ROS-responsive injectable hydrogel microspheres (KGN/Dex-TSPBA@WHMs). A The KGN/Dex-TSPBA@WHMs ameliorates OA through ROS-responsive nanoparticles reacting with OA-induced intracellular ROS. B The dihydroethidium (DHE) staining results show the ROS-eliminating ability of KGN/Dex-TSPBA@WHMs. C The X-ray images of each group taken 5Â weeks after the treatment.
