Abstract:

BACKGROUND: A large number of clinical trials have found that the number of bone marrow stem cells at the femoral neck and proximal femur in patients with osteonecrosis of the femoral head is significantly reduced, accompanied by decreased activity, which causes a significant decrease in osteogenic capacity that the necrotic bone cannot be effectively repaired after absorption, leading to the collapse of the femoral head.
OBJECTIVE: To probe into the early clinical efficacy of autologous peripheral blood mononuclear cell transplantation with porous core decompression for treatment of avascular necrosis of the femoral head.
METHODS: Forty-five patients with avascular necrosis of the femoral head (49 hips) were enrolled in this study, and underwent autologous peripheral blood mononuclear cell transplantation with porous core decompression. After treatment, pain scores, Harris hip score, scores on the satisfaction of patients were evaluated, as well as X-ray, CT and MRI examinations.
RESULTS AND CONCLUSION: All the patients received a follow-up visit of 11-14 months, averagely (12.5±0.6) months. During the follow-up, there were no complications and serious adverse reactions. Postoperative pain scores and Harris scores were both improved significantly compared with preoperative ones (P < 0.05). At 12 months after treatment, the excellent satisfaction rate was up to 92%. Patient’s MRI low signal region accounting for a percentage of the volume of the femoral head was decreased from (40.1±7.34)% preoperatively to (20.23±5.4)% at 6 months postoperatively, and there was a significant difference (P < 0.05). These findings indicate that autologous peripheral blood mononuclear cell transplantation with porous core decompression for treatment of avascular necrosis of the femoral head has significantly clinical effects at early stage, which can obviously reduce joint pain, improve and restore hip joint function, and delay progression of disease.
