Core Tip
Core tip: Although the patients should be expected to mobilize more easily and loose weight after arthroplasty procedures, we hypothesized that the body mass index (BMI) usually increases in the postoperative period of total joint arthroplasty of the lower extremity. We aimed to evaluate the BMI changes in arthroplasty patients and impact of BMI changes on functional results in total knee arthroplasty and total hip arthroplasty patients. In our study, we determined that lower extremity arthroplasty patients gained weight during the postoperative period and this weight gain deteriorated functional outcomes of the patients. This correlation was statistically significant at the 6th month postoperatively (P = 0.03).
