Construction of strontium-loaded injectable lubricating hydrogel and its role in promoting repair of cartilage defects

Injuries such as articular cartilage defects are prevalent factors in the development and progression of joint diseases. The discontinuity of the articular surface due to cartilage defects significantly accelerates the onset of arthritis. Cartilage tissue-engineered scaffolds are essential for restoring the continuity of the articular surface. This study presents a dual-network hydrogel, GelMA-FT/Sr
