Ultrasound-guided corticosteroid injection for proximal plantaris tendinopathy: A case report

Abstract

Minimal literature is available on the diagnosis and treatment of proximal plantaris tendinopathy. Calf pain is a common complaint in runners, ranging from myofascial pain to acute strains. Rarely, the plantaris tendon can be involved in mid-calf pain. This case highlights a 23-year-old female elite runner with a case of symptomatic proximal plantaris tendinopathy. Insidious mid-calf pain and/or tightness with tenderness to palpation was noted, and ultrasonographic examination provided an accurate diagnosis. An ultrasound-guided corticosteroid injection was performed, providing complete pain relief without recurrence, even 1 year after the initial injection. The patient was able to return to full activity. Successful treatment of this rare condition with ultrasound-guided corticosteroid injection should be considered once a proper diagnosis is made.
