What are the symptoms of avascular necrosis?

Early AVN may have no symptoms at all. As it progresses, groin pain and hip stiffness develop — initially only with activity, then progressively at rest. Pain may also radiate to the knee. A limp develops as the condition worsens. Rapid-onset hip pain in a patient with steroid use or alcohol history should always raise suspicion of AVN.

Where can I get AVN treatment in Hyderabad?

Pure Ortho Hospitals in Sainikpuri, Hyderabad has orthopaedic specialists experienced in diagnosing and staging AVN with MRI, and managing it appropriately across all stages — from early conservative measures and core decompression to hip replacement when needed.

What medications help in avascular necrosis?

Bisphosphonates (which reduce bone resorption) and lipid-lowering agents have been studied in AVN management, particularly steroid-related cases. Their role is supportive and limited — they do not reverse established AVN. They are most relevant in early stages alongside activity modification. A specialist assessment determines whether they are appropriate for your case.

Can AVN be completely cured?

True cure — complete reversal of the necrosis and full restoration of normal bone — is only reliably achievable in the very earliest pre-collapse stages, and even then is not guaranteed. The realistic goals of treatment are halting progression, preserving joint function for as long as possible, and eventually replacing the joint when needed to restore pain-free mobility.

Is AVN related to COVID or steroid treatment?

Yes. A significant number of post-COVID AVN cases have been documented in India and globally, primarily in patients who received high-dose corticosteroids during COVID-19 treatment. Patients who received systemic steroids during COVID and have subsequently developed hip pain should seek evaluation for AVN specifically — as early diagnosis allows for more treatment options.

At what stage of AVN is hip replacement needed?

Hip replacement is typically recommended from Stage 3 onwards, when bone collapse has begun, or at Stage 4-5 when significant arthritis has developed. In younger patients with Stage 3 collapse, joint-preserving options including bone grafting procedures may be considered before committing to replacement. A specialist evaluation determines the most appropriate step for your specific stage.

What happens if AVN is left untreated?

Without treatment, AVN typically progresses through the Ficat-Arlet stages — from early bone changes to collapse, arthritis, and end-stage hip joint damage. The rate of progression varies. Most untreated cases eventually develop significant arthritis requiring hip replacement. Early diagnosis and appropriate management gives the best chance of a better long-term outcome.

Who is most at risk of getting avascular necrosis?

People who have received long-term or high-dose corticosteroids (including for COVID, asthma, autoimmune conditions), those with significant alcohol use, patients with previous hip fractures or dislocations, and those with certain blood disorders are at highest risk. Post-COVID AVN has emerged as a specific concern in India over the past few years.

Can children get avascular necrosis?

Yes. Perthes disease is avascular necrosis of the femoral head in children aged 4-10. It presents as a painless limp and hip or groin pain. Management in children is different from adults and focuses on preserving the shape of the femoral head during the healing process.

In early stages, AVN can be completely painless — found incidentally on imaging. As the condition progresses, groin pain develops, initially with activity and eventually at rest and at night. The pain typically worsens as bone collapse and arthritis develop. Pain that starts rapidly in a patient with risk factors for AVN should prompt urgent evaluation.

What is the difference between AVN and arthritis?

Osteoarthritis develops from gradual wear of the cartilage surface over decades. AVN involves death of bone tissue from disrupted blood supply, which then causes the bone to collapse — subsequently leading to cartilage damage and arthritis as a secondary consequence. AVN typically affects younger patients, progresses faster, and has identifiable contributing causes that arthritis does not.

What imaging is needed to diagnose AVN?

MRI is the most sensitive test for AVN and can detect it at the earliest stages before X-ray changes appear. Standard X-ray may be normal in early AVN. CT scan provides detailed bone detail and is used in planning for some procedures. MRI is the investigation of choice for suspected AVN — particularly when X-ray is normal but clinical suspicion is high.

Can physiotherapy help in AVN?

Physiotherapy does not reverse AVN or restore blood supply to dead bone. However, it plays an important role in managing symptoms, maintaining hip mobility and muscle strength, and optimising function — particularly in early stages and after surgical procedures. A specialist at Pure Ortho Hospitals, Sainikpuri will include physiotherapy as part of the overall management plan as appropriate.

Can I still work with avascular necrosis?

Many patients with early to moderate AVN continue working, particularly in desk-based occupations. Jobs requiring prolonged standing, heavy lifting, or significant walking may need modification. The ability to work depends on the stage of AVN, the level of pain, and the nature of the job. A specialist assessment gives a realistic picture of functional capacity and what modifications may be needed.

Does AVN always end in hip replacement?

Not always, but frequently. Early-stage AVN caught before collapse can sometimes be managed without replacement for years. However, the condition is progressive in most cases, and a significant proportion of patients eventually require hip replacement — particularly those diagnosed at Stage 3 or beyond. Modern hip replacement at Pure Ortho Hospitals, Sainikpuri produces excellent long-term outcomes.

Avascular Necrosis — Can It Be Treated Without Surgery?

