BENEFICIAL EFFECTS OF PERCUTANEOUS CORE DECOMPRESSION WITH BONE MARROW ASPIRATE CONCENTRATE IN THE CLINICAL MANAGEMENT OF AVASCULAR NECROSIS FROM STAGE III TO II: A 28 MONTHS FOLLOW-UP STUDY

Background and Clinical Significance: Avascular necrosis (AVN) of the femoral head is a progressive and debilitating condition resulting from compromised blood supply, leading to bone ischemia, structural collapse, and eventual joint degeneration. Delayed intervention frequently necessitates total hip arthroplasty (THA). Early-stage management using minimally invasive and regenerative approaches aims to preserve the native joint, alleviate symptoms, and prevent disease progression. Case Presentation: A 40-year-old male presented with left hip pain and was diagnosed with AVN of the femoral head, classified as Ficat–Arlet Stage III. Magnetic resonance imaging (MRI) revealed STIR hyperintensity involving the left femoral head, neck, and intertrochanteric region, with additional acetabular involvement and minimal joint effusion. The patient underwent a minimally invasive intervention consisting of percutaneous core decompression
