  https://orthoinfo.aaos.org/en/diseases–conditions/osteochondritis-dissecans/

  Osteochondritis dissecans (OCD) is a condition that develops in joints in children and adolescents. It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. As a result, the small piece of bone and the cartilage covering it begin to crack and loosen. […] The most common joints affected by osteochondritis dissecans are the knee, ankle and elbow, although it can also occur in other joints. The condition typically affects just one joint; however, some children can develop OCD in several joints. […] In many cases of OCD in children, the affected bone and cartilage heal on their own, especially if a child is still growing. […] In grown children and young adults, OCD can have more severe effects. The OCD lesions have a greater chance of separating from the surrounding bone and cartilage and can even detach and float around inside the joint. In these cases, surgery may be necessary.

  Osteochondritis dissecans (OCD) happens when a section of bone and cartilage in one of your joints loses its blood supply. […] A healthcare provider will diagnose osteochondritis dissecans with a physical exam and imaging tests. […] Your provider will use X-rays or an MRI (magnetic resonance imaging) to take pictures of your joints. You might need genetic testing to confirm or rule out familial OCD.

• #3 Osteochondritis Dissecans: A Diagnosis Not to Miss | AAFP

  https://www.aafp.org/pubs/afp/issues/2000/0101/p151.html

  Osteochondritis dissecans is the most common cause of a loose body in the joint space in adolescent patients. Because clinical findings are often subtle, diagnosis requires a high index of suspicion. The diagnosis is made by radiographic examination, and magnetic resonance imaging has a key role in determining the stability of the lesion. […] Clinical findings may be subtle, so clinicians should have a low threshold of suspicion for obtaining radiographs. Early diagnosis and appropriate management may prevent long-term sequelae. […] OCD is a radiologic diagnosis. If OCD of the knee is suspected, anteroposterior, lateral and tunnel-view (knee in flexion) radiographs are indicated. Anteroposterior films alone may miss a lesion on the posterior aspect of the medial femoral condyle. […] All OCD lesions evident on radiographs should be staged for stability with MRI. MRI has a 97 percent sensitivity for detecting unstable lesions. […] If the MRI demonstrates an unstable lesion (stage III or IV), arthroscopy should be employed to determine the integrity of the cartilaginous surface.

  After discussing your child’s symptoms and medical history, the doctor will perform a physical examination of the affected joint. […] Other tests which may help the doctor confirm a diagnosis include: […] X-rays provide detailed pictures of dense structures, like bone. An X-ray of the affected joint is essential for an initial OCD diagnosis, and to evaluate the size and location of the OCD lesion. […] MRI and ultrasound can create better images of soft tissues, like cartilage. An MRI can help the doctor evaluate how much the cartilage around the bone is affected. […] Your child’s doctor may still follow the OCD lesion with X-rays at certain time points to check for healing. […] Your child’s doctor may recommend surgery if: […] Nonsurgical treatment fails to relieve pain and swelling

• #6 Osteochondritis dissecans – Wikipedia

  https://en.wikipedia.org/wiki/Osteochondritis_dissecans

  Osteochondritis dissecans (OCD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. […] The disease can be confirmed by X-rays, computed tomography (CT) or magnetic resonance imaging (MRI) scans. […] To diagnose osteochondritis dissecans, an X-ray, CT scan or MRI scan can be performed to show necrosis of subchondral bone, formation of loose fragments, or both. […] Physical examination often begins with examination of the patient’s gait. […] The Wilson test is also useful in locating OCD lesions of the femoral condyle. […] X-rays show lucency of the ossification on the anterior aspect of the knee in juvenile patients. […] Magnetic resonance imaging (MRI) is useful for staging OCD lesions, evaluating the integrity of the joint surface, and distinguishing normal variants of bone formation from OCD by showing bone and cartilage edema in the area of the irregularity. […] Computed tomography (CT) scans and Technetium-99m bone scans are also sometimes used to monitor the progress of treatment.

  https://www.medicalnewstoday.com/articles/osteochondritis-dissecans-stages

  Osteochondritis dissecans is a medical condition that affects the joints. […] Diagnosis of osteochondritis dissecans depends on the results of imaging tests. However, a clinical assessment in a doctors office is also essential. […] The doctor typically examines the joint to check for swelling, tenderness, or loose cartilage fragments. […] They will then order imaging tests. X-rays help identify or localize the lesions, but they cannot determine their stability. An MRI can produce an accurate image of the lesions and help with clinical decision-making concerning lesion stability. […] Therefore, MRI scans are typically effective for all stages of osteochondritis dissecans, while X-rays could be helpful in more advanced stages. […] A doctor may also use arthroscopy. This involves visualizing the interior of a joint using a specialized narrow tube with an attached camera. It may reveal details beneficial in making a diagnosis. […] It consists of four stages, and stage IV is the unstable stage of the disease. Diagnosis requires radio imaging modalities such as a plain X-ray and MRI of the joint.