Joint ReplacementSainikpuri, Hyderabad12 min read

Avascular necrosis AVN hip treatment without surgery Pure Ortho Hospitals Sainikpuri Hyderabad

The window for non-surgical AVN treatment is narrow — it exists only before the femoral head collapses. Early MRI diagnosis is what keeps that window open.

The first question almost every patient asks after being diagnosed with avascular necrosis of the hip is the same: do I need surgery? It is a reasonable question, and the answer matters enormously — because it depends almost entirely on how early the diagnosis was made.

Avascular necrosis (AVN) is the death of bone tissue from loss of blood supply to the femoral head — the ball-shaped top of the thighbone that forms the hip joint. Early-stage AVN, caught before the bone collapses, presents genuine options for joint-preserving management. Late-stage AVN, by which time the femoral head has collapsed and arthritis has developed, typically has one reliable treatment: hip replacement.

This blog answers the questions most frequently asked by patients at Pure Ortho Hospitals, Sainikpuri, Hyderabad about AVN — especially the ones who want to understand whether surgery can be avoided.

The Stage Determines Everything

AVN is not one condition — it is a spectrum of conditions, classified by stage. Treatment decisions in AVN are primarily determined by stage, not symptoms. This is why staging with MRI is the first essential step, even when pain is relatively mild.

Non-surgical options

Stage 1

MRI shows early changes. X-ray normal. Often no symptoms. Best window for joint preservation.

Non-surgical or core decompression

Stage 2

X-ray shows density changes. Femoral head shape intact. Conservative or core decompression.

Borderline — specialist decision

Stage 3

Crescent sign — subchondral fracture. Collapse beginning. Non-surgical rarely sufficient.

Surgical usually needed

Stage 4

Femoral head flattening. Joint surface damage. Bone grafting or replacement discussed.

Hip replacement

Stage 5

Significant arthritis. Joint space narrowed. Hip replacement the standard treatment.

What Non-Surgical Treatment for AVN Involves

When patients ask about "treatment without surgery," they usually mean they want to avoid hip replacement. This is a reasonable goal — and for Stage 1 and Stage 2 AVN, it is sometimes achievable. But it requires understanding what non-surgical management actually consists of.

Non-surgical management options for early AVN

Protected weight-bearing — reducing load through the affected hip using crutches or a walking aid, to prevent further mechanical stress on the weakening bone
Eliminating the cause — stopping or reducing steroid use (in consultation with the prescribing doctor), addressing alcohol use, treating underlying blood disorders
Bisphosphonate medication — reduces bone resorption and may slow the progression of bone collapse in early stages; evidence is supportive though not definitive
Lipid-lowering agents — used in steroid-related AVN where abnormal fat metabolism is a contributing factor
Anticoagulation — for AVN cases related to clotting disorders or hypercoagulable states
Physiotherapy — maintains hip range of motion and surrounding muscle strength; does not reverse AVN but supports function
Regular MRI monitoring — to assess whether the AVN is stable, progressing, or responding to management

The critical caveat: none of these measures reverse established necrosis or restore blood supply to dead bone. They are most relevant in the very earliest stages as an attempt to slow progression. Many patients diagnosed at Stage 1 or early Stage 2 still eventually progress to the point where surgery is needed — non-surgical management buys time, not a cure in most cases.

Core Decompression — What It Actually Is

Core decompression is frequently misunderstood. Patients often hear the term in the context of "avoiding hip replacement" and assume it is a conservative non-surgical measure. It is actually a surgical procedure — but a joint-preserving one, very different from hip replacement.

What core decompression involves

Performed under anaesthesia, usually as a day procedure
A drill is introduced through the femoral neck into the necrotic area of the femoral head, creating one or more channels
These channels relieve intraosseous pressure — an important contributor to pain and to the vascular compromise in early AVN
The channels also create pathways through which new blood vessel growth (neovascularisation) can occur
Bone marrow concentrate or growth factors may be injected at the same time to further support healing
Protected weight-bearing follows for 6-8 weeks after the procedure
Most effective in Stage 1 and Stage 2 AVN before bone collapse — success rate declines significantly once collapse has begun

Core decompression does not guarantee that hip replacement will be avoided. It offers the best chance of slowing or halting progression in Stage 1-2 AVN, but a proportion of patients still progress despite the procedure. It remains a valuable option because its recovery is relatively straightforward and it does not make future hip replacement more difficult.

Post-COVID AVN — A Specific Concern in India

Since 2021, orthopaedic clinics across India have seen a significant increase in AVN presentations in a new group of patients: those who received high-dose corticosteroids during COVID-19 treatment. The mechanism is well-established — corticosteroids disrupt fat metabolism in ways that compromise blood flow to the femoral head, and high-dose short-course steroid use during COVID has produced the same AVN risk as prolonged steroid use for other conditions.

Post-COVID AVN typically presents 3-12 months after steroid treatment, in patients who are often in their 30s and 40s and had no prior hip problems. Many have bilateral involvement — both hips affected. This population is particularly important to identify early because their age makes hip replacement a less attractive long-term option than for older patients, and the joint-preserving window is most valuable for them.

