| Summary: | Osteochondritis dissecans most commonly affects the knee, elbow, and ankle. Due to its similarity and previous confusion with other conditions such as osteochondral fractures and osteonecrosis, and the inability to investigate the development of lesions prior to clinical presentation, the exact pathogenesis remains an enigma. The true incidence and prevalence are unknown because of the varying degree of symptomatology and the plethora of diagnostic and treatment algorithms. In this article, we provide an overview of the existing diagnostic criteria, lesion classification systems, and treatment algorithms.
