This research aim to improve postoperative outcome in total hip arthroplasty(THA) by using local mixture infiltration as bupivacaine + NSAID + epinephrine + tranxemic acid. In the present time these mixture components has shown to improve THA outcome by aspect of postoperative pain control, postoperative opioid consumption, postoperative bleeding, LOS and postoperative rehabilitation without increasing complication but the accuracy of infiltration technique which gives the best outcome has not been yet discovered.Recently study by Hashimoto et al has risen that these technique can be administrated by both periarticular and intra-articular approach.By considering the complexity of human anatomy around the hip tissue we assume that the intra-articular(transarticular) may given equivalence (may be better) outcome with lowering procedural related complication comparing to periarticular infiltration approach.
