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. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. Unstable OCDs require surgical intervention, whereas stable OCDs are generally treated conservatively. Roßbach BP, Paulus AC, Niethammer TR, et al. 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. 94, No. 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. Osteochondritis dissecans is generally diagnosed by conventional radiology. This is a well-known and validated classification system for OCD lesions. A comparison of MRI and arthroscopic finding. 11 Imaging of Osteochondritis Dissecans We define unstable OCD lesions as those with fragments that can be displaced by intraoperative probing. 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. 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 of the knee in children. This softening is caused by an interruption in the blood flow to that portion of the bone. Presentation. 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. Knee Surg Sports Traumatol Arthrosc 2016; 24:1259–1264 [Google Scholar] 1 The first description of these lesions in the ankle was provided in 1922. Juvenile versus adult osteochondritis dissecans of the knee: appropriate MR imaging criteria for instability. 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. OCD usually causes pain and swelling of the affected joint which catches and locks during movement. MRI is commonly used to assess the stability of OCD lesions of the knee .

Osteochondritis dissecans (OCD) OCD represents a chronic “overload” injury of the epiphysis. 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. It is classified into juvenile and adult forms, depending on growth plate status. Radiology. Describing OCD together with osteochondral fractures and epiphyseal ossification disturbances and considering these three conditions as one entity has caused much confusion. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion. Osteochondritis dissecans (OCD) is an acquired defect in the articular cartilage and subchondral 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.

Introduction. Magnetic Resonance Imaging After Arthroscopic Microfracture of Capitellar Osteochondritis Dissecans. Osteochondritis dissecans. The clinical utility and diagnostic performance of MRI for identification and classification of knee osteochondritis dissecans. Background Several magnetic resonance imaging (MRI) classification systems have been developed to determine the degree of instability of juvenile osteochondritis dissecans (JOCD) lesions. The cause of this condition is unknown. [1] OCD usually causes pain and swelling of the affected joint which catches and locks during movement. 94, No. Physical examination typically reveals an effusion, tenderness, and a crackling sound with joint movement. 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”). MRI classification of juvenile osteochondritis dissecans lesions Hefti F, Beguiristain J, Krauspe R, et al. 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. Complaining of pain and clicking in right knee. 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. 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: a multicenter study of the European Pediatric Orthopedic Society. Abstract. Treatment can be conservative or surgical depending on how likely the OCD is to heal on its own. J Bone Joint Surg Am 1996;78:439-56. Osteochondritis Dissecans Osteochronditis dissecans (aka “OCD”) is a condition in which the bone that supports the cartilage inside a joint undergoes softening. Case contributed by Dr Vinay Shah. 11 MRI of Pediatric Patients: Part 2, Normal Variants and Abnormalities of the Knee 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. 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. 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.
