Impact of BMI on Complications, Readmissions, and Perioperative Metrics in a Mature Direct Anterior Approach Total Hip Arthroplasty (THA) Practice

Year: 2025

Type: article

Abstract: This study analyzed complication rates, perioperative metrics, and hospital readmissions across BMI cohorts in patients undergoing direct anterior approach (DAA) total hip arthroplasty (THA) in a mature hip practice. Currently, the precise BMI cutoff points for risk in THA are not fully understood. A retrospective review was conducted of patients who underwent DAA THA by a single, highly experienced, fellowship-trained surgeon between January 2021 and January 2023. The use of single-surgeon cases allows for control of many potentially confounding variables but may limit the generalizability of the findings. Data collected included patient demographics, hospital readmissions, 12-month complication rates, and intraoperative metrics. Patients with Class II obesity (BMI 35–39.9) kg/m2 and Class I obesity (BMI 30–34.9) kg/m2 had significantly higher intraoperative blood loss and longer operative times compared to the control group (BMI 20–24.9 kg/m2). No statistically significant differences in hospital readmission rates or complication rates were observed between BMI cohorts. Higher BMI was associated with increased intraoperative blood loss and longer operation time; however, no differences were found in hospital readmissions or complication rates between BMI cohorts.
