Hitherto, no study has compared blood loss (BL) after different thromoprophylactic regimes (TR). The objective of this study was to quantify and compare BL in total hip arthroplasty (THA) under three different TRs. Between September 2013 and July 2014, sixty primary, unilateral, same-implant THAs entered a randomised, double-blind clinical trial. The patients were randomised to receive manufacturers' recommended doses of enoxaparin, dabigatran or rivaroxaban. Complete blood counts were obtained preoperatively and on the third day postoperatively. BL was calculated according to the Nadler formula. We also evaluated the occurence of wound healing disturbances (WHDs). All data were analysed using R statistical software.Background
