Analgesic efficacy of selective tibial nerve block versus partial local infiltration analgesia for posterior pain after total knee arthroplasty: a randomized, controlled, triple-blinded trial.

研究概要

60 patients undergoing total knee arthroplasty (TKA) for posterior knee pain were randomized to receive either a tibial nerve block (TNB; n=30) or local infiltration analgesia (LIA) of the posterior capsule (n=30). The primary outcome of interest was intravenous morphine consumption at 24 hours. Secondary outcomes of interest included morphine consumption at 6, 12, and 48 hours, range of motion (ROM), quadriceps muscle strength, distance walked, postoperative nausea and vomiting, incidence of pruritus, length of stay, and pain at rest and with movement on a Visual Analog Scale (VAS). All outcomes were similar between the two groups.
