What is a bone infarct in the knee?
Likewise, people ask, what causes bone infarct?
The above list applies to both bone infarct and subchondral avascular necrosis. Some conditions are more likely to lead to one over the other: Sickle cell disease and Gaucher disease very commonly cause bone infarcts and less commonly cause subchondral AVN.
Secondly, what causes dead bone in knee? Avascular necrosis of the knee happens when the blood supply is cut off to the bone cells in the knee. Anything that causes pressure to build up and crowd the bone marrow can reduce the blood supply to the bone cells.
Then, how is osteonecrosis of the knee treated?
When osteonecrosis is diagnosed early, treatment may involve taking medications to relieve pain or limiting use of the affected knee. For patients with more advanced osteonecrosis, however, treatment almost always involves surgery to prevent further damage to the bone and improve function in the joint.
Can osteonecrosis be cured?
Non-surgical treatments do not cure osteonecrosis, but they may help manage the disease. Your doctor may recommend one or more non-surgical treatments, especially if the disease is in its early stages.
