Ultrasound guidance is particularly useful for percutaneous injections in the diagnosis and management of painful conditions of the ankle and foot. The injectates used include steroids and local anesthetics, such as lidocaine, mepivacaine, bupivacaine, ropivacaine, and platelet-rich plasma. Osteoarthritis is the main indication for joint injections. Joints amenable to being injected include the tibiotalar, subtalar, midtarsal, and metatarsophalangeal joints. Tendon injections mainly involve the Achilles, peroneus, extensors, and tibialis tendons, while plantar fascia injections are useful for treating plantar fasciitis and plantar fibromatosis. Forefoot injections include joint arthritis, intermetatarsal bursitis, and Morton neuroma. The standardized approaches and doses reviewed in this paper are based on the authors' experience and can lead to high success in symptomatic relief for various conditions. These injections can be curative or serve as a guide to identify the source of pain when surgery or other therapeutic options are planned.
