Summary

The aim is to compare the postoperative analgesic effects of Adductor Canal and Biceps Femoris Short Head Blocks with Adductor Canal Block in patients undergoing Knee Arthroplasty surgery

Detailed description

Patients were divided into two randomized groups: Group 1 (ACB group, n=30) and Group 2 (ACB+BiFeS group, n=30). All patients will receive the same standard spinal anesthesia per hospital protocol. All blocks will be applied with the same ultrasonography and block equipment, and by the same physician. After the surgery, patients in Group 1 will receive Adductor Canal Block (ACB) with 20 mL of 0.25% bupivacaine. Patients in Group 2 will receive Adductor Canal Block with 20 mL of 0.25% bupivacaine and Biceps Femoris Short Head (BiFeS) with 20 mL of 0.25% bupivacaine. Routine analgesic procedure consisting of 3x400mg Ibuprofen will be followed postoperatively for 24 hours. Numeric Rating Scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hours after the surgery. Tramadol 1mg/kg IV will be administered as a rescue analgesic for all patients if NRS score is higher than 4. Total Tramadol consumption will be calculated.
