Magnetic resonance imaging (MRI) is necessary to fully characterize the size, shape, and location of the osteochondral fracture fragment and to help the surgeon predict suitability for fixation (Figs 1 and 2). There is often an associated bone bruise of the femoral condyle. Less common are impression fractures of the retropatellar joint or the lateral trochlea. Surgery was indicated to remove and potentially reattach the loose body. Fractures of the fibular neck and head may be associated with damage to the common peroneal nerve and collateral ligament complex and may be part of a pronation lateral rotation ankle injury. The fracture healed after 3 months and the knee was stable. Furthermore, on standard knee X-rays these injuries may not be seen and thus not properly be treated. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Osteochondral Injury, Knee Rubin DA, Kettering JM, Towers JD, Britton CA: MR imaging of knees having isolated and combined ligament injuries. Osteochondral fracture of the patella is a common concomitant injury of the knee, especially in lateral patellar instability, and the importance of early stable fixation with minimal complication and early mobilization should be emphasized. Whereas osteochondritis is the leading cause of cartilage loss of the knee's medial condyle in children, osteochondral fractures (OCFs) preferentially involve the lateral condyle (as well as the femoropatellar compartment) , .The rare cases of osteochondritis of the lateral condyle should suggest a search for malformative discoid meniscus . The knee is a synovial joint formed by the femoral condyles articulating with the tibial condyles (figs 1 and 2). Screws and Kirschner wires both absorbable and nonabsorbable have been the common mode of fixation of these fractures. 1 Osteochondral fractures, sometimes called ‘flakes’, occur as a completely detached or partially attached fragment. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. In adolescence, the cartilage‐bone interface is the weakest transitional area in the knee joint, and there is no obvious boundary between calcified and uncalcified cartilage 2. Less frequently patellar fractures may follow total knee replacement (0.68%) (see Fig. The biomechanical strength of immature osteochondral junction was lower than that of mature osteochondral junction. The accuracy of magnetic resonance imaging scanning and its influence on management decisions in knee surgery. The biological effect of continuous passive motion on the healing of … It is also known as Osteochondritis Dissecans and is common in the knee joint, especially in association with other injuries such as ACL tears. 6-11). [1] Osteochondral fractures … An osteochondral fracture is caused by tearing of the articular cartilage. There were two parts in the partial osteochondral avulsion fracture of the PCL posteromedial (PM) bundle. The articular cartilage is responsible for covering the endpoint of bone in a joint and is susceptible for tearing in case of a direct or forceful impact or a twisting movement. Depending on the severity of the fracture, there are a number of treatment options ranging from fairly conservative treatments to surgery. This study determined that chondral injuries were more frequently detected compared with meniscal and ACL injuries, and patterns varied depending on stage of physeal closure. In 21 patients (44%), MRI confirmed osteochondral injury despite the plain radiograph interpretation as negative for fracture. The most common sites are the posteromedial (53%) ( Fig. It is important … Please note that OCD is a commonly used abbreviation for both osteochondral defect and osteochondritis dissecans, two closely related conditions. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): An osteochondral fracture is a type of fracture in which the articular cartilage at the end of a joint becomes torn. Patellar dislocation is a common sports injury of the knee in adolescents ().During the dislocation and reduction process, the medial facet of the patella shears with the lateral femoral condyle, which often results in patellar or lateral femoral condylar osteochondral fractures (OCFs) (2,3).The incidence of OCF following a patellar dislocation varies from 5% to 54% (4,5). Osteochondraldefect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. Chondral and osteochondral injuries were the most common lesions discovered in children undergoing MRI for evaluation of internal derangement of the knee in one study . A 16-year-old male presented after a twisting injury of the knee. Sometimes the t… Prognosis of these lesions depends on stability, location, and size of the lesion. Osteochondral Fractures are also sometimes known as articular cartilage injuries. X-ray evaluations presented a posteromedial tibial plateau fracture with a disruption of a bone portion (Fig. Patella (40%) 1. The loose body was localized arthroscopically, and an … Osteochondral fractures may occur with patellar dislocations (see Fig. Without refixation of the osteochondral fragment, human cartilage can only repair these defects imperfectly. The incidence of osteochondral fractures with ACL injuries may be as high as 80% [20, 21]. These fractures are most commonly seen in the knee and ankle joints, as these joints take a lot of strain and bear a lot of weight, which can make them vulnerable to damage. Introduction. Prognosis of these lesions depends on stability, location, and size of the lesion.Imaging has an essential role in the diagnosis, staging, and management of osteochondral lesions. Current theory for aetiology favours repetitive microtrauma with microtrabecular fractures of subchondral bone, subsequent ischaemia and altered local growth.
