AVN can become serious if it progresses to bone collapse and joint damage. Early AVN may have few or no symptoms, while advanced AVN can cause severe pain, stiffness, reduced movement and difficulty walking. Treatment depends on the stage and may range from activity modification and other non-surgical measures to core decompression or joint replacement in advanced cases.

What Happens If AVN Gets Worse?

AVN generally progresses through changes in the affected bone. The exact speed varies from person to person.

1. Early AVN May Have Few Symptoms

In the beginning, some people have no noticeable symptoms. Others may develop mild pain, particularly when putting weight on the affected joint.

This is one reason AVN can sometimes remain unnoticed until the disease has progressed.

2. Pain Becomes More Frequent

As the affected bone becomes weaker, pain may become more noticeable during activities such as walking or standing.

For hip AVN, pain is commonly felt around the groin and may also occur around the buttock or thigh.

3. Pain May Occur Even at Rest

With progression, pain that initially occurs mainly during weight-bearing activities may eventually occur even when resting.

4. Bone Can Begin to Collapse

This is one of the most important complications of advanced AVN.

When the weakened bone can no longer withstand normal forces, the affected portion may fracture or collapse. In the hip, collapse of the femoral head can significantly affect the shape and function of the joint.

5. Joint Movement Becomes Limited

As bone and joint damage increases, stiffness and reduced range of motion can develop.

Patients may find it increasingly difficult to:

  • Walk comfortably
  • Climb stairs
  • Sit or stand for long periods
  • Bend the affected joint
  • Perform everyday activities

 

6. Arthritis Can Develop

Once AVN causes collapse or significant damage to a joint, secondary osteoarthritis can develop. This can further increase pain and reduce joint function.

Is AVN Always Dangerous?

No. The severity of AVN varies considerably.

A small area of osteonecrosis that does not involve a major weight-bearing portion of the bone may cause few problems and may sometimes remain stable or heal. However, larger lesions or lesions in important weight-bearing areas have a greater potential to progress.

The prognosis depends on factors such as:

  • Stage of AVN
  • Size of the affected area
  • Location of the lesion
  • Whether bone collapse has occurred
  • Which joint is affected
  • The underlying cause
  • The patient's age and overall health

 

Can AVN Get Worse Without Treatment?

Yes. AVN can progress, although the rate of progression is different for each person.

NIAMS notes that without treatment, most people with osteonecrosis develop severe pain and limited joint movement within two years, although the course can vary considerably.

This does not mean every patient will reach advanced disease within exactly two years. It means that untreated osteonecrosis carries a significant risk of progression.

What Are the Signs That AVN Is Getting Worse?

Watch for changes such as:

  • Increasing hip or joint pain
  • Pain becoming more frequent
  • Pain occurring at rest
  • Increasing difficulty walking
  • Developing a limp
  • Reduced joint movement
  • Increasing stiffness
  • Difficulty climbing stairs
  • Difficulty performing normal daily activities

A sudden increase in pain can occur when the affected bone collapses.

Why Is Early AVN Easier to Treat?

Early diagnosis matters because the bone may not have collapsed yet.

When AVN is diagnosed early, doctors may have more opportunities to consider joint-preserving treatments. Once significant collapse has occurred, preserving the natural joint becomes more difficult and joint replacement may be required.

How Is AVN Diagnosed?

X-Ray

X-rays are commonly used to evaluate the bone and monitor later-stage changes. However, early AVN may not be visible on an X-ray.

MRI

MRI is particularly important for early AVN. It can detect osteonecrosis before changes become visible on an X-ray and can help determine the extent of bone damage.

CT Scan

CT can provide detailed information about structural bone damage and may be useful in selected cases.

AVN Treatment by Stage

Treatment is not the same for every patient. Doctors consider the patient's age, stage of disease, affected bone and amount of damage when choosing treatment.

