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. Osteochondral fracture occurred at the patella in 35 patients (76%), the lateral femoral condyle in 11 patients (24%), and at both locations in 3 patients (6.5%). An osteochondral fracture is caused by tearing of the articular cartilage. The large osteochondral defect was eventually managed in a staged manner with bone grafting and osteochondral autograft transfer. https://radiopaedia.org/articles/osteochondritis-dissecans-of-the-knee ... Isolated chondral fractures of the knee. 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. An osteochondral fracture is a type of fracture in which the articular cartilage at the end of a joint becomes torn. Current theory for aetiology favours repetitive microtrauma with microtrabecular fractures of subchondral bone, subsequent ischaemia and altered local growth. Furthermore, on standard knee X-rays these injuries may not be seen and thus not properly be treated. In 21 patients (44%), MRI confirmed osteochondral injury despite the plain radiograph interpretation as negative for fracture. Osteochondral injuries, if not treated adequately, often lead to severe osteoarthritis of the affected joint. The accuracy of magnetic resonance imaging scanning and its influence on management decisions in knee surgery. The fracture healed after 3 months and the knee was stable. Osteochondraldefect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. Top Magn Reson Imaging 1998; 9:348-359. Knee osteochondral fractures in skeletally immature patients: French multicenter study Better knowledge of this fracture and attentive reading of the radiographic images of a knee with hemarthrosis should result in more frequent diagnosis of this condition and adapted treatment. We describe the clinical and radiographic features of 11 athletes found to have femoral head lesions similar in MR imaging appearance to osteochondral lesions in other locations, such as the knee … The incidence of osteochondral fractures with ACL injuries may be as high as 80% [20, 21]. Less common are impression fractures of the retropatellar joint or the lateral trochlea. Fracture DataRelative frequencies of fractures Most frequently overlookedto the knee in adults fractures in an ED1. Osteochondral Fractures are also sometimes known as articular cartilage injuries. OCD usually causes pain during and after sports. Rubin DA, Kettering JM, Towers JD, Britton CA: MR imaging of knees having isolated and combined ligament injuries. Frequent abnormalities found on MR imaging include labral tear or injury, stress fracture, and avascular necrosis . Osteochondral fractures may occur with patellar dislocations (see Fig. 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. Examination and imaging identified a loose osteochondral fracture. There were two parts in the partial osteochondral avulsion fracture of the PCL posteromedial (PM) bundle. 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. Sometimes the t… Keywords: Knee, Cartilage, Synovitis, Pigmented villonodular Pigmented villonodular synovitis (PVNS) is a rare, benign, but potentially recurrent condition with an estimated incidence of 1.8 per million. 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 . 1 Osteochondral fractures, sometimes called ‘flakes’, occur as a completely detached or partially attached fragment. By presenting our cases we show clinical symptoms, diagnostic pathways and the therapeutic approach for osteochondral fractures of the distal femur. The abnormality is seen as as a scooped-out defect or linear fracture in the articular cartilage on arthrography; on arthroscopy the findings are similar, though the fracture may appear stellate in cases of a direct blow to the knee. 9 In the early phase, when they are best treated, osteochondral defects can only be seen on MRI (Figure 8). The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Prognosis of these lesions depends on stability, location, and size of the lesion. 2). Osteochondral fracture of the lateral femoral condyle is a rare injury of the knee joint, which mostly occurs in adolescence 1. AJR, 1998; 170:1207-1213 1A, B, C) in association with an anteromedial detachment of a bony fragment.A three-dimensional CT scan was realized to define the exact position and dimension of the fragment that was rotated at 90° in the sagittal plane with the articular surface oriented anteriorly (Fig. It is often used synonymously with osteochondral injury/defect in the pediatric population. Surgery was indicated to remove and potentially reattach the loose body. Screws and Kirschner wires both absorbable and nonabsorbable have been the common mode of fixation of these fractures. Without refixation of the osteochondral fragment, human cartilage can only repair these defects imperfectly. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): Osteochondral lesions are relatively common in children and adolescents, and the incidence is increasing. Unlike osteochondral fractures, chondral fractures exhibit no specific abnormalities on routine radiography, necessitating arthroscopy or arthrography for diagnosis. Osteochondral fracture In terms of medial patellar OCF fragment, it was classified based on the location of fracture site, patellar medial margin, inferomedial facet, and inferomedial facet involving central ridge [ 25 ]. The biological effect of continuous passive motion on the healing of … [1] Osteochondral fractures … Tibial plateau (16%)2. An Osteochondral fracture is a tear of the cartilage which covers the end of a bone, within a joint. 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. The most common sites are the posteromedial (53%) ( Fig. The use of fresh osteochondral allograft transplantation for tibial plateau lesions has been well documented. Patella (40%) 1. 1 ) and anterolateral (46%) talar dome ( 1 ). 2, Fig. It is also known as Osteochondritis Dissecans and is common in the knee joint, especially in association with other injuries such as ACL tears. The biomechanical strength of immature osteochondral junction was lower than that of mature osteochondral junction. 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 . 6-12) or anterior cruciate ligament (ACL) repairs. X-rays of the knee joint are requested frequently, particularly at the Emergency Assistance department. X-ray evaluations presented a posteromedial tibial plateau fracture with a disruption of a bone portion (Fig. Many of these lesions are first diagnosed by plain film. Less frequently patellar fractures may follow total knee replacement (0.68%) (see Fig. 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. Introduction. A 16-year-old male presented after a twisting injury of the knee. The only difference is that with an osteochondral fracture, there may also be a bone fracture involved. In the late phase, which is more common with presentations in young adults, they can dislodge from the bone, leaving a defect in the articular surface … Introduction. 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). Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone.
