a) Principal: To assess if the fibrin glue or the tranexamic acid reduce less than 20% the blood losses with respect to the habitual haemostasia in patients with arthroplasty total of knee.

Secondaries: To assess the treatment safety. To perform a cost- analyses.

Methods: Randomized, unicentric, and parallel clinical trial with four comparative groups: Tissucol® (fibrin glue), fibrin glue manufactured by the Cryoseal® system (Banc de Sang i Teixits de Catalunya), tranexamic acid and habitual haemostasia.

Nº of participant centres: 1. Random allocation will be centralised.

Main outcome: Blood losses (ml) in the post-operatory period collected by the habitual drain system.

Secondary outcomes: Proportion of patients with blood transfusion, complications of surgery wound, pre and post-operative haemoglobin, units of blood transfused, post-operative mortality, days of hospital stay, safety of interventions assessed.

Size sample calculation: The number needed of patients is 172 (43 per group) to demonstrate a 20% difference in the post-operative blood losses between the treatments assessed and the habitual haemostasia, with a statistical power of 80% and a 0.05 bilateral alpha, and a 20% of withdrawals.

Statistical analysis: The investigators will perform a comparison of outcomes through the "t" test, the Mann-Whitney test of chi square, depending of the evaluated outcomes, quantitative or ordinals or qualitative, respectively. The software used will be Statistical Package for the Social Sciences (SPSS) version 17.

Arms Assigned Interventions
Experimental: Tranexamic acid
Tranexamic acid is a synthetic derivative of the amino acid lysine. It inhibits fibrinolysis by blocking the lysine binding sites on plasminogen and facilitates the coagulation process.
Drug: Tranexamic Acid

Two dosage during the surgical intervention: the first dosage 15-30' before the leg ischemia and the second dosage at 60 -90' after the first dosage.

Each dosage: 2 ampoules of 500mg/5 mL/ampoule

Other Name: Amchafibrin
Experimental: Fibrin glue BSTC
It is homologous fibrin glue from a single blood donor.
Biological: Fibrin glue
Topical administration, before to close the surgical wound.
Experimental: Tissucol
It is fibrin glue commercialized from multiple donors.
Drug: Fibrin glue
Topical administration, before to close the surgical wound. Dosage: 2 mL.
Other Name: Tissucol
Habitual haemostasis
Electrocoagulation of blood vessels was performed during surgery in all patients (routine hemostasis)
Other: Habitual haemostasis
The surgical habitual haemostasis.
