Objectives: Osteoarthritis (OA) is a common joint disorder and has a strong relationship with obesity. Although the patients should be expected to mobilize more easily and lose weight after arthroplasty procedures, we hypothesized that the body mass index (BMI) usually increases in the post-operative period of total joint arthroplasty in the lower extremity. We aimed to evaluate the BMI changes of arthroplasty patients and impact of BMI changes in TKA and THA patients' functional results.

Methods: 513 patients who were operated due to gonarthrosis, coxarthrosis, aseptic loosening of the total knee and hip arthroplasties were evaluated prospectively. Patients were operated by three surgeons in three medical centers. Patients who were between 50-65 years of age and who were underwent total knee arthroplasty (TKA), total hip arthroplasty (THA), revision knee arthroplasty (RTKA), revision hip arthroplasty (RHA) were included to our study. At the preoperative period, functional joint scores, height, weight and body mass indexes of all patients were noted. We used the Knee Society Score for knee and Harris Hip Score for hip patients. Postoperative functional scores were measured at 1, 6 and 12 months and recorded separately at outpatient controls.

Results and Conclusion: Arthroplasty patients had weight gain and had increase in BMI index in the postoperative 1, 6 and 12 months. (Preop mean BMI: 27.7, Postop 1 month: 27.8, Postop 6 months : 28.1 and Postop 12 months: 28.6) (p<0.01) Worse functional results had obtained in the patients that had BMI increase. However these correlation was statistically significant only in the postoperative 6th month control. To prevent the negative functional effects of this weight gain during postoperative period, arthroplasty patients should be advised for weight control and in patients that tend obesity should be consulted with a dietician.
