CHRONIC ANKLE MONOARTHRITIS DUE TO TUBERCULOSIS IN AN IMMUNOCOMPETENT INDIVIDUAL

Tuberculosis (TB) is an infectious disease, transmitted almost exclusively by cough aerosol, caused by the Mycobacterium tuberculosis complex, and characterised pathologically by necrotising granulomatous inflammation usually in the lung, although almost any extrapulmonary site can be involved. About 1-3% of all cases of TB involve bones and joints and only 10% of osteoarticular TB affects the foot and ankle. The diagnosis of TB arthritis is often overlooked because of the insidious onset and the non-specific clinical symptoms, leading to a high grade of morbidity due tue degenerative changes of the articular cartilage and the bone.
