Brief summary
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.

Intervention model description
Patients who are admitted to the orthopedic and traumatology clinic and are scheduled for arthroscopic knee surgery will be informed and monitored prior to the operation under spinal anesthesia. Preoperatively, either Adductor Canal Block (ACB) (Group A) or Genicular Nerve Block (GNB) (Group B) will be applied. Randomization will be performed using a computer-based method (http://www.randomizer.org) with a 1:1 allocation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effectiveness on Pain Scores (NRS) | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Amount of rescue analgesia administration | 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. |
| Postoperative Blood pressure | 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. |
| First Time Of Mobilisation/Exercise | Postoperative 24 hours | First time of mobilisation/exercise will be noted. |
| Length of hospital stay | Postoperative 14 days | Length of hospital stay will be noted. |
| Postoperative heart rate | Postoperative 24 hours | Participants' heart rate (bpm) will be monitored for 24 hours (Post op 1st, 2nd, 4th, 6th, 12th and 24th hours) postoperatively. |
| Postoperative oxygen saturation levels | 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. |
| The Time of Rescue Analgesic | 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. |
