Cartilage damage of the temporomandibular joint (TMJ) is a significant cause of chronic orofacial pain, jaw dysfunction, and reduced quality of life. TMJ disorders (TMDs) affect millions of individuals worldwide and often present with joint pain, clicking or locking, limited mouth opening, and progressive joint degeneration. Conventional treatments—such as occlusal splints, anti-inflammatory medications, physical therapy, and intra-articular corticosteroid injections—primarily focus on symptom management.
