Two-year outcomes in primary THA in obese male veterans administration medical center patients

摘要

The objective of this study was to examine the influence of obesity on the rate of infection, dislocation, and overall complications in a group of male patients undergoing primary total hip arthroplasty (THA). The study involved a retrospective review of the association of body mass index (BMI) and dislocation, infection, and complications on 255 consecutive male patients who received a THA. BMI of 40 and greater had significantly more dislocations and approached significance for infections. The present study suggests that the risk of infection and dislocation increases only in highly obese males (BMI > 40) in contrast to other studies that have reported a higher risk infection, dislocation, and complications with a BMI of obesity in females (BMI > 30).
