Facet joint syndrome is a common yet frequently underdiagnosed cause of chronic spinal pain, particularly in the cervical and lumbar regions. The condition arises from degenerative changes and inflammation of the zygapophyseal (facet) joints, which play a critical role in spinal stability and motion. Facet-mediated pain is estimated to account for up to 40% of chronic low back pain cases. Conventional treatments—including physical therapy, anti-inflammatory medications, medial branch blocks, and radiofrequency ablation—often provide temporary symptom relief but do not address...

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. However, these approaches do not address the limited regenerative capacity of TMJ cartilage. In this context, regenerative...
