Abstract:
Temporomandibular joint (TMJ) involvement is quite frequent in juvenile idiopathic arthritis (JIA). We describe a 15-year-old girl with isolated TMJ arthritis presenting as a unique manifestation of JIA, and its successful treatment. She underwent arthroscopic synovectomy followed by intraarticular steroid injection. Early use of synovectomy and intraarticular steroids in TMJ arthritis may reduce pain, improve jaw function, and prevent irreversible deformities.

Three primary contributing factors have been identified.
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
