Osteonecrosis is a pathological process which results in death of bone and bone marrow elements and can be associated with a variety of medical conditions. Involvement of the knee is believed to account for approximately 10% of all cases.

Spontaneous osteonecrosis is more common  in patients older than 60 years.
