Osteonecrosis of the Knee

The bones require constant blood supply to remain healthy and strong. When blood supply is restricted, it can cause deterioration of the bone. Osteonecrosis of the knee occurs when blood supply is restricted to the end of the femur (thigh) or tibia (shin) bones, which can lead to deterioration of the knee joint, or osteoarthritis. Jonathan Glashow, MD, Orthopedic Surgery & Sports Medicine offers treatment for osteonecrosis of the knee to restore bone and joint health at our clinic in UES New York City.

Causes and Symptoms of Knee Osteonecrosis

The cause of knee osteonecrosis is not always known. Some risk factors that can restrict blood supply to the bones in the knee joint can include long-term steroid use, obesity, knee injuries, organ transplants, excessive alcohol use and certain medical conditions. The progression of the disease can occur over several months. Symptoms can include:

  • Swelling of the front and inside of the knee
  • Tenderness to touch
  • Pain when putting weight on the knee
  • Pain when bending
  • Limited range of motion

Osteonecrosis of the knee is more common in women, especially those over 60. Without treatment, the end of the femur or tibia, with the attached cartilage, can collapse. Osteonecrosis can lead to severe osteoarthritis and joint dysfunction, causing pain and limiting mobility.

Early detection can prevent bone and cartilage deterioration with treatment. If osteonecrosis has progressed past the stage of conservative treatment, surgery may be necessary to restore blood flow and stability to the bone and knee joint.

If you have been diagnosed with osteonecrosis or are experiencing symptoms, contact our clinic on NYC’s Upper East Side to discuss treatment.
