Tuberculous arthritis

Chronic, slowly progressive infection of joints (such as hips, knees, ankles, or intervertebral disks) by Mycobacterium tuberculosis. The organism usually spreads via the blood or from osteomyelitis in an adjacent bone. The macrophage and lymphocyte response to the mycobacterium destroys the bone along the joint margins, resulting in progressive pain, fibrosis, and restricted movement.
