Hartford JM, et al. - This study was sought to compare 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, the patients were stratified. They recorded demographics of age, side, sex and ASA score. They further noted Medical and Surgical complications including National Surgical Quality Improvement complications, length of stay, reoperation rate, readmission rate and length of operation. Bivariate analysis and analysis of variance were conducted. Results reveal a greater rate of surgical complications both number and severity occur with the morbidly obese undergoing total hip arthroplasty through a direct anterior method in stratifying patients undergoing the direct anterior approach for total hip replacement by BMI.