Early-Stage AVN

Depending on the individual case, treatment may include:

  • Activity modification
  • Reduced weight-bearing
  • Crutches or other walking support
  • Pain management
  • Physiotherapy
  • Treatment of the underlying cause
  • Joint-preserving surgery when appropriate

Non-surgical treatment may help control symptoms, but it generally does not cure osteonecrosis or reliably stop its progression.

Core Decompression

Core decompression is a joint-preserving surgical procedure commonly considered for selected patients with earlier-stage AVN.

The procedure involves creating channels in the affected bone to reduce pressure and encourage healing. It is generally more useful before substantial bone collapse has occurred.

Advanced AVN

When the affected bone has collapsed and the joint has developed significant damage, joint replacement may be required to relieve pain and restore function.

For advanced hip AVN, this may involve Total Hip Replacement.

Can AVN Be Cured Without Surgery?

Sometimes early, small lesions may remain stable or heal, but there is no guarantee.

Non-surgical treatments are primarily used to manage symptoms and protect the affected joint. They generally do not reverse established osteonecrosis or reliably prevent progression.

Therefore, whether surgery is necessary depends on the stage, size, location and progression of AVN, rather than the diagnosis alone.

Does Every AVN Patient Need Hip Replacement?

No.

Hip replacement is generally considered when AVN has progressed to significant bone collapse and joint damage, particularly when pain and loss of function are substantial.

Patients diagnosed before collapse may be candidates for joint-preserving procedures such as core decompression, depending on their individual condition.

Can AVN Affect Both Hips?

Yes. AVN can affect more than one joint, and both hips may be involved.

For this reason, when AVN is diagnosed in one hip, the orthopedic specialist may assess the other hip depending on the patient's symptoms, risk factors and clinical situation.

When Should You See an Orthopedic Doctor?

You should seek an orthopedic evaluation if you have:

  • Persistent unexplained hip or joint pain
  • Pain while walking or standing
  • Increasing difficulty walking
  • Reduced hip or joint movement
  • A history of long-term corticosteroid use
  • Previous fracture or joint dislocation
  • A known diagnosis of AVN
  • Increasing pain despite rest or treatment

Early diagnosis can improve the opportunity for appropriate treatment before significant bone collapse occurs.

Expert Opinion

According to Dr. Yugal Karkhur, a Best Orthopedic Doctor in Gurgaon, AVN should not be ignored simply because the pain is mild in the beginning. The important question after an AVN diagnosis is not only whether the condition is serious, but what stage it is in and whether the bone has collapsed.

Early-stage AVN may offer an opportunity for joint-preserving treatment, while advanced disease with collapse and joint damage may require joint replacement. Therefore, timely imaging, accurate staging and an individualized treatment plan are important.

Conclusion

AVN can be a serious condition because progressive loss of blood supply can weaken the bone, eventually causing bone collapse, severe pain, restricted movement and secondary arthritis.

However, AVN does not automatically mean that the joint will need to be replaced. The outcome depends greatly on when the disease is diagnosed, how much bone is affected and whether collapse has already occurred. MRI can help detect AVN early, when joint-preserving treatment may still be possible.

FAQs

Is AVN a serious disease?

Yes, AVN can become serious if it progresses to bone collapse and joint damage. However, the severity varies depending on the stage, location and size of the affected area.

What happens if AVN gets worse?

As AVN progresses, pain can increase, the bone may collapse, joint movement can become restricted and secondary arthritis may develop.

Can AVN cause permanent damage?

Yes. If the affected bone collapses and the joint becomes damaged, the resulting structural changes can be permanent and may eventually require joint replacement.

Can early AVN be treated without joint replacement?

Yes. Selected patients with early-stage AVN may be candidates for joint-preserving approaches such as core decompression. Treatment depends on the individual case.

How quickly does AVN progress?

There is no single timeline. Progression varies from person to person and depends on factors such as the affected area, lesion size and underlying cause.

Is AVN dangerous if there is no pain?

Not necessarily, but absence of pain does not rule out AVN progression. Early osteonecrosis can have few or no symptoms, which is why appropriate imaging and follow-up are important when AVN is suspected or already diagnosed.
