Core Decompression ± Bone Grafting/Biomaterials

When there is early-stage avascular necrosis of the femoral head (ARCO I–II) and the head shape is still acceptable, symptoms continue to affect activity, or conservative treatment has limited effect, a specialist can assess whether to consider it. The decision focuses on the extent and location of necrosis, risk of collapse, condition of cartilage and acetabulum, response to previous treatment, overall health and weight-bearing needs, and whether suitable bone grafting/biological material conditions are available.
