Evaluate the pharmacokinetic profile of tranexamic acid injected intra-articularly with or without adrenaline, in a population of patients undergoing knee replacement.
Orthopedic population, especially during a knee surgery, is at risk of significant bleeding and blood transfusion in the perioperative period. Tissue damage is associated with the activation of a cascade of mechanisms, in which the activation of the fibrinolyse plays an important role. This is why anti-fibrinolytic agents are regularly used in this context to reduce the perioperative bleeding and the use of blood transfusions.
In the majority of cases, tranexamic acid, an analogue agent of lysine, is administered by an intravenous injection and more recently, by an intra-articular injection.
Several questions however remain unanswered.
The efficacy, safety and better administration route of the tranexamic acid remain unknown when injected intra-articularly. The goal of this study is to realize the first pharmacokinetic study after an intra-articular injection of tranexamic acid, alone of along with adrenalin, in a knee neo-articulation.

| The pharmacokinetic profile of tranexamic acid | Blood sampling will be performed to establish the pharmacokinetic profile of tranexamic acid. T0 will be defined as the injection time of tranexamic acid. The first blood sampling (T1) will be made 5 minutes after, with the garrot still in place. The garrot will then be loosened and the following blood samplings will take place at 1 minute, 5 minute, 15 minutes, 30 minutes, 1h, 2h, 4h, 8h, 12h and 24h after garrot loosening. 1ml of blood will be taken at each blood sampling. The blood will be placed in a tube suited for chemistry analysis (green tube with gel) and sent directly to the laboratory for analysis. | 24h |
| Measure | Description | Time Frame |
|---|---|---|
| Knee diameter | This will be part of the semi-quantitative evaluation of the knee bleeding. The diameter of both knees (the one undergoing surgery and the untouched one) will be measured before and after surgery. | 12h |
| Net weight of the compresses |
