Efficacy of Genicular Block on Total Knee Arthroplasty Surgery

The aim of this study is to investigate the postoperative pain relieving effect of preoperative genicular block in total knee arthroplasty surgery. The main questions it aims to answer are: 1. Do visual analog scale (VAS) scores decrease in patients who underwent geniculate block? 2. Does opioid consumption decrease in patients who underwent geniculate block? Researchers will compare postoperative pain in patients who received genicular block with those who did not.One group of patients will be administered 0.25% bupivacaine with the geniculate block method. The other group will not undergo any intervention. Both groups will be administered intravenous morphine for postoperative analgesia.
