A painful condition where pieces of articular cartilage become detached from the joint surface.
A condition that develops from stress fractures of the underlying cartilage of a joint, often the knee, elbow, or ankle.
A condition that develops from stress fractures of the underlying cartilage of a joint, often the knee, elbow, or ankle joint. Osteochondritis dissecans (OCD) is caused by small fragments of cartilage and bone being separated and sometimes released into the interior of a joint, often the knee joint, followed by an interruption of blood supply to the fragment. Symptoms include an aching pain that becomes worse with activity. Range of motion of the joint is usually normal. OCD is generally diagnosed with X rays. MRI (magnetic resonance imaging) is sometimes recommended when it is necessary to evaluate the size and healing potential of the OCD lesion. When OCD is diagnosed in children, it is called juvenile osteochondritis dissecans. Juvenile OCD tends to heal in about half of all cases in which the fragment is not yet free in the joint and, when healed, does not lead to arthritic changes in the knee as the child becomes an adult. When the condition does not heal independently, surgery becomes necessary to reposition or stabilize the fractured bone fragment. Standard knee surgery or arthroscopy, the use of 3 small viewing instrument to perform knee surgery, may be recommended to restore the knee joint to its original condition. In some cases, the fractured bone fragment may have to be pinned back into position.
Release of a small fragment (or fragments) of bone and cartilage into a joint, most frequently the knee, with resulting pain, swelling, and limitation of movement. If the condition persists, or relapses frequently, arthrotomy, followed by extraction of the bone fragments, may be required.
A condition affecting a joint in which a fragment of cartilage and its underlying bone become detached from the articular surface. It commonly occurs in the knee joint.
The deterioration of a bone beneath a joint surface, resulting in the detachment of bone and cartilage fragments; this can lead to joint locking. This ailment often impacts the knee and typically initiates during adolescence. Indications encompass aching sensations, occasional swelling, and discomfort in the affected joint.
If a fragment has not entirely detached from the bone, the joint might be immobilized with a plaster cast to facilitate reattachment. In instances of loose bone or cartilage fragments within the knee, they are removed through arthroscopy. Interference with the joint’s smooth surface can elevate the likelihood of developing osteoarthritis.
A joint condition marked by the partial separation of cartilage and the underlying bone from the joint surface, often leading to the presence of what are known as “loose bodies” within the joint. This condition most frequently occurs in the knee joint.
