NCT Number: NCT06909851
This prospective randomized study aims to compare the analgesic efficacy of Adductor Canal Block (ACB) and Genicular Nerve Block (GNB) groups to relieve postoperative pain in participants between ages of 18-72 undergoing arthroscopic knee surgery under spinal anesthesia. The main question it aims to answer is:
To demonstrate whether Adductor Canal Block or Genicular Nerve Block is more effective in postoperative analgesia in patients undergoing arthroscopic knee surgery based on pain scores, opioid consumption and patient satisfaction.
Arthroscopic knee surgeries cause severe pain especially with movement in the post-operative period. After surgery, the movements of the participants are severely restricted because of pain, which increases the possibility of complications and postpones post-operative knee exercises. In this study, the participants' pain status, VAS score, opioid consumption and patient satisfaction will be measured with a simple scoring system for 24 hours at predetermined time points and then compared. Both types of blocks have pain-relieving effects. This study will only investigate which one is more effective in reducing pain, and there will be no deficiency in relieving the pain of the participants.

Inclusion criteria
Exclusion criteria
Evaluation of postoperative analgesic effectiveness of ACB block in participants undergoing arthroscopic knee surgery under spinal anesthesia.
Evaluation of postoperative analgesic effectiveness of GNB block in participants undergoing arthroscopic knee surgery under spinal anesthesia.
Time frame: Postoperative 24 hours
Postoperative pain assessment is performed using the Numerical Rating Scale (NRS). Participants are asked about their rest pain at Baseline 0, postoperative 1st, 2nd, 4th, 6th, 12th, and 24th hours after applying a preoperative peripheral nerve block. With this method, participants rate their pain with a precise numerical value from 0 to 10. While zero(0) represents "no pain"; Ten (10) represents the opposite end of the pain continuum (e.g., "The most intense pain imaginable," "As intense pain as possible," "Maximum pain").
Time frame: Postoperative 24 hours.
After the surgery all patients will be given 4 times a day Paracetamol 1 gram. Patients who still have pain (NRS 4 or higher) will be given Tramadol 1 mg/kg (maximum 400 mg Tramadol daily). Postoperative 24 hours the amount of the rescue analgesic (Tramadol) will be noted.
Time frame: Postoperative 24 hours
Participants' blood pressure (mm/hg) will be monitored for 24 hours (Post op 1st, 2nd, 4th, 6th, 12th and 24th hours) postoperatively.
Time frame: Postoperative 14 days
Length of hospital stay will be noted.
Time frame: Postoperative 24 hours
First time of mobilisation/exercise will be noted.
Time frame: Postoperative 24 hours
After the surgery all patients will be given 4 times a day Paracetamol 1 gram. Patients who still have pain (NRS 4 or higher) will be given Tramadol 1 mg/kg (maximum 400 mg Tramadol daily). Postoperative 24 hours the time of the rescue analgesic usage (Tramadol) will be noted.
Time frame: Postoperative 24 hours
Participants' heart rate (bpm) will be monitored for 24 hours (Post op 1st, 2nd, 4th, 6th, 12th and 24th hours) postoperatively.
Time frame: Postoperative 24 hours
Participants' oxygen saturation levels (spO2 %) will be monitored for 24 hours (Post op 1st, 2nd, 4th, 6th, 12th and 24th hours) postoperatively.
