Rupture of the peroneus longus tendon is rare. We report the case of a 23-year-old man who played rugby in the top Japanese league. He found it difficult to continue playing rugby because of pain over the lateral aspect of both feet. Tenderness and swelling were localized in the lateral calcaneal region. X-ray images showed a bony eminence lateral to the calcaneus in both feet. After conservative treatment, surgery was performed. In the right foot, the peroneus brevis was found to be intact and the peroneus longus was ruptured. A bony eminence was resected and the ruptured tendon was sutured. In the left foot, there was degeneration of the peroneus brevis, and the peroneus longus was ruptured. A bony eminence was resected and the ruptured tendon was fixed to the calcaneus with anchoring suture. Repetitive friction between tendon and bony eminence had caused rupture of the peroneus longus tendon in both feet. The patient was able to resume playing rugby 4 months after surgery.
