Treatment for Osteonecrosis of the Knee

Bones are living organic tissue and require blood supply to stay strong and healthy. The large bones in the leg are the femur and tibia, meeting at the knee joint. When blood supply is restricted to the ends of the bones in the knee, the bone can deteriorate, causing knee joint pain and dysfunction. This condition is called osteonecrosis of the knee, which can lead to osteoarthritis and joint failure. At Jonathan L. Glashow, MD orthopedic surgery and sports injury center, we offer treatment for osteonecrosis of the knee in Miami, FL.

What Causes Knee Osteonecrosis?

There are risk factors that can contribute to osteonecrosis of the knee, but the cause is not always known. Anything that impacts the blood supply reaching the ends of the femur and tibia that meet in the knee joint can result in bone deterioration. Some of the risk factors include:

  • Gender – females are more prone to osteonecrosis
  • Age – those over 60 years of age are most likely to be affected
  • Weight – obesity can increase the risk of lost blood supply to the bones
  • Substance abuse – excess use of steroid, alcohol and certain drugs can increase risk
  • Injuries – damage to the bones or knee joint may contribute to osteonecrosis

Osteonecrosis of the knee can occur over a period of several months to a year, resulting in deterioration of the bones and knee joint.

Symptoms of Knee Osteonecrosis

Detecting osteonecrosis of the knee early is vital for effective treatment. Once the bones deteriorate, reversal of the disease is unlikely. Patients with osteonecrosis may experience swelling and pain in the front and inner side of the knee. Pain may increase when bending the knee or when placing weight on the knee. Range of motion may be decreased, and the knee may be tender to the touch.

Treatment for osteonecrosis of the knee may include conservative and non-surgical procedures if detected early. This can slow or stop the deterioration of the bone and cartilage. Progressed disease may require surgery to restore knee function.

If you have symptoms of osteonecrosis of the knee, do not wait to see an orthopedist for treatment. Contact us at the office of Jonathan L. Glashow, MD in Miami to schedule an appointment for knee pain diagnosis and treatment.
