Patient-Specific Factors Predicting Outcome of Temporomandibular Joint Arthroscopy: A 6-Year Retrospective Study

The results indicate that psychiatric comorbidities, high self-graded global pain, bilateral masticatory muscle tenderness, and small MIO predict an unsuccessful outcome after arthroscopic lysis and lavage. These factors could be indicators for chronic pain disorders, including chronic myofascial pain, increased pain sensitivity, and decreased coping abilities, associated with a poor outcome.
