Comparison of Analgesic Effects of ACB Versus ACB Combined With BiFeS Block in Meniscopathy Surgery

Meniscopathy surgeries are commonly associated with moderate postoperative pain, particularly during early mobilization and rehabilitation. Inadequate postoperative analgesia may negatively affect functional recovery, delay ambulation, increase opioid consumption, and contribute to opioid-related adverse effects. Therefore, effective multimodal analgesic strategies are of considerable importance in patients undergoing arthroscopic knee procedures.

Adductor canal block (ACB) is a widely used regional anesthesia technique that provides effective analgesia while largely preserving quadriceps muscle strength. However, its limited effect on posterior knee capsule innervation may result in insufficient control of posterior knee pain. Recently, the biceps femoris short head (BiFeS) block has been described as a novel motor-sparing fascial plane block targeting the posterolateral knee capsule and may provide additional analgesic benefit when combined with ACB.

In this study, it was aimed to compare the postoperative analgesic efficacy of adductor canal block alone and adductor canal block combined with BiFeS block in patients undergoing surgery for meniscopathy.

Treatment and study plan

Adductor Canal Block Group

Procedure

Adductor canal block will be performed on the patients using 10 ml of 0.25% bupivacaine under ultrasound guidance.

Additionally, in the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.

Adductor Canal Block + BiFeS (Biceps Femoris Short Head) Block Group

Procedure

In the adductor canal block + BiFeS block group, adductor canal block will be performed using 10 ml of 0.25% bupivacaine, followed by BiFeS block using 20 ml of 0.25% bupivacaine under ultrasound guidance, with a total local anesthetic volume of 30 ml.

Additionally, in the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.

Control Group

Procedure

In the postoperative period a paracetamol dose of 1 g every 8 hours and a dexketoprofen dose of 50 mg twice daily were administered iv for multimodal analgesia.

Primary outcomes

  1. Pain Scores

    Time frame: On the operation day

    Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 100 (worst pain). Pain assessment will be done at 0st, 1st, 2nd,4th, 12th, and 24th hours after surgery.

Secondary outcomes

  1. Total Postoperative Morphine Consumption During the First 24 Hours After Surgery

    Time frame: On the operation day

    Total Postoperative Morphine Consumption During the First 24 Hours After Surgery
