The Relationship Between Temporomandibular Joint Synovitis and Adhesions: Pathogenic Mechanisms and Clinical Implications for Surgical Management

Synovitis and adhesions are commonly present in the temporomandibular joints of patients requiring arthroscopic surgery due to painful limitation of mandibular movement. Excessive mechanical stress on the temporomandibular joint leads to maladaptive responses in the articular and synovial tissues, ultimately leading to synovitis, osteoarthritis and the formation of adhesions. An understanding of the pathogenic mechanisms that lead to synovitis, osteoarthritis and adhesions has important clinical implications for the nonsurgical as well as surgical management of patients suffering from these disorders.
