High Body Mass Index is Related to Increased Perioperative Complications After Periacetabular Osteotomy.
The purpose of this study is to determine the relationship of body mass index (BMI), age, smoking status, and other comorbid conditions to the rate and type of complications occurring in the perioperative period following periacetabular osteotomy. A retrospective review was performed on 80 hips to determine demographic information as well as pre- and postoperative pain scores, center-edge angle, Tönnis angle, intraoperative blood loss, and perioperative complications within 90 days of surgery. Patients were placed into high- (>30) and low- (<30) BMI groups to determine any correlation between complications and BMI. The high-BMI group had a significantly greater rate of perioperative complications than the low-BMI group (30% vs 8%) and, correspondingly, patients with complications had significantly higher BMI than those without (30.9 ± 9.5, 26.2 ± 5.6) (P = .03). Center-edge angle and Tönnis angle were corrected in both groups. Improvement in postoperative pain scores and radiographically measured acetabular correction can be achieved in high- and low-BMI patients. High-BMI patients have a higher rate of perioperative wound complications.
