Efficacy of Two Unique Combinations of Nerve Blocks on Postoperative Pain and Functional Outcome After Total Knee Arthroplasty: A Prospective, Double-Blind, Randomized Controlled Study.
This study aimed to explore the efficacy of two unique combinations of nerve blocks on postoperative pain and functional outcome after total knee arthroplasty (TKA). ⋯ Adding ONB or ONB + LFCNB to ACB + IPACK can statistically reduce morphine consumption, improve early pain relief, and functional recovery. However, the absolute change in morphine consumption, VAS scores, and QoR-15 scores did not exceed the MCIDs. Based on our findings and considering the sample size of this study, there is not enough clinical evidence to support the triple or quadruple nerve block use within a multimodal analgesic pathway after TKA.
