Efficacy of autologous stem cell therapy in femoral head avascular necrosis: a comparative study.

The treatment of avascular necrosis of the femoral head varies according to various staging methods. Early diagnosis of the disease and correct treatment are very important for the patient's quality of life in the future. In our research, we found that patients who received both core decompression and stem cell implantation for early-stage avascular necrosis of the femoral head exhibited decreased pain at the 6-month, 1-year, and 2-year follow-up examinations. Additionally, their hip function improved at the 24-month mark according to the HHS evaluation.
