A Study Comparing Pain Relief After Arthroscopic Knee Surgery Using Adductor Canal Block or Genicular Nerve Block

What this Trial Is About

Researchers are comparing the pain relief effects of two nerve block methods, Adductor Canal Block ACB and Genicular Nerve Block GNB, in adults aged 18 to 72 undergoing arthroscopic knee surgery under spinal anesthesia. The study aims to find out which block better reduces postoperative pain, opioid use, and improves patient satisfaction. Arthroscopic knee surgeries often cause severe pain during movement after surgery, which can delay rehabilitation and increase complications. Participants will receive either the ACB or GNB nerve block before their arthroscopic knee surgery under spinal anesthesia. Both procedures are performed preoperatively. The study is randomized and double-blinded, comparing these two active treatment groups. The effectiveness of each block will be measured by pain scores and opioid consumption during the first 24 hours after surgery. During the study, participants pain levels will be assessed using pain scores at specific times within 24 hours after surgery. Researchers will also monitor opioid use, blood pressure, heart rate, oxygen levels, time to first mobilization or exercise, and length of hospital stay up to 14 days postoperatively. The main outcome is the pain score effectiveness within the first 24 hours. Participants will be fully informed and monitored throughout the study.
