What is the treatment for more advanced forms of avascular necrosis?

In most cases, you'll need surgery to treat your avascular necrosis. Surgical options can include:

• Core decompression: Your surgeon drills small holes (cores) in your affected bone to improve blood flow to the affected bone. This procedure might be combined with injections or bone grafts to promote healing.
• Joint replacement: They replace your damaged joint with an artificial one. Hip replacements and knee replacements are 95% effective at relieving pain and restoring mobility in people with avascular necrosis.
