Abstract:

Knee osteoarthritis (KOA) is a chronic degenerative joint degeneration commonly seen in the elderly and is associated with articular cartilage degeneration and subchondral bone remodeling. At present, the treatment of KOA is based on step therapy, including non-surgical primary treatment, pharmacological treatment, restorative treatment, and reconstructive treatment. Mesenchymal stem cells (MSCs) are widely used to treat many diseases, including KOA, because of the great proliferative potential. Extracellular vesicles (EVs) are a promising treatment for KOA by promoting the regeneration of articular cartilage. This review provided feasible theoretical supports for the treatment of KOA with EVs by discussing the mechanism of generation and preparation of EVs, the application of EVs in the treatment of KOA, the efficacy and safety of EVs in the treatment of KOA, and the future outlook of EVs in the treatment of KOA.

Key words: Osteoarthritis, Mesenchymal stem cells, Extracellular vesicles, Cartilage, articular
