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. Unstable OCDs require surgical intervention, whereas stable OCDs are generally treated conservatively. OCD usually causes pain and swelling of the affected joint which catches and locks during movement. J Bone Joint Surg Am 1996;78:439-56. The Clinical Utility and Diagnostic Performance of MRI for Identification and Classification of Knee Osteochondritis Dissecans The Journal of Bone and Joint Surgery-American Volume, Vol. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion. Describing OCD together with osteochondral fractures and epiphyseal ossification disturbances and considering these three conditions as one entity has caused much confusion. MRI is most useful for classification and to determine the stability of the lesion. Osteochondritis dissecans. Although both radiography and magnetic resonance imaging (MRI) are routinely used to identify and evaluate osteochondritis dissecans lesions of the knee, MRI is often the imaging modality of choice and has been recommended as a technique to follow the healing response and degree of revascularization of the lesion 6,7. Rationale and Objectives: In this retrospective case series, we utilize arthroscopy as the gold standard to determine if magnetic resonance imaging (MRI) of the knee can predict osteochondritis dissecans (OCD) lesion stability, the most important information to guide patient treatment decisions. J Bone Joint Surg Am 2012; 94:1036.

In vivo visualization using MRI T2 mapping of induced osteochondrosis and osteochondritis dissecans lesions in goats undergoing controlled exercise; Novel Arthroscopic Classification of Osteochondritis Dissecans of the Knee – A Multicenter Reliability Study We define unstable OCD lesions as those with fragments that can be displaced by intraoperative probing. Osteochondritis dissecans. 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. Osteochondritis dissecans of the knee in children. MRI is commonly used to assess the stability of OCD lesions of the knee . Abstract. These existing classification systems have some similar characteristics, such as stable lesion/intact articular cartilage and presence of a loose body. 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. Diagnosis probable Diagnosis probable . However, variations are found in the number of stages and specific lesion characteristics assessed. Background Several magnetic resonance imaging (MRI) classification systems have been developed to determine the degree of instability of juvenile osteochondritis dissecans (JOCD) lesions. Osteochondritis Dissecans (OCD) Injuries & Conditions Osteochondritis Dissecans is a condition that affects synovial joints , resulting in localised abnormalities of the articular cartilage, such that the cartilage softens and can eventually dislodge and become a floating loose body within the knee. Eur. 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. Osteochondritis dissecans: a multicenter study of the European Pediatric Orthopedic Society. Schenck RC Jr, Goodnight JM. Case contributed by Dr Vinay Shah. Osteochondritis Dissecans (OCD) A contour change sharply demarcated that involves the chondro-osseous surface and appears to be chronic in nature may be characterized as an osteochondral defect; one subset of osteochondral defect that occurs in young patients is osteochondritis dissecans, which can be graded when there is history of trauma. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. [1] OCD usually causes pain and swelling of the affected joint which catches and locks during movement. Osteochondritis Dissecans Osteochronditis dissecans (aka “OCD”) is a condition in which the bone that supports the cartilage inside a joint undergoes softening. 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. Osteochondritis dissecans (OCD) OCD represents a chronic “overload” injury of the epiphysis. This is a well-known and validated classification system for OCD lesions. Magnetic Resonance Imaging After Arthroscopic Microfracture of Capitellar Osteochondritis Dissecans. 11 MRI of Pediatric Patients: Part 2, Normal Variants and Abnormalities of the Knee 11 Imaging of Osteochondritis Dissecans Radiology. Osteochondritis dissecans (OCDs) are acquired disorders of bone in which there is fragmentation of the articular surface to varying degrees. 2008 Aug. 248(2):571-8 Treatment can be conservative or surgical depending on how likely the OCD is to heal on its own. 1. The clinical utility and diagnostic performance of MRI for identification and classification of knee osteochondritis dissecans. Am J Sports Med. ... MRI classification of OCD according Dipaola et al (Gr.I-IV) Treatment. The following keywords were used: (“Osteochondritis Dissecans” OR “Osteochondrolysis” OR “Osteochondrosis Dissecans” OR “Osteochondral Defect”) AND ((Stability OR Instability) OR (Grade OR Grading OR Graded OR stage* OR Classification*)) AND (“MRI” OR “MRI” OR “MR”). 94, No. 13 , 15 , 16 However, osteochondritis dissecans has been linked to: Repetitive trauma or stress on a joint, such as from playing sports; Genetic predisposition in some patients; Osteochondritis Dissecans Diagnosis and Treatment. Introduction. It is classified into juvenile and adult forms, depending on growth plate status. On MRI, the cartilage can be visualized most clearly, including an assessment of the lateral cartilage margin of the capitellum, which is important in determining the course of treatment. Roßbach BP, Paulus AC, Niethammer TR, et al. Physical examination typically reveals an effusion, tenderness, and a crackling sound with joint movement. CAFFEY J, MADELL SH, ROYER C, MORALES P. Ossification of the distal femoral epiphysis. Osteochondritis (osteochondrosis) dissecans (OCD) is a common condition in children, adolescents, and young adults.

Osteochondritis dissecans: History, pathophysiology and current treatment concepts. Osteochondritis dissecans (OCD) of the knee is an idiopathic, focal, subchondral-bone abnormality that can cause instability or detachment of a bone fragment and overlying articular cartilage, with subsequent progression to osteoarthritis. Osteochondritis dissecans is generally diagnosed by conventional radiology. 94, No. Abstract. Orthop J Sports Med . 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. This softening is caused by an interruption in the blood flow to that portion of the bone. A comparison of MRI and arthroscopic finding. Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. There is no verified classification of OCD of the elbow for CT images; therefore we used the classification of Clanton and DeLee 16 for osteochondritis dissecans of the knee. The cause of this condition is unknown. Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. 2012 Sep 26. .
