Treatment can be conservative or surgical depending on how likely the OCD is to heal on its own. J Bone Joint Surg Am 2012; 94:1036. Presentation. Using radio waves and a strong magnetic field, an MRI can provide detailed images of both hard and soft tissues, including the bone and cartilage. 2008 Aug. 248(2):571-8 Osteochondritis dissecans. Multiple systems for classifying osteochondritis dissecans (OCD) of the knee have been reported. Osteochondritis dissecans (OCD) OCD represents a chronic “overload” injury of the epiphysis. Magnetic resonance imaging (MRI). Background Several magnetic resonance imaging (MRI) classification systems have been developed to determine the degree of instability of juvenile osteochondritis dissecans (JOCD) lesions. The clinical utility and diagnostic performance of MRI for identification and classification of knee osteochondritis dissecans. To diagnose osteochondritis dissecans, your orthopaedic specialist may request X-rays and an MRI of the joint. To determine whether pains are osteochondritis dissecans, an MRI, CT scan or X-ray can be performed to show necrosis of subchondral bone and/or formation of loose fragments.In specific cases, if caught early enough, a harmless dye will be injected into the blood stream to show where calcium will accumulate. For determining the best treatment for osteochondritis dissecans (OCD) of the humeral capitellum, it is important to clarify whether the lesions are stable or unstable. Given the benefits of the use of MRI as a noninvasive tool to diagnose, predict lesion progression, and assess clinical outcomes of treatment, there is a pressing need for high-level, systematic, sound, and thorough studies related to the clinical utility of MRI for assessing osteochondritis dissecans of the knee. ... MRI classification of OCD according Dipaola et al (Gr.I-IV) Treatment. Discrepancy between morphological findings in juvenile osteochondritis dissecans (OCD): a comparison of magnetic resonance imaging (MRI) and arthroscopy. Magnetic Resonance Imaging After Arthroscopic Microfracture of Capitellar Osteochondritis Dissecans. Osteochondritis dissecans was originally described in 1888 as a process of loose body formation associated with articular cartilage and subchondral bone fracture in the hip and knee. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion. Complaining of pain and clicking in right knee. Osteochondritis Dissecans Osteochronditis dissecans (aka “OCD”) is a condition in which the bone that supports the cartilage inside a joint undergoes softening. Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. A comparison of MRI and arthroscopic finding. Purpose of review Juvenile osteochondritis dissecans (JOCD) knee lesions are common abnormalities in adolescents and children, and have higher rates of spontaneous healing with nonoperative management compared to adult osteochondritis dissecans (OCD) lesions. It often affects the femoral condyles (most common: posterolateral portion of medial condyle), talar dome, and humeral capitellum but can occur in all large joints. Abstract. 4. 11 MRI of Pediatric Patients: Part 2, Normal Variants and Abnormalities of the Knee Physical examination typically reveals an effusion, tenderness, and a crackling sound with joint movement.
