Options for complex anesthesia after primary total knee arthroplasty

Abstact. Primary total knee arthroplasty (TKA) is a traumatic surgical intervention and is accompanied by severe pain, which creates problems in anesthesia and postoperative analgesia.The aim of our study was: to determine the level of pain after the primary TKA, to determine the causes and test the complex of multimodal systemic therapy of pain and infiltration analgesia, as an approach to reducing pain in the early postoperative period.Materials and research methods. The first step was a retrospective analysis of the treatment of 2482 patients with primary TKA, from 2012 to 2017. The average age of the patients was 63.9 years, gender distribution: men were 514 (20.7%), women - 1968 (79.3%). The operations were performed under spinal anesthesia and standard multimodal drug therapy for pain in the postoperative period. The second stage was a prospective randomized study in which one group (40 patients) of patients in the postoperative period was anesthetized using local high-volume infiltration anesthesia, and a comparison group (40) who underwent traditional multimodal analgesia...
