Understanding Hip Arthritis & Avascular Necrosis (AVN) Care
Avascular Necrosis (AVN / Osteonecrosis) occurs when the delicate blood supply to the spherical femoral head (hip ball) is disrupted, causing bone cells to die. Over time, the weakened bone collapses under normal body weight, turning a spherical ball into an irregular, flattened surface that destroys the hip joint. Common risk factors include corticosteroid use, alcohol consumption, post-COVID hypercoagulability, and prior trauma. Early diagnosis allows joint-preserving core decompression, while collapsed AVN (Stage III / IV) is cured completely with ceramic total hip replacement.
Personalized Evidence-Based Clinical Care
Every treatment protocol is tailored specifically to your diagnosis, anatomy, and lifestyle goals, combining cutting-edge surgical precision with structured physiotherapy for optimal long-term outcomes.
When Should You Consider Consultation for Hip Arthritis & AVN?
Specialist intervention is considered when joint pain or functional limitation significantly disrupts your daily life and conservative measures have been exhausted. Check if you experience any of the following:
Deep, throbbing groin, buttock, or inner thigh pain that worsens with weight-bearing or walking.
Pain that radiates down the front of the thigh to the knee, often mistaken for knee pain.
History of steroid medication use, heavy alcohol consumption, or post-COVID hip symptoms.
MRI or X-ray diagnosis of AVN (Ficat-Arlet Stage I, II, III, or IV).
Difficulty putting on shoes, getting out of low chairs, or walking without a limp.

“My surgical philosophy centers on biological preservation, anatomical restoration, and rapid functional recovery. By tailoring the intervention to each patient's unique anatomy and lifestyle, we achieve lasting pain relief and active mobility.”
The 4-Stage Precision Clinical Workflow
Comprehensive Clinical & Imaging Diagnosis
High-resolution 3T MRI mapping determining exact Ficat-Arlet staging and percentage of head involvement.
Tailored Minimally Invasive Approach
For pre-collapse AVN: minimally invasive fluoroscopic core drilling into the necrotic zone to relieve intraosseous pressure.
Anatomical Restoration & Tissue Decompression
Injection of autologous concentrated bone marrow stem cells to stimulate vascular re-growth.
Accelerated Functional Rehabilitation
For collapsed AVN: precision muscle-sparing total hip arthroplasty using Biolox Delta ceramic bearings.
Stage 05: Treatment Phase
Immediate post-operative weight-bearing with rapid elimination of chronic groin pain.
Treatment Modalities Offered
Dr. Vijay Kumar practices conservative joint-sparing protocols first, proceeding to advanced surgical intervention only when indicated:
Non-Surgical & Joint Sparing
- Protected weight-bearing with crutches in early Stage I disease
- Bisphosphonate and vasoactive medical therapy to stabilize bone turnover
- Targeted physical therapy maintaining hip range of motion
- Platelet-Rich Plasma and stem cell research-backed adjunctive therapy
Specialised Surgical Procedures
- Percutaneous Core Decompression with Bone Marrow Aspirate Concentrate (BMAC) for early pre-collapse AVN (Stage I/II)
- Biological Non-Vascularized / Vascularized Bone Grafting
- High-Performance Ceramic Total Hip Replacement for collapsed femoral head (Stage III/IV)
- Dual Mobility Arthroplasty for advanced cases with compromised soft tissues
Recovery Timeline & Mobility Milestones
Week 1: Elimination of deep arthritic groin pain, independent walking.
Weeks 2–4: Progressive full unassisted walking, return to driving and office duties.
Months 2–3: Resumption of cycling, swimming, gym workouts, and active lifestyle.
Months 6+: Long-term follow-up confirming robust bone integration and pain-free mobility.
