Fairbank's changes

Fairbank's changes are a series of radiographic changes seen in the knee joint due to Osteochondritis Dissecans (OCD). These changes were first described by Arthur R. Fairbank, a British orthopedic surgeon, in 1933.

Overview

Osteochondritis Dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone beneath it, comes loose from the end of the bone. Fairbank's changes are a series of radiographic changes seen in the knee joint due to this condition. These changes include flattening of the femoral condyle, upward displacement of the tibia, and the presence of loose bodies.

Fairbank's Changes

The changes described by Fairbank include:

• Flattening of the femoral condyle: This is a change in the shape of the femoral condyle, the rounded end of the femur (thigh bone). It becomes flattened due to the loss of cartilage and bone.

• Upward displacement of the tibia: The tibia (shin bone) is displaced upwards due to the loss of cartilage and bone in the femoral condyle.

• Presence of loose bodies: Loose bodies are small pieces of bone and cartilage that have broken off and are floating in the joint. They can cause pain and interfere with joint movement.

Diagnosis

The diagnosis of Fairbank's changes is made based on the patient's symptoms, physical examination, and imaging studies. The most common imaging study used is an X-ray, which can show the characteristic changes in the knee joint. Other imaging studies, such as MRI or CT scan, may also be used to confirm the diagnosis and assess the extent of the condition.

Treatment

The treatment of Fairbank's changes depends on the severity of the condition and the patient's symptoms. Non-surgical treatments include rest, physical therapy, and pain management. Surgical treatments may be necessary in severe cases or if non-surgical treatments are not effective. These may include arthroscopy to remove loose bodies, or osteochondral grafting to replace the damaged cartilage and bone.
