Osteochondritis dissecans facts
- Osteochondritis dissecans is a joint condition whereby a variable amount of bone and its adjacent cartilage loses its blood supply.
- The cause of osteochondritis dissecans is often unknown.
- Symptoms include joint pain, stiffness, and even locking of the joint.
- Osteochondritis dissecans is best diagnosed with imaging studies.
- Arthroscopic surgery is a procedure that is frequently used as a treatment to remove the loose cartilage and bone tissue from the joint.
What is osteochondritis dissecans?
Osteochondritis dissecans is a joint condition whereby a variable amount of bone and its adjacent cartilage loses its blood supply. Osteochondritis dissecans can involve the bone and cartilage of virtually any joint. Elbows and knees are most commonly affected. Usually, only a small portion of the affected cartilage is involved. Osteochondritis dissecans most commonly affects boys between 9 and 18 years of age.
What causes osteochondritis dissecans?
The cause of osteochondritis dissecans is often unknown. Theories include mild recurrent injuries or growth disturbances.
What are symptoms of osteochondritis dissecans?
Symptoms of osteochondritis dissecans are a direct result of the irregularity of the cartilage within the affected joint. Symptoms include joint pain, stiffness, and even locking of the joint so that its range of motion is significantly limited to the point that it cannot be moved beyond a limited range. For example, when osteochondritis dissecans affects the elbow, the joint may not move beyond 90 degrees of extension instead of being able to fully extend straight to 180 degrees.
How is osteochondritis dissecans diagnosed?
Osteochondritis dissecans can be suggested clinically by observing the lack of full range of motion with "locking" of the joint at a certain angle. It is at this angle that the loosened cartilage and bone is literally being "pinched" as the joint is attempting to move. Ultimately, osteochondritis dissecans is best diagnosed with imaging studies, such as magnetic resonance imaging scan (MRI scan) or an arthrogram.
What is the treatment of osteochondritis dissecans?
There is no cure as such, but the condition can be treated by a variety of means depending on the size and location of the lesion as well as the age of the patient and the degree of symptoms. Arthroscopic surgery is a procedure that is frequently used as a treatment to remove the loose cartilage and bone tissue from the joint. It can also be used to encourage healing by drilling and fixation of lesions that are only partially detached.
Sometimes, especially in the very young (juvenile) form, osteochondritis dissecans can spontaneously correct itself.
What is the prognosis of osteochondritis dissecans?
Indicators of a worse prognosis or outcome include a large-sized lesion, a lesion on a weight-bearing area, and older age of the patient.
Can osteochondritis dissecans be prevented?
It is only possible to prevent osteochondritis dissecans by preventing trauma or injury to the affected joint.

ArthroscopyDuring arthroscopy, a tube-like viewing instrument (called an arthroscope) is used to examine the internal structure of a joint for diagnosis or treatment. Arthroscopy is useful when attempting to diagnose or treat various types of arthritis and joint injuries. This surgical procedure may often be performed in an outpatient setting.
Elbow PainElbow pain is most often the result of tendinitis, which can affect the inner or outer elbow. Treatment includes ice, rest, and medication for inflammation. Inflammation, redness, warmth, swelling, tenderness, and decreased range of motion are other symptoms associated with elbow pain. Treatment for elbow pain depends upon the nature of the patient's underlying disease or condition.
MRI ScanMRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.
Surgery QuestionsSurgery is the branch of medicine that employs operations in the treatment of disease or injury. Prior to surgery you might consider asking your surgeon questions about the operation (procedure).
Swollen Ankles and Swollen Feet
Swollen ankles and swollen feet is a symptom of an underlying disease or condition such as edema, medications, pregnancy, injuries, diseases, infections, lymphedema, or blood clots. Symptoms associated with swelling of the ankles and feet include:
- Skin that is easily indented when pressed down with a finger that slowly returns to its more puffy state when the finger pressure is removed.
- Generalized swelling of the feet or ankles.
- Indentations marks in the skin of the feet or ankles left by socks or shoes
- The skin associated with the swelling is slightly pale, and the indentation marks are slightly darker than the surrounding swollen tissue.
Treatment for swollen ankles or feet depends upon the cause, and soothing symptoms.
