 To ensure the double-blinding upset of this study, the 60 patients from the control group receive a solution of 1.5g TXA in 100ml 0.9NaCl, administered intravenously before closure of the incision. A dose of 3g TXA is applied intra-articular to the other group of 60 patients. The intra-articular injection is applied after THA, when the wound already has been closed. Two hours after wound closing, the surgical drain will be opened. The two hour wait after wound closing is proven most successful.
