The adductor canal block (ACB) is an effective regional anaesthesia technique for postoperative analgesia following knee surgeries while preserving quadriceps strength, facilitating early mobilisation and rehabilitation. It targets the saphenous nerve within the adductor canal between the vastus medialis, sartorius, and adductor longus muscles. Compared to the femoral nerve block, ACB reduces motor blockade while providing equivalent analgesia. Ultrasound-guided techniques improve accuracy, with local anaesthetic injected anterolateral to the femoral artery. Common indications include total knee arthroplasty and anterior cruciate ligament reconstruction. Complications such as vascular puncture, nerve injury, and motor weakness can occur but are rare. Continuous catheter techniques provide prolonged analgesia for enhanced recovery.
