Treatment of Insertional Peroneus Brevis Tendinopathy by Ultrasound-Guided Percutaneous Ultrasonic Needle Tenotomy: A Case Report.

Insertional peroneus brevis tendinopathy is uncommon and treatment options for recalcitrant insertional lesions are rarely described in the literature. Ultrasound-guided percutaneous ultrasonic needle tenotomy has been described for the treatment of recalcitrant tendinopathy in the elbow, knee, and plantar fascia, but has not been described for the treatment of peroneal tendinopathy. We report a case of recalcitrant insertional peroneus brevis tendinopathy successfully treated with an ultrasound-guided percutaneous ultrasonic needle tenotomy. The treatment resulted in a rapid recovery, and the patient remained asymptomatic at the 6-month follow up. No complications were observed during follow up and the minimally invasive percutaneous procedures offers clear advantage over open techniques.
