Dual Subsartorial Block: An Analgesic Technique Targeting the Popliteal Plexus of the Knee in Anterior Cruciate Ligament Reconstruction—A Case Series

This case series (n = 8) investigated the dual subsartorial block (DSB) for anterior cruciate ligament (ACL) reconstruction. DSB provided robust postoperative analgesia, with most patients reporting visual analog scale (VAS) scores below 4 (rest and movement) throughout the first 24 hours. Opioid consumption was exceptionally low, with 5 patients requiring no rescue opioids. Crucially, motor function was largely preserved: 6 patients achieved a 5/5 Medical Research Council (MRC) score, and 2 achieved 4/5. No block-related complications were observed. These findings strongly advocate DSB as a highly effective, motor-sparing regional anesthetic strategy, significantly optimizing patient recovery and reducing opioid burden post-ACL surgery.
