Abstract:

BACKGROUND: A variety of hip-preserving treatments for early osteonecrosis of the femoral head have been emerged. However, the favorite hip-preserving method is still under investigation. Core decompression combined with stem cell transplantation is a hip-preserving treatment for early osteonecrosis of the femoral head. However, its effectiveness and influencing factors are quite diverse reported in existing clinical studies.
OBJECTIVE: To evaluate the mid-long-term effects of core decompression combined with stem cell transplantation in the treatment of osteonecrosis of the femoral head.
METHODS: This was a retrospective study with the approval by the Ethics Committee of Xingtai People’s Hospital Affiliated to Hebei Medical University, China (approval No. 2018-JS037). From 2008 to 2012, 65 of 95 patients with osteonecrosis of the femoral head were treated with core decompression with bone marrow mesenchymal stem cell transplantation. There were 53 males and 12 females, with the mean age of 43.1(20-61) years. There were 65 hips, including 29 defined as ARCO stage I and 36 as ARCO stage II, as well as 15 as ARCO type A, 33 as ARCO type B, and 17 as ARCO type C. The mean follow-up period was 7.5 (6.5-10.1) years. Post-treatment collapse rate and hip replacement rate were assessed, and risk factors for post-treatment collapse were analyzed through a multivariate logistic regression analysis.
RESULTS AND CONCLUSION: The overall collapse rate of the femoral head was 46% (30/65). For stage I and stage II collapses, the collapse rates of the femoral head were 34.5% (10/29) and 55.6% (20/36), respectively. For ARCO type A, B and C, the collapse rates of the femoral head were 26.7%(4/15), 42.4%(14/33), and 70.1%(12/17), respectively. The hip replacement rate of the 65 hips was 23% (15/65). In the multivariate logistic regression analysis, postoperative rate of femoral head collapse was significantly correlated with body mass index, preoperative ARCO stage and type (P < 0.05), which are defined as the risk factors for femoral head collapse.
