A compression pinning system for osteochondritis dissecans of the knee

A new pinning technique for fixation of osteochondritis dissecans of the knee is presented. The system consists of hooked wires, anchoring screws, and bolts, which provide compression to the osteochondral fragments and prevent pin migration. In 10 patients followed for 4 (3-5) years, all the knees had normal, painless function, with complete healing of all but one of the fragments: the exception was a small chondral fragment, which was removed arthroscopically.
