Biceps Femoris Short Head (BiFeS) Block and Adductor Canal Block for Postoperative Analgesia Following Total Knee Arthroplasty

Condition(s) studied

Investigational drug(s) / intervention(s)

Procedure: Biceps Femoris Short Head Block: Patients will receive spinal anesthesia followed by ultrasound-guided Biceps Femoris Short Head (BiFeS) block using 25 mL of 0.25% bupivacaine and adductor canal block using 15 mL of 0.25% bupivacaine before surgery. Standard multimodal analgesia will be provided using intravenous paracetamol and dexketoprofen, along with postoperative patient-controlled analgesia with morphine for 24 hours.

Procedure: Spinal Anesthesia: Patients will receive spinal anesthesia without peripheral nerve block. Standard multimodal analgesia will be provided using intravenous paracetamol and dexketoprofen, along with postoperative patient-controlled analgesia with morphine for 24 hours.

Study summary

This prospective randomized controlled study aims to evaluate the effect of ultrasound-guided Biceps Femoris Short Head (BiFeS) block combined with adductor canal block on postoperative opioid consumption and pain control in patients undergoing elective total knee arthroplasty under spinal anesthesia.

A total of 60 patients aged 18-80 years with ASA physical status I-III scheduled for unilateral elective total knee arthroplasty will be randomized into two groups. The intervention group will receive spinal anesthesia followed by BiFeS block and adductor canal block before surgery, in addition to standard multimodal analgesia and postoperative morphine patient-controlled analgesia (PCA). The control group will receive spinal anesthesia and standard multimodal analgesia with postoperative morphine PCA without peripheral nerve block.

The primary outcome is total morphine consumption during the first 24 postoperative hours. Secondary outcomes include postoperative pain scores assessed by Numeric Rating Scale (NRS), time to first analgesic requirement, time to first foot movement, and Quality of Recovery-15 (QoR-15) scores.

Eligibility

Primary outcome measure(s)

• Total Morphine Consumption in 24 Hours — Within the first 24 hours after surgery
  Total cumulative morphine consumption measured from patient-controlled analgesia device during the first 24 postoperative hours.
