Brief Summary
Total knee joint replacement surgery can lead to significant blood loss, which can affect recovery after surgery. Tranexamic acid (TXA) is a medication which stops the breakdown of blood clots and therefore prevents blood loss. The optimal use of TXA remains a point of debate. Growing interest in the topical application of TXA (directly into the surgical wound) has been suggested as an alternative way of administering TXA, and may demonstrate similar effectiveness as when it is given intravenously. Therefore, this multicentred, randomized controlled trial, aims to investigate the safety and effectiveness of both topical and intravenous administrations of TXA in total knee joint surgery. The investigators predict that both routes of administration will demonstrate similar results when compared to placebo.

Outcome Measures
Primary Outcomes (1)
Blood Loss
The loss of haemoglobin (Hb) was then estimated according to the formula: Hb(loss) = Blood volume (BV) x (Hbi-Hbe) x 0.001+Hbt where Hb (loss) (g) is the amount of Hb lost, Hbi (g/L) the Hb concentration before surgery, Hbe (g/L) is the Hbe concentration on the third day after surgery, and Hbt (g) is the total amount of allogeneic Hb transfused. A unit of banked blood is considered to contain a minimum of 40g Hb (Blood component data sheet, New Zealand Blood Services \[NZBS\]). All units of blood are processed and stored in a nationally standardised manner. The blood loss (ml) was related to the patient's preoperative Hb value (g/L): Blood loss =1000 x Hb(loss) /Hbi

Control
PLACEBO COMPARATORApplication of 20ml of normal saline (NaCl 0.9%) topically after implantation of prosthesis and left to sit for two minutes, excess carefully suctioned followed by standard closure with no drains; application of 15ml of normal saline intravenously at the same time prior to release of tourniquet.
Topical
EXPERIMENTALApplication of 1.5g in 20ml tranexamic acid topically after implantation of prosthesis with excess carefully suctioned followed by standard closure with no drains; application of 15ml of normal saline intravenously at the same time prior to release of tourniquet.
Systemic
EXPERIMENTALApplication of 20ml of normal saline topically after implantation of prosthesis with excess carefully suctioned followed by standard closure with no drains; Application of tranexamic acid intravenously (1.5g/15ml) at the same time prior to release of tourniquet
