The other name that gets associated with this problem is Osteochondritis Dissecans. Osteochondritis dissecans (OCD) is a focal idiopathic alteration of subchondral bone with risk for instability and disruption of adjacent articular cartilage that may result in premature osteoarthritis. I see patients at the Orthopedic Center of Chesterfield, St. Louis Children's Hospital and the Shriner's Hospital for Children. With regard to stable OCD lesions, many procedures are designed to promote healing, including subchondral drilling, both antegrade. Significant osteoarthritis, especially if more diffuse, rather than focal, may be a contraindication to osteochondral allograft use. For larger cartilaginous or osteocartilaginous defects, marrow stimulation, osteochondral autografts, and ACI have limitations. A variety of surgical techniques can be used to address these lesions. The MRI may also reveal kissing lesions, in which there is chondral injury on opposing articular surfaces. As a result, the small piece of bone and the cartilage covering it begin to crack and loosen. Significant mechanical symptoms may not be addressed with this approach. One common abnormality I see in the elbow is something called an OCD or an Osteochondral Defect. These patients may describe the feeling of a loose body within the joint that can occasionally be palpated on the anterior aspect of the knee. For patients in whom native cartilage and bone cannot be successfully repaired, or those that have failed previous attempts at repair of native tissue, osteochondral allograft is one option to be considered. Definition and symptoms. J Am Acad Orthop Surg 2011; 19:307. Notable findings include effusion, joint line tenderness, and, in some cases, a mobile free body may be palpated. The technique precludes filling the entire defect when multiple grafts are used and fibrocartilage forms around the periphery of the grafts. Amazon workers plan Black Friday strikes and protests. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. Displaced osteochondral fragment. The older patients may not respond to less invasive surgeries such as subchondral bone drilling. In addition, osteochondral allografts produce enough graft material to resurface larger lesions. Diagnosis of osteochondritis dissecans (OCD) is generally made during the history and physical examination. The defect is stable without evidence of in situ loose body. MaioRegen Prime (tri-layer) is indicated for the treatment of single/multiple osteochondral lesions with severely compromised bone, Outerbridge Grade IV. Objective— To establish whether osteochondral autograft transfer (OAT) procedures for osteochondritis dissecans (OCD) of the canine elbow would restore articular contour, resurface osteochondral defects with hyaline cartilage, and resolve lameness in the short term. Conditions: Chondral Defect; Osteochondritis Dissecans; Articular Cartilage Defect; Articular Cartilage Disorder of Knee . The Department of Orthopaedic Surgery at Washington University School of Medicine in St. Louis has no control over third-party websites and does not review such websites. It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. AAOS Clinical Practice Guideline: diagnosis and treatment of osteochondritis dissecans. Regardless of etiology, osteochondritis dissecans is an idiopathic focal joint disorder affecting the subchondral bone.
