    Abstract: <p style="text-align:justify">A vascular necrosis (AVN) of the femoral head is a condition where blood supply to this vital area is diminished. This leads to severe bone damage, micro fractures and ultimately the collapse of the articular surface in more advanced stages. AVN is responsible for around 10% of total hip replacements, emphasizing the need for early intervention. Core decompression is a widely accepted surgical technique for the treatment of early‐stage AVN, demonstrating favourable outcomes in pre‐collapse phases (FICAT and ARLET stages 0‐II). However, there is a notable decline in efficacy when this procedure is performed in advanced stages (FICAT and ARLET stage III or IV). This prospective study was done in Department of Orthopaedics, Sree Mookambika institute of medical sciences with 20 AVN patient. Patients with idiopathic AVN of femoral head, stage 1, 2A, or 2B were included in the study. Patients with stage 3 or 4 AVN of femoral head were excluded from the study. Outcomes were evaluated based on the Visual Analog Scale for pain and hip function was measured using the Modified Harris Hip scores. The mean visual analog scale (VAS) scores showed a considerable decline from 8.75&plusmn;0.45‐3.25&plusmn;0.52. Accordingly, the mean Modified Haris Hip Score increased from 47.18&plusmn;3.84 preoperatively to 89.14&plusmn;5.03 at 24 months, indicating significant improvement in hip range of motion and functional activities. Core decompression with BMAC is effective method to treat early stages of AVN.</p>
