[Ultrasound-guided longitudinal tenotomy for plantar fasciitis. Technical note and systematic review].

longitudinal tenotomy represents an alternative for the treatment of plantar fasciitis. It is based on the extrapolation of knowledge in the Achilles tendon territory with a supporting pathophysiological basis. It is a non-invasive technique that can be performed on an outpatient basis and that would allow the rapid incorporation of the patient to their activities. Longitudinal tenotomy would prevent the patient from undergoing major surgeries.
