What type of disease is osteochondritis dissecans?
Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion.
What is the most common site of osteochondritis dissecans?
The most common location of OCD is in the knee at the end of the femur (thighbone). (Left) The knee joint is formed where the femur meets the tibia.
What is OCD of the talus?
An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL).
What is another name for osteochondritis dissecans?
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. OCD is a type of osteochondrosis in which a lesion has formed within the cartilage layer itself, giving rise to secondary inflammation.
How is osteochondritis dissecans diagnosis?
To diagnose osteochondritis dissecans, the doctor will perform a physical examination and will assess the joint’s stability. The doctor may order tests, including the following: X-rays, which will show the bone, locate the lesion and reveal its size. A magnetic resonance imaging test (MRI), along with an ultrasound.
What is osteochondritis dissecans elbow?
Osteochondritis dissecans (OCD) is a disorder of articular cartilage and subchondral bone. In the elbow, an OCD is localized most commonly at the humeral capitellum. Teenagers engaged in sports that involve repetitive stress on the elbow are at risk.
How does osteochondritis dissecans happen?
Osteochondritis dissecans is a condition that occurs in the joints (the place where the end of one bone meets the end of another bone) when a lack of blood to the joint causes the bone inside to soften. This results in a small piece of the bone dying and separating from the larger bone.
What is osteochondritis dissecans of the knee?
Osteochondritis dissecans is a bone and cartilage condition that most often occurs in the knee. It has no known cause, but repetitive stress on the joint, low vitamin D and a genetic predisposition are often linked to this condition.
Is osteochondritis dissecans bilateral?

What is osteochondritis dissecans of the talus?
A Patient’s Guide to Osteochondritis Dissecans of the Talus. Introduction. Osteochondritis dissecans (OCD) is a problem that causes pain and stiffness of the ankle joint. It can occur in all age groups. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface.
What is osteochondritis dissecans (OCD) of the ankle?
Osteochondritis dissecans (OCD) of the ankle is the end result of the aseptic separation of an osteochondral fragment of the talar dome with the gradual fragmentation of the articular surface. See the main osteochondritis dissecans article for a general discussion on this condition, which mostly affects the knees. Article:
Osteochondritis dissecans (OCD) of the knee is a relatively common cause of pain and functional limitation among children and young adults. It is an acquired pathological condition in which the subchondral bone becomes avascular, thus destabilizing the chondral coverage.
What is the pathophysiology of OCD of the talus?
Although OCD of the talus is, by definition, detachment of an osteochondral fragment of the talar dome occurring in a growing patient, symptomatic OCD is more typically observed in adults.
