A new method of treating articular chondral defects and Osteochondritis Dissecans with autogenous osteochondral plugs is described. Following animal trials in 1991, the technique has been used by the authors in 204 patients in Hungary and 31 in the United States with good to excellent results based on clinical examination, follow-up arthroscopy, magnetic resonance imaging (MRI), and computed tomography (CT) scans. The procedure can be done open, or arthroscopically in the case of smaller lesions, with newly designed and commercially available instruments. The patients have been followed at set intervals and evaluated by use of modified Hospital for Special Surgery Score (HSS), Cincinnati (condylar and patella), Bandi (donor), and Hanover (talus) scoring systems. These studies show that patients improve during the first year and then retain their good to excellent scores. Nineteen biopsies from the treated femoral condyles at various intervals up to 2.5 years show progressive and consistent evidence of deep matrix integration at the recipient donor interface.
