Osteochondral lesions of the talus: a revised classification

Foot Ankle Int. 1999 Dec;20(12):789-93. doi: 10.1177/107110079902001206.


Osteochondral lesions of the talus present a numerically small but therapeutically significant problem to the foot surgeon. The diagnosis and investigation of such lesions have been greatly enhanced by modern high resolution magnetic resonance imaging capabilities, which have provided far greater detail of the pathological anatomy. We have reviewed our experience in this area and suggest a revised classification for osteochondral lesions appropriate to the detail available on magnetic resonance imaging scans. The cause of osteochondral lesions is also discussed.
