Core Tip

Core Tip: Microfragmented adipose tissue (MFAT) has been successfully applied to treat different types of orthopedic diseases. To assess the efficacy and safety of MFAT with arthroscopic surgery in patients with knee osteoarthritis (OA). In this study, patients’ own MFAT combined with arthroscopic surgery was used to promote recovery from OA. Our findings provide evidence supporting the safety and feasibility of this approach in treating knee OA.
