What this trial studies

This prospective randomized study compares the effectiveness of two pain relief techniques, Adductor Canal Block (ACB) and Genicular Nerve Block (GNB), for patients aged 18-72 undergoing arthroscopic knee surgery under spinal anesthesia. The study aims to evaluate postoperative pain levels, opioid consumption, and patient satisfaction over a 24-hour period following surgery. Participants will be monitored for pain scores and overall satisfaction to determine which method provides better analgesia.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-72 undergoing arthroscopic knee surgery who are suitable for regional anesthesia.

Not a fit: Patients undergoing surgery under general anesthesia or those with chronic analgesic use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing knee surgery, potentially reducing opioid use.

How similar studies have performed: Previous studies have shown promising results with similar nerve block techniques for postoperative pain management, indicating potential success for this approach.
