Arthroscopically assisted osteochondral autogenous transplantation for osteochondral lesion of the talus using a transmalleolar approach

Osteochondral autogenous transplantation for osteochondral lesions of the talar dome is usually performed through a miniarthrotomy approach, and a medial malleolus osteotomy approach is selected if the lesion is located posteromedially. Recently, we used a transmalleolar approach without osteotomy of the medial malleolus to perform osteochondral autogenous transplantation for a lesion located in the posteromedial portion of the talar dome. We report on this technique and discuss its advantages, disadvantages, and indications.
