[Long-term surgical results of osteochondrosis dissecans of the knee joint in adolescents less than 16 years of age].

The correct therapy of osteochondritis dissecans in patients under 16 years is very important to prevent the knee joint from secondary arthritis. We analysed clinical, radiological and with MRI the long term (10 years) results of a follow-up study on 36 patients under 16 years with 42 operatively treated osteochondritis dissecans of the knee joint. There were excellent and good results in 81% of the patients. After an average of 10 years there were no signs of arthritis which would necessitate any treatment.
