Enhanced therapeutic potential of a self-healing hyaluronic acid hydrogel for early intervention in osteoarthritis.

Osteoarthritis (OA) is characterized by symptoms such as abnormal lubrication function of synovial fluid and heightened friction on the cartilage surface in its early stages, prior to evident cartilage damage. Current early intervention strategies employing lubricated hydrogels to shield cartilage from friction often overlook the significance of hydrogel-cartilage adhesion and enhancement of the cartilage extracellular matrix (ECM). Herein, we constructed a hydrogel based on dihydrazide-modified hyaluronic acid (HA) (AHA) and catechol-conjugated aldehyde-modified HA (CHA), which not only adheres to the cartilage surface as an effective lubricant but also improves the extracellular environment of chondrocytes in OA.
