Background: A growing body of evidence has shown Tranexamic Acid (TXA) is effective in decreasing perioperative blood loss and transfusion requirements in both primary and revision joint arthroplasty. TXA is a synthetic drug which limits blood loss through inhibition of fibrinolysis and clot degradation. It helps reduce requirement of colloids and crystalloids and hence provides better haemodynamic stability. The aim of this study was to detect the effect of tranexamic acid on coagulation parameters and effect on bleeding in knee replacement surgeries performed under tourniquet.Methods: Patients undergone surgeries of Total Knee Replacement (TKR) performed under tourniquet were included in the study. A single dosage of 20 mg/kg per body weight of tranexamic acid was administered after application of a tourniquet. Three times blood sample was collected, and coagulation parameters were recorded and compared. The first sample was collected at the time of TXA injection and application of a tourniquet, second after 4 hours and third after 24 hours post TXA injection. Coagulation parameters noted were analyzed using Statistical analysis by SPSS software. All parameters were compared in relation to baseline i.e. at the time of TXA injection.Results: On comparison of demographic profile, morbidity, sofa score and hemodynamic parameters there was the insignificant difference (P > 0.05). Repeated measures of ANOVA at 95% Confidential Interval P value was 0.000 which is less than the significant level that is 0.05 so that value of Platelet Function (PF), Activated Coagulation Time (ACT) and Clot Rate (CR) at 0 hrs, 04 hrs and 24 hrs was statistically significant. Correlation between blood loss and difference of the value of ACT at 0 hrs and 04 hrs is a small negative correlation but statistically nonsignificant (P value is 0.359).Conclusions: After TXA administration there is a change in coagulation parameters like an Activated Coagulation Time (ACT), Platelet Function (PF), and Clot Rate (CR) measured at three intervals, hence it can be a guide to detect early derangement in the coagulation profile in a patient undergoing knee replace surgery. TXA correlation between blood loss with changes in parameters of coagulation i.e. ACT, PF and CR were noted but not significant.

Introduction:  Total knee replacement (TKR) is one of the most common surgeries in orthopedic field. Up to 1/3 of the patients require blood transfusion postoperative. Allogenic transfusion has many side effects. Tranexamic acid (TXA) is a synthetic antifibrinolytic agent. We explore the usage of TXA in reducing blood loss and transfusion rate by injecting it into the knee joint during surgery.  Materials and method: This is a retrospective study done in Hospital Tengku Ampuan Rahimah, Klang. Medical records of patient undergoing TKR between 1 January 2018 till 31 December 2018 were reviewed. Study sample was calculated as 90 patients and divided into 2 groups, one receiving TXA (study) and the other not receiving TXA (control). Post-operative hemoglobin levels and transfusion rate was recorded.  Results: 45 patients in study group (17 male, 28 female) had a mean age of 65.4 years old and 45 patients in control group (24 male, 21 female) had a mean age of 64.2 years old. Mean post-operative hemoglobin drop in study group was 1.08 g/dL vs 1.86 g/dL in control group. Repeated measure ANOVA determined a p value of 0.001 which shows a significant correlation. Total transfusion rate in study group was 1 vs 9 in the control group. Using chi-square test, the p-value was 0.007 which again shows a statistically significant result.  Conclusion: Intra-articular injection of TXA following TKR reduces blood loss and the need for blood transfusion without increasing any complication. This prevents many patients from undergoing a potentially hazardous blood transfusion. A routine usage of intra-articular TXA in patients undergoing TKR is recommended. However a large and well designed RCT is required to investigate the risk and benefits of TXA.

