What are the best treatments for Osteonecrosis?

Treatment for Osteonecrosis, also known as avascular necrosis, is highly personalized and depends on the stage of bone death, the size of the lesion, and the affected joint. Current medical guidelines emphasize a combination of conservative management to reduce symptoms and surgical interventions to preserve the joint or replace it when structural collapse occurs.

What are the first-line treatments for Osteonecrosis?

In the early stages of Osteonecrosis, clinicians often focus on slowing disease progression through conservative measures. This includes protected weight-bearing (using crutches or walkers to offload the joint), physical therapy to maintain range of motion, and pain management. While medication cannot reverse Osteonecrosis, it is used to manage symptoms and improve quality of life.

What medications and surgical procedures are used?

Management of Osteonecrosis often involves a multidisciplinary approach. Common interventions include:

• Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) for pain, and bisphosphonates (e.g., alendronate) which are sometimes prescribed to prevent bone collapse.


• Core Decompression: A surgical procedure where bone is removed to reduce pressure and improve blood flow.


• Bone Grafting: Replacing necrotic bone with healthy bone tissue.


• Joint Replacement: Total hip or knee arthroplasty is often the definitive treatment for advanced Osteonecrosis involving structural collapse.

Which specialists should manage Osteonecrosis?

Because Osteonecrosis is a complex condition, a coordinated care team is essential. Patients typically benefit from a team including an orthopedic surgeon, a rheumatologist (to manage underlying inflammatory conditions), a physical therapist, and a pain management specialist. At DiseaseMaps.org, 410 people with Osteonecrosis have shared their experiences, highlighting the value of connecting with others to navigate these clinical pathways.

What are the emerging treatments for Osteonecrosis?

Research into regenerative medicine is ongoing, with clinical trials exploring the use of stem cell therapy and platelet-rich plasma (PRP) to stimulate bone regeneration in early-stage Osteonecrosis. While these therapies show promise in small studies, they are not yet considered standard of care and should be discussed with a specialist.

Next steps

• Consult an orthopedic surgeon to assess the stage of your Osteonecrosis via MRI.


• Work with a physical therapist to design a joint-protection program.
