We report the results of a primary total hip arthroplasty (THA) in 7 patients with advanced active tuberculous arthritis of the hip and had lost the chance of preserving the hip without replacement surgery. Tuberculosis was confirmed in all cases by the culture or histological examination. All patients were treated with primary THA followed by antituberculous medications for 1 year. ⋯ The result was excellent in all patients according to the Harris Hip Score. Total hip arthroplasty in the tuberculous hip is a safe procedure and produces superior functional results compared with resection arthroplasty or arthrodesis. The results of primary THA in the selected patients was satisfactory as they rapidly recover from the disease.

The incidence of obesity in 1071 total hip arthroplasty (THA) patients and 1813 total knee arthroplasty (TKA) patients and its effect on perioperative morbidity were evaluated prospectively. Fifty-two percent of TKA and 36% of THA patients were obese (body mass index >or=30). The obese patients were significantly younger, with a higher proportion of obese TKA patients being women. ⋯ Higher postoperative infection rates were observed in patients with body mass index 35 or higher. The odds ratio was 6.7 times higher risk for infection in obese TKA patients and 4.2 times higher for obese THA patients. The increased risk of infection in obese patients undergoing total joint arthroplasty must be realized by both the patient and surgeon.
