Progress of ultrasound-guided nerve block in foot and ankle arthroscopy

Foot and ankle arthroscopy frequently results in severe perioperative swelling and pain. The ultrasound-guided nerve block technique stands out for its ability to offer reliable and potent pain relief. This technique not only promotes early functional exercise, but also realizes enhanced recovery after surgery, which has demonstrated significant advantages in the realm of foot and ankle arthroscopy. In recent years, blocking techniques targeting different nerve planes have been reported to expand the options available for clinical use. This article primarily describes the current application of foot and ankle arthroscopy, detailing various local nerve blocks under innervation and ultrasound guidance. By doing so, this review intends to provide insights for the selection of clinical anesthesia in foot and ankle arthroscopy.
