title: Treatment of unstable osteochondritis dissecans lesions of the knee using autogenous osteochondral grafts (mosaicplasty).
abstract: Symptomatic osteochondritis dissecans lesions with minimal fragmentation that may be replaced within their crater have classically been treated by reattachment. The choice for internal fixation is varied. This article reports on the treatment of unstable osteochondritis dissecans lesions using autogenous osteochondral plugs as a means of biological internal fixation. The appearance on magnetic resonance imaging of osteochondral plugs at 6 and 9 months after transplantation is also presented.
