Prosthetic joint infection due to Mycobacterium tuberculosis: report of three cases

Abstract

Prosthetic joint infection due to Mycobacterium tuberculosis is uncommon. We describe three patients with delayed tuberculous prosthetic joint infection and review the eight other cases reported in the English-language literature. Infection results from local reactivation, which can occur up to 40 years after the initial infection, or from hematogenous spread. The diagnosis is often delayed because it is not considered in the initial evaluation, because it is difficult to confirm microbiologically, or because other bacteria may be isolated from the synovial fluid and thus be considered the etiology of the infection. Treatment usually consists of removal of the prosthesis in addition to administration of antituberculous agents.
