Multimodal analgesia including regional anesthesia techniques is widely used to improve outcomes. The adductor canal block (ACB) provides anteromedial knee analgesia but may not adequately cover the posterolateral region.\n\nThe biceps femoris short head (BiFeS) block is a novel motor-sparing regional anesthesia technique targeting the posterolateral capsule of the knee. This randomized controlled trial aims to compare the analgesic efficacy and functional outcomes of ACB combined with BiFeS block versus ACB alone in patients undergoing total knee arthroplasty.\n\nThe primary outcome is posterior knee pain at postoperative 6 hours. Secondary outcomes include pain scores within 48 hours, opioid consumption, early and late functional recovery, and opioid-related adverse effects.",[76],"Total Knee Arthroplasty",[76,24,29,78,79,80,81],"Postoperative Pain","Functional Recovery","Opioid Consumption","Knee Osteoarthritis","NOT_YET_RECRUITING","2026-04-29",{"date":85,"type":86},"2026-05-05","ACTUAL",{"date":88,"type":70},"2026-05-15",{"date":90,"type":70},"2027-02-15",{"name":5,"class":6},1]
