Background: The aim is to study the clinical features and diagnosis of primary extra-spinal musculoskeletal manifestations of tuberculosis (TB) in otherwise healthy individuals. Methods: In this retrospective study of 10 years duration electronic database and case records of patients with musculoskeletal TB were analyzed. Patient's positive for HIV and rheumatic diseases with or without immunosuppressive drugs or biological agents were excluded from the study. Results: Fifty-one patients were identified with the mean age at presentation of 33.35 years (range 4–72), male: female ratio of 1.1:1 and mean duration of disease was 14.65 months (range, 0.25–120). The most frequent manifestation was articular (arthritis/arthralgia n = 40, monoarthritis n = 28, oligoarthritis n = 10, polyarthralgia n = 2) followed by tenosynovitis (n = 6), tuberculous osteomyelitis (n = 5), isolated bursitis (n = 1), and pyomyositis (n = 1). Poncet's disease was diagnosed in five patients. Disseminated TB was detected in four patients. Pain (n = 50) followed by swelling of the involved site (n = 37) were the most common presenting symptoms. Fever was present in 15 (29.4%) patients. Nine patients had a previous history of TB. Concurrent pulmonary TB was present in two patients. Lymph node enlargement was present in 12 (23.5%) patients. A definite diagnosis of musculoskeletal TB was made in 31 (61%) patients and probable TB in 20 (39%) patients. Conclusion: Musculoskeletal manifestations of TB can occur at any age. Chronic monoarthritis is the most common presentation; however, oligoarthritis and/or tenosynovitis may be a presenting manifestation. The absence of fever should not discourage the diagnosis of musculoskeletal TB.