Get an MRI If You Had COVID Steroid Treatment and Have Hip Pain

Any groin or hip pain developing 3-18 months after COVID steroid treatment
Pain in both hips — bilateral involvement is common in post-COVID AVN
Hip pain in your 30s or 40s with no prior hip problems and COVID steroid history
Normal hip X-ray with persistent pain — X-ray misses early AVN

When Hip Replacement Becomes the Right Answer

Hip replacement should not be viewed as a failure of AVN management — it is the appropriate and reliable solution when AVN has progressed beyond the stage where joint-preserving treatment is viable. Modern hip replacement at Pure Ortho Hospitals, Sainikpuri produces excellent long-term outcomes, and a 40-year-old with Stage 4-5 AVN who receives a well-placed hip implant can expect decades of good function.

When hip replacement is the appropriate discussion

Stage 3 with significant bone collapse and persistent pain despite conservative management
Stage 4 — established femoral head deformity with joint surface damage
Stage 5 — significant arthritis with joint space narrowing
Any stage with unacceptable pain and functional limitation
Failed joint-preserving surgery — progression despite core decompression
Younger patients with advanced disease where bone grafting has been considered and deemed not viable

MRI is the gold standard for AVN staging — it identifies the condition at the earliest stage when the most options remain available.

Symptoms — What Brings Patients to a Specialist

Groin Pain

Deep, aching pain in the groin — the most common early symptom of hip AVN

Pain Worse with Activity

Initially only with walking or stairs, progressively developing at rest and at night

Stiffness

Reduced range of motion — difficulty crossing legs, putting on socks, getting in and out of a car

Limp

Develops as pain worsens — weight shifted to reduce load on the affected hip

Pain Radiating to Knee

Hip conditions frequently refer pain to the thigh and knee — in children especially, knee pain can be the presenting complaint of hip disease

Rapid Onset in Young Adults

AVN can develop and progress rapidly — particularly in post-COVID and steroid-related cases. Pain that worsens over weeks rather than months warrants urgent evaluation.

Frequently Asked Questions

Can avascular necrosis be treated without surgery?

Stage 1 and early Stage 2 AVN, before bone collapse occurs, may respond to non-surgical management including protected weight-bearing, eliminating contributing causes, and supportive medication. Core decompression is a joint-preserving surgical option for these stages. Once bone collapse has begun (Stage 3 onwards), hip replacement becomes the most reliable treatment.

What is core decompression for AVN?

Core decompression is a surgical procedure where channels are drilled into the necrotic area of the femoral head to relieve intraosseous pressure and stimulate new blood vessel growth. It is most effective in Stage 1 and Stage 2 AVN before collapse. It is not conservative treatment — but it is joint-preserving, requiring a much shorter recovery than hip replacement.

Is there a link between COVID steroids and AVN?

Yes — a significant number of post-COVID AVN cases have been documented in India, primarily in patients who received high-dose steroids during COVID treatment. Post-COVID AVN typically presents 3-12 months after steroid treatment, often affects both hips, and is seen in younger patients in their 30s and 40s. Any hip pain following COVID steroid treatment warrants early MRI evaluation.

How long can you live with avascular necrosis without treatment?

AVN is not life-threatening but it is progressive. Without treatment, most cases advance from early bone changes to collapse, arthritis, and eventually severe hip disability requiring replacement. The rate varies. Early treatment gives the best chance of slowing progression and preserving quality of life longer.

Does AVN affect both hips?

Yes — bilateral AVN is common, particularly in steroid-related and alcohol-related cases. The second hip may be asymptomatic when the first presents, which is why MRI of both hips is often recommended even when only one is painful. Finding and treating the contralateral hip early can significantly change outcomes.

What is the crescent sign in AVN?

The crescent sign is a specific X-ray finding — a thin dark line beneath the articular cartilage of the femoral head indicating subchondral fracture (Stage 3). Its presence signals that bone collapse is beginning. Joint-preserving non-surgical options become significantly less viable once the crescent sign appears.

What imaging is needed for AVN?

MRI is the investigation of choice — it detects AVN from the earliest stages before X-ray changes appear. Standard X-ray may be normal in Stage 1 AVN. A normal X-ray does not rule out AVN when clinical suspicion is high. MRI of both hips is recommended when one is diagnosed, as bilateral involvement is common.

At what stage is hip replacement needed for AVN?

Hip replacement is typically recommended from Stage 3 with established collapse, or at Stage 4-5 with significant arthritis. In younger patients at Stage 3, bone grafting procedures may be considered before replacement. A specialist evaluation at Pure Ortho Hospitals, Sainikpuri determines the most appropriate step for your specific stage and age.

Can physiotherapy help AVN?

Physiotherapy does not reverse AVN or restore blood supply. However, it maintains hip mobility and muscle strength, manages symptoms, and optimises function — particularly in early stages and after surgical procedures. It is an important component of overall AVN management alongside medical and surgical treatment.

What is bone grafting for AVN?

Bone grafting procedures place bone material into the necrotic area to provide structural support and stimulate new bone formation. The vascularised fibular graft brings living bone with its own blood supply into the necrotic area. These procedures are options for selected younger patients with pre-collapse disease who want to delay or avoid hip replacement.
