Hartford JM, et al. - This research was intended to correlate the 90-day perioperative complication rate of total hip arthroplasty conducted through the direct anterior approach stratified by BMI. Researchers distinguished perioperative complications both intraoperative and up to 90 days postoperative in a case series of 1,808 primary total hip arthroplasties conducted through a direct anterior approach. According to BMI, patients were stratified. They reported demographics of age, side, gender, and American Society of Anesthesiologists score. They recorded medical and surgical complications including National Surgical Quality Improvement Program complications, length of stay, reoperation rate, readmission rate, and length of operation. They conducted Bivariate analysis and analysis of variance. A greater rate of surgical complications both in number and in severity occurs with the morbidly obese undergoing total hip arthroplasty through a direct anterior approach in stratifying patients undergoing the direct anterior technique for total hip arthroplasty by BMI.
