Arthroscopic Core Decompression With Allogeneic Bone Grafting for Femoral Head Osteonecrosis and Femoral Head‐Neck Junction Cysts

Osteonecrosis of the femoral head is a debilitating condition that can lead to cysts at the head-neck junction. Without timely intervention, the disease often progresses to femoral head collapse, ultimately necessitating hip replacement surgery. This article describes a hip preservation treatment method that involves core decompression by drilling small holes in the femoral neck and hernia sac, followed by filling femoral pits with allogeneic bone. The advantage of this technique lies in its ability to reduce intracapsular pressure, enhance blood circulation, and stabilize the femoral head, thus preventing collapse. Additionally, the blood released during core decompression nourishes the transplanted bone, further supporting its integration and effectiveness.
