Background: this research aimed to compare the different analgesia methods used in patients undergoing total knee arthroplasty (TKA), with a special focus on the association of postoperative peripheral blocks. Methods: prospective-quantitative study in elective TKA patients at the hospital, Santa Casa de Misericordia, in Juiz de Fora, MG (N = 100), between March and November 2024. The patients were operated on by the same orthopedic surgeon specializing in knee. The method of anesthesia and analgesia used was freely chosen by the anesthetist scheduled for the surgery in question. Results: (i) the independent variable “sex” presented a Pearson correlation t=32.42; sig. >0.00 for the use of opioids in TKA surgical procedures. (ii) This result was reinforced by the high rate of opioid application in female patients in the postoperative period (86%, M=1.49; SD=0.52). (iii) The anesthetic technique Morphine + ACB presented a probability of 64.20% of application among women, against only 15.20% of iPack + ACB and 2.5% of ACB among men. (iv) 85% of the results obtained through the application of the Visual Pain Scale/Visual Analog Scale for pain (VAS) were concentrated between “mild pain” (36%) and “moderate pain” 49%. Conclusion: The high rate of opioid application in female patients in the postoperative period was related to the low application of iPack+ACB block. The literature is ambivalent on suggesting that iPack reduces mild pain, improve motor functions and reduce opioid consumption, while other studies reached the opposite conclusion.
