The authors report two rare cases of children with osteochondral lesions located on the central portion of the talar dome. They were a 9-year-old boy and an 8-year-old boy. They complained of ankle pain after ankle sprain. Physical examination showed tenderness at the central talar dome and restricted of range-of-motion of their affected ankles. Plain X-ray and magnetic resonance images showed that the osteochondral lesions located on the central talar dome. Two months of conservative treatment with weight limitation and antiphlogistics gave no relief. We performed arthroscopic retrograde drilling, Kirschner wire was inserted using a drill guide by drilling from the lateral edge of the Achilles tendon to their lesions. Nine months after operation both patients were free of symptoms.
