Five cases of osteochondral lesion of the talus treated arthroscopically, were reviewed. The 3 men and 2 women patients ranged in age from 13 to 70. (mean age, 31. 8 years). The lesions were classified according to the radiographic stages described by Berndt and Harty. One ankle had stage-II lesion, three stage-III, and one stage-IV. The operations were performed under lumber anesthesia without a joint distraction system. All cases were performed debridement of osteochondral lesions and drilling. The results were assessed by Berndt crinical criteria subjectively, and the examination on X-ray and magnetic resonance imaging objectively. The average follow-up period was 7.4 months (range, 4 to 10 months).
Four patients had good results and one had a fair result. The fair case was a 70-years patient who had swelling of the ankle. All cases improved the osteogenesis on X-ray, and the cartilage like tissue covered the lesion. There were no major complications.
The arthroscopic treatment of the small osteochondral lesion of the talus can be useful in selected patients in a short period. The long-term results are still less predictable.
