Adductor Canal Block With or Without Biceps Femoris Short Head Block in Total Knee Arthroplasty
Effect of Adding a Biceps Femoris Short Head Block to an Adductor Canal Block on Postoperative Pain and Functional Outcomes After Total Knee Arthroplasty: A Randomized Controlled Trial
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.
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.

실험적: ACB + BiFeS
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.
|
Ultrasound-guided adductor canal block performed with injection of local anesthetic into the adductor canal to block the saphenous nerve and provide postoperative analgesia following total knee arthroplasty.
Ultrasound-guided biceps femoris short head block performed with injection of local anesthetic between the biceps femoris short head and femur to target the posterolateral innervation of the knee for postoperative analgesia.

활성 비교기: ACB + sham BiFeS
Participants receive spinal anesthesia followed by an ultrasound-guided adductor canal block and a sham biceps femoris short head block using normal saline.
|
Ultrasound-guided adductor canal block performed with injection of local anesthetic into the adductor canal to block the saphenous nerve and provide postoperative analgesia following total knee arthroplasty.
Sham ultrasound-guided biceps femoris short head block performed with injection of normal saline at the same anatomical location to maintain blinding without providing active analgesia.
