116 patients scheduled to undergo total hip arthroplasty (THA) were randomized to undergo the procedure with or without local infiltration analgesia (LIA) including 0.2% ropivacaine. The purpose of this study was to assess the effectiveness of LIA with ropivacaine (in addition to a multimodal analgesic regimen) on postoperative pain and opioid requirement following THA. The results of this study demonstrated that LIA with ropivacaine did not provide additional analgesic effect and that the consumption of opioids over the first postoperative day was comparable between groups.
