adductor canal versus fascia iliaca block

Arthroscopic knee surgery refers to a large variety of surgical interventions in the knee, and numerous analgesic regimens have been investigated in order to ¿nd the optimal combination of analgesics for these proceduresThe femoral nerve block has been the mainstay for postoperative pain treatment following knee replacement for decades. Current trends however, focus on providing analgesia with minimal motor block. Contrary to the femoral nerve block, the adductor canal block (ACB) is predominantly a sensory nerve block, preserving quadriceps muscle strength and mobilization ability.Fascia iliaca compartment block is an anterior thigh regional block of lumbar plexus, if local anesthetics injected posterior to the fascia iliaca, it diffuse in to its internal layers then to the femoral, lateral femoral cutaneous, genitofemoral, and obturator nerves which was later confirmed by radiography.The aim of the current study is to compare the effects of ultrasound guided adductor canal block versus ultrasound guided fascia iliaca compartment block for postoperative analgesia in patients undergoing arthroscopic knee surgeries.
