About the trial
What the trial wants to find out
Total knee arthroplasty is associated with moderate to severe postoperative pain, which may delay mobilization and recovery. 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.
Read full original descriptionShow less
The 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.
The 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.
The 2 groups in the trial
- ACB + BiFeSTreatment being tested
Participants receive spinal anesthesia followed by an ultrasound-guided adductor canal block and a biceps femoris short head block using local anesthetic for postoperative analgesia.
Treatment: Adductor Canal Block and Biceps Femoris Short Head Block
- ACB + sham BiFeSExisting treatment, for comparison
Participants receive spinal anesthesia followed by an ultrasound-guided adductor canal block and a sham biceps femoris short head block using normal saline.
