The obesity crisis in the United States has caused a significant increase of hip arthritis. Surgical complication rates are higher in this population and guidelines are being used to select patients who are acceptable candidates for surgical intervention. This retrospective study evaluated the complication rates for obese patients undergoing total hip replacement compared to non-obese patients as defined by the World Health Organization (WHO). Additionally, we compared complication rates of the direct anterior approach (ATHA) versus the posterior approach (PTHA) in a consecutive group of patients using similar protocols. This study is an IRB approved retrospective review of 210 patients undergoing ATHA and 201 patients undergoing PTHA during the same time period by 2 experienced, high-volume total joint surgeons. Non-obese patients were compared to obese patients using WHO body mass index (BMI) classification. Minor and major complications were reviewed as well as surgical time, length of stay, disposition, and short-term outcome measures (including pain scores, narcotic use, and assistive device use).BACKGROUND
