Long-term results of periosteal transplantation in osteochondritis dissecans of the knee

Between 1986 and 1991, a total of 18 patients (11 men and 7 women) with ost eochondritis dissecans of the knee were treated with periosteal transplanta tion. Median patient age was 19 years (range: 16-45 years). Eight patients were reoperated up to 8 years postoperatively, due to reduced range of moti on, synovitis, or formation of an exostosis in the transplanted area. Of 14 patients who were available for follow-up after 8 years (range: 5-10), 2 w ere completely pain free. Six patients had reduced range of motion, knee in stability, or quadriceps muscle atrophy. The number of reoperations and the presence of continued knee pain in most patients does not justify the exte nsive procedure of periosteal transplantation.