Introduction: The use of peri-articular (PA) tranexamic acid (TXA) and its efficacy in comparison with intra-articular (IA) tranexamic acid has not been well explored in literature. This retrospective cohort study aims to compare the effects of IA and PA TXA with analgesic components in reducing blood loss and improving immediate post-operative pain relief and functional outcomes in unilateral primary total knee replacement (TKA) patients. Methods: 63 patients who underwent a unilateral primary total knee replacement procedure were divided into 2 groups: 42 patients in the IA TXA delivery group, 21 patients in the PA TXA group. 1g of TXA was utilized for all patients. All patients had pericapsular infiltration consisting of 0.5ml of Adrenaline, 0.4ml of Morphine, 1g of Vancomycin, 1ml of Ketorolac and 15ml of Ropivacaine. Outcomes for blood loss, and surrogate markers for immediate functional recovery were measured. Results: 54.0% of the patients were female, 46.0% male. The mean drop in post-operative Hb levels in the PA and IA group was 2.0g/dL and 1.6 g/dL respectively, and statistically insignificant (p=0.10). The mean HCT drop in the PA and IA group was 6.1% and 5.3% respectively and statistically insignificant (p=0.58). The POD 1 and discharge day flexion angles, POD 1 and POD 2 VAS scores, gait distance on discharge, and length of hospitalization stay were largely similar in both groups. Conclusion: Our study shows that both IA and PA TXA with analgesic components are equally efficient in reducing blood loss and improving immediate postoperative pain relief and functional outcomes.

ABSTRACT Aim To study the efficacy of topical intraarticular vs intravenous tranexamic acid (TXA) in reducing blood loss following primary total knee replacement (TKR). Materials and methods A phase 3, single center, double blind and randomized controlled study was conducted in the Department of Orthopedics, Sri Ramachandra University, Chennai, Tamil Nadu. A prospective study of 100 patients lasted from July 2013 to July 2015. Results Postoperative transfusion rates were zero in both the groups (intraarticular and intravenous). The mean 48-hour drain collected is 285.6 ml in group A (intraarticular), while it is 325.8 ml in group B (intravenous); the mean drop in hemoglobin is 1.7 gm/dl in group A (intraarticular) while it is 2.4 gm/dl in group B (intravenous). Conclusion This study shows that topical intraarticular administration of TXA has better efficacy than intravenous TXA in controlling postoperative blood loss following primary uncomplicated TKR with no significant complications.

<p class="abstract"><strong>Background:</strong> Several techniques are available to minimize the likelihood of blood transfusion following total knee arthroplasty. Tranexamic acid, an inhibitor of fibrinolysis that blocks the lysine-binding site of plasminogen to fibrin has been reported to reduce intraoperative and postoperative blood loss in patients undergoing total hip and total knee arthroplasties with or without cement. The objective of this study was to assess the efficacy of antifibrinolytic treatment along with other measures like saline adrenaline infusion, no drain, no tourniquet and hypotensive anaesthesia in reducing perioperative blood loss during total knee replacement<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> Between January 2011 to January 2016,  seventy five consecutive patients who had given written informed consent, undergoing a TKR received tranexamic acid 15 mg/kg body weight intravenous 5 minutes before the skin incision and two doses afterwards (3 and 6 hours after the first dose respectively). TKR was performed in a routine fashion without tourniquet. The saline adrenaline (1:200000) was infiltrated into the skin subcutaneous tissue and capsule before skin incision. A routine closure was carried out without drain. Total blood loss including the hidden blood loss was calculated. All patients were monitored for anemia and postoperative thromboembolic complications.<strong></strong></p><p class="abstract"><strong>Results:</strong> The average total blood loss in study group is 433 ± 148 ml. This is much lesser than what other studies have reported. Mean reduction in hemoglobin levels (gm/dl) between preoperative and postoperative readings is 1.6 gm/dl. One patient had a postoperative DVT which was treated with rivaroxaban 20 mg OD for 6 weeks (oral anticoagulant)<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> Antifibrinolytic agents like tranexamic acid used along with other measures reported in this study produces a significant decrease in blood loss in patients undergoing total knee replacement<span lang="EN-IN">.</span></p>
