• prolonging the drug residence time. The intra-articular administration of these nanocapsules in a rat model of OA remarkably decreased knee swelling and improved cartilage repair [65]. In another study, to suppress the expression of pro-inflammatory cytokines in inflamed cartilage, researchers designed poly

• (NIPAm-AMPS) NPs for the delivery of cell penetrating anti-inflammatory peptides, which selectively target defective sites [66]. In this study, the results showed that an anti-inflammatory peptide-loaded NP could selectively and effectively reduce the expression of pro-inflammatory cytokines within the
