Osteochondral lesions of the talus: defining the surgical approach.

It has become clear that contrary to the previously held belief that osteochondral lesions of the talus occurred anterolaterally and posteromedially, there is a much wider spread across the talus. Lesions can now be mapped by their biology and geography, and from this the ideal procedure and the ideal surgical approach can be selected. Familiarization with a range of skills, such as posterior ankle arthroscopy and malleolar osteotomies, are required to be able to perform this surgical plan.
