In osteochondritis dissecans, fragments of cartilage or bone become loose within a joint, leading to pain and inflammation.These fragments are sometimes referred to as joint mice. Sometimes the t… Many of these lesions are first diagnosed by plain film. For small-sized defects with intact cartilage, our treatment of choice is Retrograde Drilling of the lesion and filling it with a special bone cement. provides fine detail of lesions for pre-operative planning; MRI. This injury is more common in adolescents and young adults and typically occurs at the knee, ankle or elbow. Patients who have osteochodral lesions typically will have pain in the involved joint. Osteochondral Fractures are also sometimes known as articular cartilage injuries. persistent pain following injury, ankle sprains that do not heal with time ; findings. These symptoms could include localized ankle pain, as well as discomfort on either the inside (medial talar OLT) or outside (anterolateral talar OLT) of the ankle. The most common symptoms associated with OLTs, including pain, swelling, and stiffness, are quite nonspecific. Symptoms of Osteochondral Lesion of Talus (OLT) This condition usually is asymptomatic and is diagnosed only on MRI, which may be done for a … They can also occur from chronic, repetitive micro trauma. Many osteochondral lesions can be diagnosed by plain radiography; however, radiographs can be normal in the presence of an osteochondral lesion. The diagnosis of cartilage damage (osteochondral lesion, also known as talar dome) is often done with x-rays and/or an MRI. Additional … Treatment depends upon the size of the osteochondral defect and the condition of the overlying cartilage. They might flare up after physical activity , like climbing stairs or playing sports. An osteochondral lesion is an injury or small fracture of the cartilage surface of the talus. Symptoms of osteochondritis dissecans are a direct result of the irregularity of the cartilage within the affected joint. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. cartilage injury with associated subchondral fracture but without detachment This allows us to treat the bone defect … It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondral lesions of the talus are common and difficult problems to treat. Operative treatment should be reserved for patients who have mechanical symptoms following an acute osteochondral lesion of the talus or who are not satisfied with the result after 3 to 6 months of nonoperative treatment. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. Generally pain is the main symptom, on weight bearing and sometimes when resting as well. 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. Osteochondral lesions are relatively common in children and adolescents, and the incidence is increasing. Pain and swelling are the most common symptoms of osteochondritis dissecans. Alternatively, unstable OCD lesions may similarly present with pain, swelling, and mechanical symptoms. Osteochondritis dissecans usually affects the knee at the end of the thighbone (femur), ankle and elbow. A major symptom of this condition is severe knee pain. When a patient presents with pain, effusion, and mechanical symptoms with normal radiographs, further diagnostic workup is needed. It is fre-quently caused by a traumatic event. The condition leaves a lesion where the bone and cartilage separate. The gold standard of operative treatment for lesions measuring <1.5 cm2 … Osteochondral injuries are … What symptoms might I have & should a defect always be treated? The subchondral cysts may develop due to the forcing of cartilaginous or synovial fluid with every step. variable edema patterns, may overestimate degree of injury; unstable lesions show fluid deep to subchondral bone; sensitivity and specificity. Osteochondral defects and loose bodies are common causes of mechanical symptoms in the ankle. The pain is usually worsened by activity. Initial x-rays are taken to check the alignment of the foot and ankle, as well as look for any bone damage. Osteochondral defects in the knee are due to lesions of the cartilage and bone. Swelling of the joint can also be a symptom. Instability, locking, or catching can be other symptoms. It usually occurs in the knee, ankle or elbow. Pain with weight bearing activities If there is damage to the articulating structures of the knee, you will know it. They may also complain of mechanical symptoms, such as clicking and popping sounds caused by a loose fragment of cartilage and/or bone associated with the OLT. predicts stability of lesion with 92% sensitivity; Treatment They can start as bone bruising that develops into an osteochondral lesion. However, if the lesion is large enough, or the overlying cartilage is displaced, talar OLTs can be quite symptomatic. “Osteo” means bone and “chondral” refers to cartilage. With an MRI, the ligament structures, tendons and cartilage of the ankle can be examined and analyzed. Damage may also be the result of a direct blow to the knee. It is also known as Osteochondritis Dissecans and is common in the knee joint, especially in association with other injuries such as ACL tears. Talar dome lesions are usually caused by an injury, such as an ankle sprain. indications. teristics will dictate the treatment required to obtain a satisfactory clinical result. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). Osteochondral lesions of the talus are a reasonably infrequent cause of long-standing ankle pain and stiffness and are often the result of a severe ankle sprain type injury. OLTs on the top outside part of the talus (Antero-lateral lesions) usually have a history of a traumatic injury … An osteochondral cyst can also be present following surgery. In most cases an Osteochondral defect does not progress and deteriorate whereas as the opposite can be said of arthritis in many cases. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. Diagram shows the classic four signs of instability in an OCD lesion: 1, high signal intensity rim at the interface between the fragment and the adjacent bone on T2-weighted MR images; 2, fluid-filled cysts beneath the lesion; 3, a high-signal-intensity line extending through the articular cartilage overlying the lesion; and 4, a focal osteochondral defect filled with joint fluid. Osteochondral lesions are commonly the result of excessive force going through the knee. They typically are associated with a history of trauma; however, nontraumatic etiologies have been described. An articular cartilage injury, or chondral injury, may occur as a result of a pivot or twist on a bent knee, similar to the motion that can cause a meniscus tear. Injuries can range from a fine crack of the joint surface all the way though to a piece of the bone breaking away. They can also occur following severe trauma to the knee such as a skiing accident where the meniscus/cartilage is damaged. Symptoms. The only difference is that with an osteochondral fracture, there may also be a bone fracture involved.
