Osteochondral autograft for medial femoral condyle chondral lesions in a patient with multiple epiphyseal dysplasia: long-term result

Multiple epiphyseal dysplasia (MED) is a form of osteochondrodysplasia characterized by abnormal epiphyseal growth and assumed to be a clinical condition of extracellular matrix abnormality [1]. Osteoarthritis and chondral lesions, for example osteochondritis dissecans (OCD), are among the clinical expressions of MED [2, 3]. It is possible for osteoarthritic changes of the knee to develop easily even in young patients with MED [4]. Total knee arthroplasty (TKA) and correction osteotomy have been performed for severe deformity and destruction of the knee in MED patient [4, 5].
