ABSTRACT Osteochondritis dissecans (OCD) is a localized process that affects the subchondral bone and can progress to the overlying articular cartilage. The cause of this lesion remains elusive. With the vague clinical symptoms and signs of OCD, imaging plays a vital role in making the diagnosis and helping with the prognosis of OCD lesions. This article reviews current imaging modalities for the assessment of OCD including conventional radiography, nuclear medicine, computed tomography (CT), CT arthrography, magnetic resonance (MR) and MR arthrography. The role of imaging in evaluating healing of the OCD and articular congruity after surgical and nonsurgical management is discussed.

    ABSTRACT: Osteochondritis dissecans (OCD) can affect both adults and children, however the imaging characteristics and significance of imaging findings can differ in the juvenile subset with open physes. Radiography and magnetic resonance imaging (MRI) are the primary modalities used to aid in diagnosis, to define a treatment plan, to monitor progress, to assess surgical intervention, and to identify postoperative complications. Newer imaging techniques under continuous development may improve the accuracy of MRI for diagnosis and staging of OCD, and eventually may help to predict the durability of tissue-engineered constructs and cartilage repair.
