Comparison of Analgesic Effects of Adductor Canal Block Versus Adductor Canal Block Combined With BiFeS (Biceps Femoris Short Head) Block in Meniscopathy Surgery

What this Trial Is About

Meniscopathy surgeries often cause moderate pain after the operation, especially during early movement and rehabilitation. Poor pain control after surgery can slow recovery, delay walking, increase the need for opioid pain medication, and cause opioid-related side effects. Researchers are comparing two types of nerve blocks to improve pain relief after arthroscopic knee surgery: the commonly used adductor canal block (ACB) and a combination of ACB with a newer biceps femoris short head (BiFeS) block that targets additional nerves around the knee. The study compares three groups of patients undergoing meniscopathy surgery. One group receives an adductor canal block using 10 ml of 0.25% bupivacaine under ultrasound guidance. Another group receives the same adductor canal block plus a BiFeS block using 20 ml of 0.25% bupivacaine, also guided by ultrasound. The control group does not receive any regional nerve block. All groups receive standard postoperative pain medicines including paracetamol and dexketoprofen. Participants will be monitored on the day of surgery for pain levels and opioid use. Researchers will measure pain scores and total morphine consumption during the first 24 hours after surgery. Ultrasound imaging confirms proper anesthetic placement during nerve blocks. The study is randomized and single-blinded, aiming to find which approach provides better pain relief while preserving muscle strength. The trial lasts from the surgery day through the initial postoperative period for recovery assessment.
