Knee Osteonecrosis

Knee Osteonecrosis occurs when the blood supply to the knee bone is ceased, causing it to collapse and die. The condition most commonly affects the bent portion of the femur at the interior part of the knee, i.e. medial femoral condyle. Women aged more than 60 years of age are more susceptible to Knee Osteonecrosis. If not treated in time, it can lead to the development of
Osteoarthritis.

Symptoms Of Knee Osteonecrosis

  • Pain at the inside of the knee

Diagnosis Of Knee Osteonecrosis

The condition develops through various stages which may be diagnosed accordingly:  

  • Stage 1: In the earliest stage, the symptoms are most severe. An X-ray may not be able to diagnose the condition. Imaging tests such as MRI or bone scan may be needed to determine the cause and severity of the condition.
  • Stage 2: In this stage, the rounded edge of the thigh bone starts to flatten. MRI, bone scan or a CT scan may be used for diagnosis.
  • Stage 3: An X-ray can clearly determine the condition in this stage.
  • Stage 4: This is the extreme stage where the bones begin to collapse. It can also be detected through an X-ray.  

Treatment For Knee Osteonecrosis

Non-Surgical Treatment

  • Medication: Anti-inflammatory medicines may be prescribed by the knee surgeon to provide relief from pain.
  • Brace: The doctor may advise the patient to wear a knee brace to relieve stress from the joint.
  • Exercises: Some specific exercises may be recommended by the doctor to strengthen and increase flexibility of the thigh muscles.
  • Rest: Taking proper rest may help to ease the symptoms associated with the condition.  Avoiding vigorous activities such as running, jumping, etc. can also aid in fast recovery.
  • Protected Weight bearing: Canes, crutches or a walker may be used to provide support to the knee and reduce pain.    

Surgical Treatment

Surgery may be required if a large part of the bone is affected. The knee surgeon may recommend any of the following procedures:

  • Debridement: This involves arthroscopic cleansing of the joint and repairing the meniscal tears.
  • Drilling: In this procedure, drilling is done to reduce pressure on the bone surface.
  • Total knee replacement: It may be beneficial for patients going through Stage 4 Osteonecrosis. The procedure aims at replacing or regenerating the bones and cartilage.
