INTRODUCTION: TB of the knee is often associated with marked morbidity because of its late and non-specific presentation. The use of TKA (total knee arthroplasty) in the face of a previous tuberculous knee infection has been criticized with multiple controversies. Therefore, the purpose of this review is to assess: (1) clinical outcomes, (2) radiographic outcomes, and (3) complications of TKA in the face of a previous healed TB infection. Our analysis has demonstrated that previous TB infection of the knee joint does not preclude TKA if indicated and suggests placing patients who have ESR or CRP results out of normal range on pre-operative anti-TB prophylactic antibiotic for a minimum of 2 weeks. In case of local recurrence following TKA, antibiotic therapy alone can be an effective treatment option. AREAS COVERED: We examined reported outcomes of performing TKA in patients with previous TB infection of the knee. Different strategies recommended by different authors to maximize the success of TKA in this situation are also discussed. EXPERT COMMENTARY: TKA has been proven to be effective in patients who are status post tuberculous arthritis when thoughtful patient selection and peri-operative planning is conducted. Tuberculosis continues to have a rising incidence and increasing spread of multi-drug resistant strains. DOI: 10.1080/17434440.2018.1520633
