Left untreated, osteochondritis dissecans can lead to the development of osteoarthritis at an early age, resulting in progressive pain and disability. Osteochondritis dissecans (OCD) is a chronic condition characterized by a limited lesion of subchondral bone necrosis, which progresses slowly toward the separation of a segment of articular cartilage and its underlying avascular subchondral bone from the surrounding cancellous bone [1, 28].This condition affects twice as many males compared with females in the age group of 10 … 1. repetitive throwing / valgus stress and gymnastics / weight bearing on upper extremity 1.1. valgus stress / compressive force on the vulnerable chondroepiphysis of the radiocapitellar joint in skeletally immature patients is supported as the etiology for OCD of the capitellum 8 2. ankle sprain/instability 2.1. Radiology. Which of the following factors is the best predictor of successful non-operative management of an osteochondritis dissecans lesion in the knee? 10 It occurs most often between the ages of 10 and 20 years and is twice as common in males as in females. When lesions are unstable or displaced, surgical intervention is necessary, typically performed arthroscopically. Contents. Regardless of etiology, osteochondritis dissecans is an idiopathic focal joint disorder affecting the subchondral bone. Ischemia usually occurs in conjunction with a history of trauma. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion.Osteochondritis dissecans occurs most often in children and adolescents. Little has been published on the epidemiology of OCD in adult patients. In other cases, it may signal a medical condition. Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. Metallic fixation screws, when OCD lesion size permits their use, show high successful healing rates of 84% to 100%. In most cases, there is a full range of movement in the joint without signs of ligamentous instability. It often affects the knee or the elbow. Osteochondritis dissecans causes irregularity and fragility of affected cartilage. Although the etiology of osteochondritis dissecans is not fully elucidated, it is believed to be multi-factorial in nature. Bilateral osteochondritis dissecans of the knee and elbow.
