- Primary Outcome Measures
Name Time Method Main Objective: To demonstrate that tranexamic acid administered 30 minutes before ischemia further reduces free volume of postoperative bleeding in knee replacement (TKR) that administered before the surgical incision.;Secondary Objective: a) To assess whether a second additional dose of 10 mg / kg of tranexamic acid helps to reduce the total postoperative bleeding.<br>b) To assess the incidence of clinically significant thromboembolic events.;Primary end point(s): Perioperative bleeding in milliliters ( ml ) .<br>-Visible Losses : Total amount of bleeding in the draw ( until his retirement )<br>-Total estimated blood loss : according to formula described in the protocol.;Timepoint(s) of evaluation of this end point: Bleeding from surgery day untill 4th day.
- Secondary Outcome Measures
Name Time Method Secondary end point(s): -Adverse events related to treatment with antifibrinolytic : venous thrombosis, pulmonary embolism, arterial thrombosis, acute myocardial infarction , transient ischemic attack , cerebral vascular accident etc. <br>-Units of packed red blood cells transfused and patients transfused<br>-Total tranexamic acid (TXM) dose received;Timepoint(s) of evaluation of this end point: From first acid tranexamic dose untill +/-30 th day post surgery.
