two classes. Any complications were also reported. Results: Total blood loss in the tranexamic acid group was 543.3 ± 184.85 versus 685.83 ± 176.74, a statistically significant difference (P < 0.05). Intraoperative blood loss was comparable, but post-operative blood loss was significantly lower in the tranexamic acid group (389.16 ± 174 ml vs. 514.36 ± 143.89 ml), indicating that it was statistically significant (P < 0.05). There were no complications reported from any of the groups. Conclusion: Tranexamic acid is an effective strategy for minimizing overall blood loss and blood transfusions in patients undergoing total knee arthroplasty.
