The outcomes of total knee arthroplasty following the incidental finding of tuberculosis and its treatment: A prospective study.

Extrapulmonary tuberculosis (EPTB) accounts for 16 % of tuberculosis cases globally, with knee joint tuberculosis more prevalent in underdeveloped nations. Total knee arthroplasty (TKA) is commonly used to treat tubercular arthritis of knee, however, there is a marked paucity of research on the outcomes after an incidental diagnosis. The aim of the study is to investigate the outcomes of total knee arthroplasty after an incidental diagnosis of tuberculosis and its management. A prospective-observational study was conducted in NCR-Delhi from May 2019 to June 2023, wherein 533 patients had synovial tissue abnormalities and 11 patients reported with positive histopathological examination (HPE) for knee tuberculosis. All the patients whose informed consent was obtained were put on a twelve-month standard treatment (2HRZE or S/10HR) according to World Health Organization (WHO) guidelines for extrapulmonary TB after TKA and were monitored for the outcome of treatment, any postoperative complication, or implant failure. The mean age of the patients was 63 ± 13 years and 72.7 % of patients were female. The mean hemoglobin, Body Mass Index (BMI), and Erythrocyte Sedimentation Rate (ESR) values were 10.29 ± 1.36 mg/dl, 29.78 ± 6.1 kg/m We concluded from this study that any abnormalities in ESR, CRP level prior to, and bone tissue or synovial tissue during operative procedure should be considered for articular tuberculosis and managed according to guidelines. This will make replacement procedures more sustainable and effective by lowering the risk of post-operative infection or implant-related complications and improving patients' quality of life.
