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: Invasive pneumococcal disease predominantly affects younger children, elderly, and immunocompromised patients. Pneumococcal meningitis is a particularly important form of presentation, considering its high rate of morbimortality. We present the case of a previously healthy 12-year-old adolescent male who was hospitalized due to suspicion of osteoarticular infection in his left foot. A few hours later, he developed meningeal signs, exhibiting slight pleocytosis and Streptococcus pneumoniae isolates in both cerebrospinal fluid and blood. Imaging studies were inconclusive regarding the nature of the foot disorder. We considered the hypothesis of osteomyelitis of the navicular bone as the most likely, for which he completed six weeks of antibiotic therapy. There was a favorable clinical evolution, along with complete absence of osteoarticular or neurological sequelae. The relevance of this clinical case resides in the unusual presentation of invasive pneumococcal disease in this age group, as well as in the rare form of orthopedic involvement.

    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.

    ABSTRACT: To present the clinical management of juvenile osteochondritis dissecans (OCD) of the knee and highlight the importance of a timely diagnosis to optimize the time needed for less invasive, non-operative therapy. A 13-year-old provincial level male soccer player presenting with recurrent anterior knee pain despite ongoing manual therapy. A multidisciplinary, non-operative treatment approach was utilized to promote natural healing of the osteochondral lesion. The plan of management consisted of patient education, activity modification, manual therapy, passive modalities and rehabilitation, while being overseen by an orthopaedic surgeon. Considering the serious consequences of misdiagnosing osteochondritis dissecans, such as the potential for future joint instability and accelerated joint degeneration, a high degree of suspicion should be considered with young individuals presenting with nonspecific, recurrent knee pain. A narrative review of the literature is provided to allow practitioners to apply current best practices to appropriately manage juvenile OCD and become more cognizant of the common knee differential diagnoses in the young athletic population.
