Unusual Case of Atraumatic Bilateral Achilles Tendon Rupture in the Chronic Setting

Bilateral spontaneous rupture of the Achilles tendon is a rare occurrence with few case reports in the literature. Despite being one of the strongest tendons in the lower limb, it is the most common one ruptured. Majority of Achilles tendon ruptures are unilateral. We present a case of surgically treated chronic bilateral Achilles tendon rupture in a 42-year-old patient without associated risk factors. The patient presented with atraumatic, bilateral Achilles tendon ruptures that were each treated with flexor hallucis longus transfer and V-Y gastrocnemius advancement. Our surgical repair was followed by six weeks of immobilization followed by increased strengthening in range motion with physical therapy. At six months follow-up visit, the patent had returned to his baseline function.
