Outcome Measures

Primary Outcomes (1)

  • Blood loss

    Volume of blood loss in the suction drain device after TKA surgery

    up to 48 hours from the end of surgery, with drained volume registered every 6 hours.

Secondary Outcomes (2)

  • Thrombosis

    up to 15 days after surgery

  • Need for transfusion

    during or after surgery, during hospital stay (hospital discharge took place in four days, in average)

Study Arms (3)

Topical group

EXPERIMENTAL

Intervention: Tranexamic Acid - topical. Topical administration of a solution of 1.5 g of tranexamic acid (50 mg/ml, Transamin, Zydus Nikkho) diluted in 50 ml of saline (at 0.9%), sprayed over the operated area, covering it for 5 minutes, before the tourniquet release.

Drug: Tranexamic Acid - topical

Intravenous group

ACTIVE COMPARATOR

Intervention: Tranexamic Acid - intravenous Intravenous injection of 20 mg/kg of tranexamic acid, diluted in 100 ml of saline at 0.9%, administered with anesthesia in 10 minutes.

Drug: Tranexamic Acid - intravenous

Placebo

PLACEBO COMPARATOR

Intervention: intravenous injection of 100 ml of saline solution also administered with anesthesia in 10 minutes.

Drug: Placebo

Interventions

Tranexamic acid is an antifibrinolytic agent that decreases perioperative blood loss, because it inhibits fibrinolysis by competing with lysine molecule in coupling sites in fibrinogen. In this study arm, the drug is administered topically on the wound.

Also known as: trans-4-(aminomethyl)cyclohexanecarboxylic acid
Topical group

100 ml of saline solution administered with anesthesia during 10 minutes

Also known as: Saline solution
Placebo

Tranexamic acid is an antifibrinolytic agent that decreases perioperative blood loss, because it inhibits fibrinolysis by competing with lysine molecule in coupling sites in fibrinogen. In this arm, the drug is administered intravenously.
