Every time a joint slips or dislocates, the soft tissue connected to that joint — tendons, ligaments, muscle, fascia, blood vessels — all stretches. Because of the structural defect in collagen, all that connected tissue is stretched beyond what normal should be; high resolution MRIs reveal microtrauma, microscopic tears that start up the inflammation and coagulation cascades. But because each joint can subluxate over and over in just a single day, these microtraumas happen over and over in the same tissue without healing successfully. - Dr. Clair Francomano
