Abstract
Background and Aim: Total knee arthroplasty (TKA) is an effective treatment for end-stage knee arthritis, but the optimal management of postoperative pain remains controversial. Therefore, this study investigated the efficacy of different local anesthetic application methods on early, 1 st day pain control after TKA. Methods: A total of 200 patients who underwent unilateral TKA surgery with spinal anesthesia were randomly assigned into four different groups (50 in each) and were administered pain control by different peri-and post-operative regimens. Group A was the control group wherein no postsurgical analgesia was administered to assess spinal anesthesia efficacy; in Group B, only postsurgical one-shot femoral block was applied; in Group C, intraoperative periarticular local anesthetic was applied; in Group D, a combination of the one-shot femoral block and intraoperative periarticular local anesthetics were applied. Results: Group D patients experienced significantly better postoperative pain relief ( P Conclusion: The intraoperative periarticular application of local anesthetics in addition to one-shot femoral block is an efficient way of controlling postsurgical pain after TKA.
