THE RESULTS OF TOTAL HIP ARTHROPLASTY IN OVERWEIGHT PATIENTS

Abstract

This article discusses the results of a study aimed at evaluating the treatment compliance of overweight and obese patients after total hip arthroplasty (THA) by assessing infection rates and using the EQ-5D-5L and Oxford Hip Score (OHS) scales. The study included 106 patients who underwent total hip arthroplasty. Patients were divided into three groups based on their body mass index (BMI): 50 patients with a normal BMI (Group I), 24 patients with high BMI (Group II), and 32 patients with obesity (Group III). To assess quality of life, the EQ-5D-5L survey was used. The Oxford Hip Score (OHS) was utilized to predict the utility values of EQ-5D-5L. Immediately after surgery and at 3 and 6 months, no statistically significant differences were found based on EQ-5D-5L scores. However, immediately after surgery, there were no significant differences in OHS scores across the groups. Six months after surgery, the OHS scores for Group I were significantly higher compared to Group II (t=2.08, p=0.0410, p<0.05). Patients in better health had more favorable utility score predictions. Therefore, additional research on prognostic models for patients with poorer health is recommended. The study found statistically significant improvements in physical and mental health indicators for patients undergoing total hip arthroplasty, dependent on their BMI levels.
