Brief summary
Problem Suction drains during TKA present certain costs to the health system and requires additional nursing care. There is no clear evidence that supports their use, and no studies so far have compared blood loss in patients with or without drains when TA is administered during TKA. Hypothesis During total knee arthroplasty, the postoperative blood loss, measured by hemoglobin level, will be lower when no drains are used. Method * Randomized controlled trial * Monocentric, 3 surgeons * Randomisation by sealed envelopes
Detailed description
During total knee arthroplasty, the postoperative blood loss, measured by hemoglobin level, will be lower when no drains are used.
Interventions
Administration of IV tranexamic acid at the moment of anesthetic induction (1g) and at tourniquet release (1g), installing a suction drain
Sponsors

Eligibility
Inclusion criteria
* Unilateral primary total knee arthroplasty
