Adductor Canal Block With IPACK Versus 4-in-1 Block for Postoperative Analgesia in Knee Surgery

This randomized interventional study compares the analgesic efficacy of Adductor Canal Block combined with Infiltration of the Posterior Capsule of the Knee (IPCAK) versus the 4-in-1 block technique in patients undergoing knee surgery. Twenty-four patients were randomly allocated into two equal groups. The primary objective is to compare postoperative pain scores and analgesic requirements. Secondary outcomes include time to first rescue analgesia, total analgesic consumption, motor function preservation, and block-related complications.
