Prosthetic knee infection in the young immigrant patient--do not forget tuberculosis!

Skeletal tuberculosis (TB) frequently masquerades as more common etiologies and can be difficult to diagnose. We describe a case of TB knee arthritis in a young Haitian-born woman in whom the diagnosis was not initially suspected, resulting in treatment with total knee arthroplasty that subsequently failed. A long course of medical and surgical therapies was then necessary to treat this patient. Issues in the diagnosis and management of TB in the native and prosthetic knee joint are presented.
