A total of thirty-three patients who were morbidly obese were in one group and in another group 66 non-obese patients were taken into consideration. morbidly obeseAfter the completion of study, the results were compared and it was observed that the rate of reinfection was extremely high in morbidly obese patients (18%) when compared to the non-obese patients (2%). Almost a similar response was seen in case of revision as it was 42% in morbidly obese patients and 11% in non obese patients. Reoperation for any specific reason was seen in 61% of morbidly obese patients and 12% in case of non obese patients. To conclude, the study determined the fact that morbidly obese patients are at a significantly higher risk of developing complications of reinfection or reoperation after total hip arthroplasty for periprosthetic joint infection as compared to those who are non obese.
