title: The great mimic again? A case of tuberculosis knee.
abstract: Tuberculosis (TB), once a disease confined to undeveloped or developing nations is currently in resurgence due to pandemic human immunodeficiency virus infection and immigration from endemic areas. TB is also known as the 'great mimicker'. Extra-pulmonary tuberculosis affecting the knee is rare in all forms of TB (0.1-0.3%). Here, we report a case of isolated highly erosive TB knee in a previously fit Burmese migrant worker. He presented with after a history of fall into a drain. The patient also reported pain and swelling over his left knee for the previous three years. He had been treated for a bacterial infection of the knee in another hospital but defaulted due to financial constraints. Arthrotomy of the knee was performed including washout. Diagnosis of TB of the knee was made based on the synovial fluid and tissue culture. Treatment with antituberculosis drugs was then initiated.
