Arthroscopy in the treatment of osteochondrosis dissecans of the talus

This study consists of six cases of osteochondrosis dissecans of the talus (ODT) treated with arthroscopy, which was able to precisely evaluate the integrity of the articular surface; this exact evaluation confirmed in turn the inaccuracy of radiographic staging and often even the most sophisticated techniques (CAT scan and/or MRI). Arthroscopy allows treatment of osteochondral lesions and consensual reactive synovitis in both advanced stages and minor lesions, with recourse to transchondral perforation. Its low morbidity and short period of rehabilitation together with the subjective and objective outcome at the follow-up (4-33 months) make arthroscopy a valid alternative to arthrotomy for treating this type of lesion.
