Abstract:

Non-traumatic avascular necrosis of the femoral head (ONFH) is a difficult-to-treat disease that significantly impacts patients’ quality of life. Due to its complex pathogenesis and limited treatment options, pharmacotherapy has shown unique advantages in the treatment of ONFH. Angiostatin, as a bioactive substance with angiogenic-promoting effects, has gradually gained attention in the research on the treatment of ONFH. This article reviewed the research progress of angiostatin in treating ONFH, pointing out that angiostatin may help restore blood supply to the femoral head by promoting angiogenesis and improving blood supply, thereby alleviating clinical symptoms. Therefore, angiostatin plays a positive role in the expression of related factors in vascular intervention and provides a new perspective for the treatment of ONFH.
