Comparative Study Between Adductor Canal Block With IPACK (Infiltration Between the Popliteal Artery and Capsule of the Knee) Versus Genicular Nerves Block With IPACK for Post-operative Analgesia in Knee Arthroscopy

Effective perioperative pain treatment has been documented to facilitate accelerated rehabilitation and recuperation, hence providing improved functional outcomes among individuals following knee surgeries. As a result, there has been a need to create multimodal analgesic regimens that include the usage of both regional anesthetic and systemic analgesics (Society, 2012).

Management of pain for knee surgery has been challenging, where various methods like epidural, peripheral nerve block (PNB), Local Infiltration Analgesia (LIA), intravenous (IV) analgesics like opioids, non-steroidal anti-inflammatory drugs (NSAIDs) and intra-articular (IA) injections, have been used (Tian et al., 2020).

In knee surgeries, the most difficult factor to control is pain, but early movement following surgery can be facilitated by motor-sparing regional anesthetic blocks and ultrasound-guided nerve blocks (Leung et al., 2018).

Perioperative multimodal analgesic strategies, consisting of "motor-sparing" regional anesthetic techniques combined with systemic nonopioid medications that target various pain pathways, have been developed to mitigate this risk; they confer improved pain scores and patient satisfaction, reduced opioid consumption and opiate-related adverse effects, early postoperative ambulation, shortened hospital stay, and fewer surgical complications (Kandarian et al., 2019).

The adductor canal block (ACB) is a regional anesthesia technique used to provide analgesia to the anterior and medial areas of the thigh and the knee (El-Boghdadly et al., 2021).
