Sustained release of magnesium ions mediated by injectable self-healing adhesive hydrogel promotes fibrocartilaginous interface regeneration in the rabbit rotator cuff tear model

The fibrocartilaginous enthesis regeneration after rotator repair is still a major challenge. Although magnesium-based alloy orthopedic implant is effective to promote fibrocartilage formation at the tendon-bone interface in the anterior cruciate ligament reconstruction model, it was limited in the rotator cuff repair for its special anatomical structure. Herein, we developed a multifunctional self-healing magnesium ions-quaternized...
