Diagnosis probable Diagnosis probable . Presentation. Radiol. This softening is caused by an interruption in the blood flow to that portion of the bone. 8, 103±112 (1998) Ó Springer-Verlag 1998 European Musculoskeletal radiology Radiology Review article Osteochondritis (osteochondrosis) dissecans: A review and new MRI classification K.

Kijowski R, Blankenbaker DG, Shinki K, Fine JP, Graf BK, De Smet AA. 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. 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. Osteochondritis dissecans of the knee in children. Osteochondritis dissecans (OCD) OCD represents a chronic “overload” injury of the epiphysis. 94, No. Osteochondritis dissecans.

Osteochondritis dissecans (OCDs) are acquired disorders of bone in which there is fragmentation of the articular surface to varying degrees. Osteochondritis dissecans is generally diagnosed by conventional radiology. 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. It is classified into juvenile and adult forms, depending on growth plate status. Osteochondritis dissecans: a multicenter study of the European Pediatric Orthopedic Society. OCD usually causes pain and swelling of the affected joint which catches and locks during movement. Magnetic resonance imaging (MRI). 2008 Aug. 248(2):571-8 Abstract. 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: History, pathophysiology and current treatment concepts. MRI is commonly used to assess the stability of OCD lesions of the knee . Osteochondritis dissecans (OCD) is an acquired defect in the articular cartilage and subchondral bone. Radiology. 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. Osteochondritis dissecans. Osteochondritis Dissecans Osteochronditis dissecans (aka “OCD”) is a condition in which the bone that supports the cartilage inside a joint undergoes softening. Complaining of pain and clicking in right knee. 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. To diagnose osteochondritis dissecans, your orthopaedic specialist may request X-rays and an MRI of the joint. 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. 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. Case contributed by Dr Vinay Shah. Treatment can be conservative or surgical depending on how likely the OCD is to heal on its own. MRI classification of juvenile osteochondritis dissecans lesions Hefti F, Beguiristain J, Krauspe R, et al. A comparison of MRI and arthroscopic finding. Abstract. The clinical utility and diagnostic performance of MRI for identification and classification of knee osteochondritis dissecans. Eur. ... MRI classification of OCD according Dipaola et al (Gr.I-IV) Treatment. OCD is a condition that affects the subchondral bone and potentially the overlying articular cartilage. 11 Imaging of Osteochondritis Dissecans 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. Discrepancy between morphological findings in juvenile osteochondritis dissecans (OCD): a comparison of magnetic resonance imaging (MRI) and arthroscopy. 1. Multiple systems for classifying osteochondritis dissecans (OCD) of the knee have been reported. Magnetic Resonance Imaging After Arthroscopic Microfracture of Capitellar Osteochondritis Dissecans. Osteochondritis (osteochondrosis) dissecans (OCD) is a common condition in children, adolescents, and young adults. 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. However, variations are found in the number of stages and specific lesion characteristics assessed. 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. Introduction. 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. 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. 11 MRI of Pediatric Patients: Part 2, Normal Variants and Abnormalities of the Knee 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. Orthop J Sports Med . We define unstable OCD lesions as those with fragments that can be displaced by intraoperative probing. CAFFEY J, MADELL SH, ROYER C, MORALES P. Ossification of the distal femoral epiphysis. Unstable OCDs require surgical intervention, whereas stable OCDs are generally treated conservatively. Juvenile versus adult osteochondritis dissecans of the knee: appropriate MR imaging criteria for instability. 13 , 15 , 16 Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. 2018 Sep. 6 (9):2325967118794620. MRI is most useful for classification and to determine the stability of the lesion. 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. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. 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. 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”). Physical examination typically reveals an effusion, tenderness, and a crackling sound with joint movement. Background Several magnetic resonance imaging (MRI) classification systems have been developed to determine the degree of instability of juvenile osteochondritis dissecans (JOCD) lesions. Am J Sports Med. Roßbach BP, Paulus AC, Niethammer TR, et al. 94, No. 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.
