Traditional treatment methods such as surgical repair and drug therapy have certain limitations and are difficult to achieve ideal repair results. In recent years, with the continuous development of biomaterials and tissue engineering technology, hydrogel microspheres as a new therapeutic strategy have gradually attracted the attention of researchers. Hydrogel microsphere is a kind of drug carrier with excellent biocompatibility and degradability, which can wrap the drug inside the microsphere by physical or chemical methods. In terms of drug release mechanism, hydrogel microspheres achieve controlled release of exosomes through swelling, degradation and other ways. This release mechanism can enable extracellular vesicles to continuously and stably function in the joint area, improving treatment effectiveness. This article reviews the research progress of the application of cellular and non cellular (cytokines, protein peptides, drugs, exosomes and RNA) hydrogel microspheres in articular cartilage in recent years, summarizes the limitations of current research and future development direction by combing and analyzing relevant literature, and provides new ideas and methods for the treatment of articular cartilage injury.展开更多
