Tuberculous Arthritis of the Ankle

Tuberculosis (TB) is an infectious disease caused by the Mycobacterium tuberculosis complex (MTBC). Pulmonary TB is the most common form of presentation, but extrapulmonary tuberculosis (EPTB) contributes significantly to morbidity and mortality. Rarely, patients with EPTB develop a form of ankle or foot arthritis. The diagnosis of TB arthritis is often overlooked because of the insidious onset and the non-specific clinical symptoms. Prognosis is generally poor; early diagnosis and delivery of the most appropriate treatment is critical to avoid functional disability.

Tuberculous arthritis of the ankle has high morbidity but often goes undiagnosed.Tuberculous arthritis of the ankle can lead to degenerative changes in the bone and articular cartilage and even to joint collapse.Timely diagnosis and correct treatment are important to avoid functional disability.
