Local infiltration analgesia followed by continuous infusion of local anesthetic solution for total hip arthroplasty: a prospective, randomized, double-blind, placebo-controlled study
J Bone Joint Surg Am. 2013 Nov 6;95(21):1935-41105 patients undergoing total hip arthroplasty (THA) were randomized to investigate the safety and efficacy of local infiltration analgesia alone or in combination with continuous infusion of local anaesthetic after total hip arthroplasty, compared to a placebo.
