Rehabilitation of plantaris tendon rupture in an elite triathlete: a case report

Calf muscle injuries are common among athletes. While rupture of the medial head of the gastrocnemius muscle is the most diagnosed entity, isolated rupture of the plantaris muscle is a rare condition with limited documentation in the literature. The plantaris assists ankle plantar flexion, and is an important contributor to proprioceptive mechanisms vital for normal athletic function of the ankle and knee. This case study reports of an elite triathlete who complained of proximal right calf pain without any specific trauma.
