Avascular Necrosis (AVN)—also known as osteonecrosis—is a serious condition in which bone tissue dies due to lack of blood supply. Most commonly affecting the hip joint, AVN can also impact the knee, shoulder, or ankle, leading to pain, joint collapse, and ultimately arthritis or disability if not treated early.
While traditional treatments often include surgery or joint replacement, RegenOrthoSport offers advanced non-surgical AVN Treatment using regenerative medicine—including Platelet-Rich Plasma (PRP) and Stem Cell Therapy—to preserve your joint, restore function, and delay or prevent the need for surgery.
With expert care from Dr. Venkatesh Movva, our clinics in Hyderabad, Mumbai, and Bangalore provide advanced non-surgical AVN treatment options for all stages of the condition.
What Is Avascular Necrosis (AVN)?
Avascular Necrosis occurs when blood flow to a bone is disrupted, causing the bone cells to die. Over time, this leads to bone weakening, collapse of the joint surface, and severe arthritis if left untreated.
AVN is most commonly found in:
- Hip (femoral head): The hip is the most commonly affected joint in AVN, where the blood supply to the femoral head (the ball of the hip joint) is disrupted, leading to progressive collapse of the bone, groin pain, and stiffness, often making walking or standing painful.
- Knee: AVN in the knee usually affects the femoral condyles (lower thigh bone) and can cause localized pain during bending, squatting, or climbing stairs, often misdiagnosed as arthritis in the early stages.
- Shoulder: In the shoulder, AVN typically targets the humeral head (top of the arm bone), leading to dull or sharp pain with arm movement, difficulty lifting the arm overhead, and eventually loss of shoulder function if untreated.
- Ankle: Though less common, AVN in the ankle—especially the talus bone—can result in persistent ankle pain, swelling, and instability, often following trauma or fractures, and may significantly affect mobility and balance.
What Causes AVN?
AVN can develop due to various underlying factors:
- Trauma: Fractures or dislocations can damage blood vessels to the bone.
- Steroid Use: Long-term or high-dose corticosteroids are a leading non-traumatic cause.
- Excessive Alcohol Consumption: Alcohol interferes with fat metabolism, leading to blood vessel blockages.
- Medical Conditions: Lupus, sickle cell anemia, pancreatitis, HIV/AIDS, and autoimmune disorders.
- Radiation Therapy or Chemotherapy: Can impair blood supply to the bone.
- Idiopathic (Unknown Causes): In many cases, the cause remains unclear.
Symptoms of Avascular Necrosis
In its early stages, AVN can be painless. As the condition progresses:
- Persistent joint pain, especially in the groin (hip) or thigh
- Pain worsens with weight-bearing or movement
- Stiffness or limited range of motion
- A noticeable limp or instability
- Joint collapse or arthritis in later stages
How Is AVN Diagnosed?
At RegenOrthoSport, we use a multi-step diagnostic process:
- Medical history and symptom analysis
- Physical examination of joint function
- MRI scan (most sensitive for early-stage AVN)
- X-rays (helpful in advanced stages when bone collapse has occurred)
Stages of Avascular Necrosis (AVN)
AVN progresses through four main stages:
| Stage | Description | Symptoms |
| Stage 1 | Early AVN; blood supply is disrupted, but X-ray is often normal | Mild or no pain, usually diagnosed with MRI |
| Stage 2 | Bone begins to harden and lose shape; X-ray may show early changes | Increased discomfort, especially during movement |
| Stage 3 | Structural collapse of bone; visible joint damage | Persistent pain, limited mobility, limp develops |
| Stage 4 | Complete joint collapse and arthritis | Severe pain, loss of joint function, often requires joint replacement |
Why Early Intervention Matters
Early diagnosis and treatment can prevent joint collapse and avoid the need for surgery. Patients diagnosed in Stage 1 or 2 are the best candidates for non-surgical regenerative therapies, which can restore circulation, preserve the joint, and improve outcomes.
Regenerative Treatment Options for AVN at RegenOrthoSport
We use advanced orthobiologic therapies to heal damaged bone tissue, improve joint function, and slow AVN progression—without surgery.
1. Platelet-Rich Plasma (PRP) Therapy
PRP is prepared from your own blood and injected into the affected joint or surrounding tissue. It contains powerful growth factors that:
- Stimulate healing of bone and cartilage
- Reduce inflammation
- Improve blood supply and joint mobility
- Alleviate pain without steroids
Best suited for:
- Stage 1 or 2 AVN
- Patients with mild to moderate symptoms
- Those looking for a drug-free, non-surgical solution
2. Stem Cell Therapy for AVN
Stem Cell Therapy involves extracting cells from your bone marrow, processing them, and injecting them into the necrotic area to stimulate bone regeneration.
How it helps:
- Rebuilds damaged bone structure
- Enhances vascularization (blood supply)
- Delays or prevents joint replacement surgery
Ideal for:
- Stage 1, 2, and early Stage 3 AVN
- Hip AVN, knee AVN, and shoulder AVN
3. Bone Marrow Stem Cell for AVN Treatment
This advanced therapy concentrates stem cells, platelets, and healing factors into a powerful injection. Delivered precisely to the AVN site, BMAC can:
- Reverse early AVN damage
- Reduce joint pain and stiffness
- Enhance long-term joint preservation

FAQs About Avascular Necrosis Treatment
Can AVN be cured without surgery?
In early stages, AVN can often be managed or reversed with regenerative therapies like PRP and Stem Cell Therapy.
How soon should AVN be treated?
The earlier, the better—treating AVN in Stage 1 or 2 gives the best chance of joint preservation.
Is PRP or Stem Cell Therapy painful?
These are minimally invasive procedures with local anesthesia; patients generally tolerate them well.
How long does it take to see results?
Most patients notice improvement in pain and mobility within 4–8 weeks, with continued benefits over time.
Do you treat hip AVN only?
No—we treat AVN of the hip, knee, shoulder, and ankle with customized protocols.
Is this safe for young patients?
Yes—early intervention is especially beneficial for younger individuals to avoid premature joint replacement.
Can I return to sports after AVN treatment?
Yes, with proper rehab and guidance, many patients return to full activity post-regenerative therapy.
