[Osteochondrosis dissecans tali and sports]

26 out of 38 patients with Osteochondrosis dissecans of the talus and treated surgically were examined in a follow-up. The mean time of this postoperative follow-up after surgery was nearly 56 months. Anamnestic answers show that sport activities besides a sprained ankle joint are two of the most common factors leading to this disease. All patients without sport activities had suffered from a sprained ankle with or without ligamentous ruptur. Most of the disciplines were activities with a strong load for the ankle joints. Besides this no other etiological reason could be found in such a frequency. After surgical treatment 14 of the 22 sportsmen regained their full sport abilities, 7 of them could perform only a limited activity in sports.
