Abstract: Background: Avascular necrosis (AVN) of the hip is a disease characterized by vascular disruptions, where 67% of untreated cases may lead to the collapse of the femoral head. None of the current approaches, such as core decompression (CD), vascularized bone grafting, osteotomy, tissue implantation, and other methods, have been proven fully effective in delaying the progression of osteonecrosis. Recent findings indicate that bone marrow stem cells (BMSCs) have significant potential to regenerate necrotic tissue and prevent the progression of AVN in the hip. This study aims to evaluate the efficacy, side effects, treatment failure rate, most effective treatment stage of AVN hip, and application technique to treat AVN hip. Method: We performed this systematic review and meta-analysis from randomized controlled trials (RCTs) and sources published between 2013 and 2023 from six databases. The literature searching method was based on predetermined PICOS, study eligibility criteria, and PRISMA guidelines. The extracted data were then assessed quantitatively using R Studio with Harris hip score (HHS), Visual analog scale (VAS), the collapse of the femoral head, and conversion of total hip arthroplasty (THA) as the outcomes of interest, then qualitatively using RoB Tool, the extracted data were analyzed using R Studio. Result: A total of 12,939 records were identified through database searching. After the removal of duplicates and non-randomized studies using automation tools, 4,846 articles were screened. Following title and abstract review, 10 studies met the eligibility criteria and were included in the systematic review and meta-analysis, comprising 593 patients and 779 hips. Conclusion: Currently established AVN hip treatments are proven to be less effective. The findings strongly support that giving a BMSC at the early-stage AVN hip could improve the patient’s clinical outcome and have fewer side effects and treatment failure compared to conventional treatment.
