Abstract
Rarely, osteochondral lesions of the talus occur without a history of trauma. Accurate
interpretation of the mechanical load distributions onto the ankle leading to potential
atraumatic cartilage damage must always be studied. The published data on the optimal
treatment of talar osteochondral lesions in skeletally immature patients are scarce,
especially when the lesions are associated with hindfoot malalignment. We describe
the case of a pediatric female with an atraumatic osteochondral lesion of the talus associated
with a talocalcaneal coalition and a valgus hindfoot, which we consider the first
case to be reported. She presented with prolonged bilateral ankle pain and catching
during gait of approximately 2 years’ duration with a restricted range of motion,
with the pain more excruciating in the right ankle. Radiographs revealed a large osteochondral
lesion located at the lateral talar dome. The patient underwent partial osteochondral
allograft transplantation, together with hindfoot realignment and coalition resection
with a fat graft interposition. At the 2-year follow-up examination, the patient was
free of pain in her right foot and ankle, with no signs of radiologic failure.
