The prevalence of obesity in the general population is increasing. Obesity is estimated to affect approximately one-third of adults in the United States. It is estimated that 6.1 million patients who undergo total joint arthroplasty will be obese by 2040.
It is a known fact that obese patients undergoing total joint arthroplasty (TJA) are at higher risk of all complications in general, particularly infection. An increased risk for wound healing, infection, anemia, acute renal insufficiency, respiratory failure and urinary tract infection have been linked to obesity in patients undergoing TJA. Multiple studies have shown obesity can negatively impact the technical performance of both total hip arthroplasty (THA) and total knee arthroplasty (TKA), as well as influence the implant survivorship.
