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 osteochondritis dissecans of the knee were treated with periosteal transplantation. Median patient age was 19 years (range: 16-45 years). Eight patients were reoperated up to 8 years postoperatively, due to reduced range of motion, 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 were completely pain free. Six patients had reduced range of motion, knee instability, or quadriceps muscle atrophy. The number of reoperations and the presence of continued knee pain in most patients does not justify the extensive procedure of periosteal transplantation.
