This video is of an Ultrasound-guided Adductor Canal Block (ACB). This block is otherwise known as a Trans-sartorial approach to the saphenous nerve. It is also described as a "low femoral" nerve block. We use this approach for surgeries of the knee where we need to limit the amount of quad weakness. The saphenous nerve provides the majority of sensory fibers to the knee with minimal motor fibers. By focusing on the saphenous nerve in this location we can provide comparable analgesia while limiting the affects on the quad muscles and preserve the majority of muscle strength.
