Osteochondritis dissecans is a condition of the joints that involves lack of blood flow that causes the bone underneath the cartilage to die. When this happens, the bone and cartilage break loose, resulting in pain and hindered joint movement. The condition often occurs in children and adolescents and is usually caused by a joint injury or months of training in high-impact activities. While it mostly affects the knee, Osteochondritis dissecans may also occur in ankles, elbows and other joints.
Doctors rate Osteochondritis dissecans in different stages depending on the severity and size of injury. If the affected cartilage and bone stays intact, little to no symptoms may be experienced. The condition usually heals in itself for young children. In some cases, however, surgery may be necessary.
The symptoms of Osteochondritis dissecans depends on what joint is affected. The symptoms are usually triggered by various activities, such as climbing the stairs or a hill, or playing sports. Symptoms may include:
Swelling and tenderness. You may notice that there’s some tenderness around the affected area and may appear swollen, too.
Locking or popping joint. Loose fragments may get caught between the bones when moving, thus causing the joints to lock or pop.
Weakness in the joint. With this condition, the joint may feel weakened.
Decreased motion range. The affected limb may experience decreased range of motion, which makes you unable to stretch the limb completely.
If the joint pain becomes persistent, or there is swelling, see a doctor as soon as possible.
Experts still cannot point out the main cause of osteochondritis dissecans. But some theories state that it may be due to decreased flow of the blood in the area caused by repetitive trauma.
Genetics may also be a factor.
