In this article, the literature describing the origin, course, and termination of the nerves innervating the ankle joint is reviewed and discussed. The anterior aspect of the joint capsule receives innervation from articular branches from the saphenous, superficial, and deep fibular nerves; laterally from the sural and superficial fibular nerves; and medially and posteriorly from the saphenous and tibial nerves. Comprehensive mapping of the trajectory, spatial relationships, and termination of the articular branches innervating the ankle joint capsule will aid in developing new and improving existing image-guided nerve block and radiofrequency ablation protocols to treat chronic joint pain.
