Osteonecrosis of the knee is a condition where a segment of bone in the knee area dies. This segment is usually the inside part of the thigh bone, but can also be the bottom part or the outside part of the thigh bone.
The cause for osteonecrosis of the knee is unknown, but is thought to be related to prior injuries to the knee.
Women are three times as likely to develop osteonecrosis of the knee as men, and most people are over the age of 60 when it occurs. If not treated early, this condition can lead to severe osteoarthritis.

If you have these symptoms you should see your doctor.
To diagnose this condition, your physician may obtain an X-ray of your knee, a CT scan, a MRI scan, and/or a bone scan, depending on the severity of your symptoms and the amount of information gained by previous diagnostic studies.
For less severe conditions, pain medication, a brace, activity modifications, rehabilitation exercises and rest may be all you need to recover. In more severe situations, however, surgery may be indicated.
