60 Milliliters(ml)Normal saline (0.9% sodium chloride) will be applied by soaking the knee cavity for at least 3 minutes before wound closure and then sucked away.
two-dose intravenous tranexamic acid will be applied as follow: 10mg/kg of Tranexamic Acid in 100 Milliliters(ml) normal saline (0.9% sodium chloride),the first dose 15' before the tourniquet deflation and the second dose at 180' after the first dosage
