Adipose Derived Stem Cells in Orthopaedics: History and Current Applications

Abstract

Context: Some studies have shown promising results with adipose-derived stem cell treatments for orthopaedic problems as a nonsurgical treatment option or an augmentation of surgical treatment. Purpose: Review of the history and background, preparation methods, and current applications of adipose-derived stem cells in orthopedics. Provide critical appraisal of the available evidence for the use of Adipose Derived Stem Cells. Results: Most of the studies utilizing adipose-derived stem cells are case series or meta-analyses with a small number of studies, therefore presenting a risk of selection bias. In cases of femoral head avascular necrosis and meniscal repair, no systematic review or meta-analysis has been published and available evidence is derived from smaller studies. Almost every review article concluded that large, multicenter, randomized control trials are needed to establish the value of adipose-derived stem cells in orthopaedics. Conclusion: There is a need in orthopaedics for treatment modalities that increase biological healing potential for some pathologies and adipose derived stem cells represent a potential modality for such a purpose. However, there is a lack of high quality and robust evidence regarding the efficacy and safety of this treatment modality in orthopaedic applications. The use of adipose derived stem cells in orthopaedics requires additional studies of higher quality before they can be considered an appropriate treatment option. Strength of Recommendation: Level C for use of Adipose-derived stem cells in orthopaedics.
