Bariatric Surgery Prior to Total Joint Arthroplasty May Not Provide Dramatic Improvements in Post-Arthroplasty Surgical Outcomes

摘要

Obesity (body mass index (BMI) > 30 kg/m2) occurs in 34% [1] of the general United States population. Obesity is the second leading cause of death in this country [2], the leading cause of overall health burden [3], and also a risk factor and moderator in the development of other health conditions. An estimated 55% of patients undergoing total knee arthroplasty (TKA) [4] and 39% of patients undergoing total hip arthroplasty (THA) [5] in the United States are obese. Obesity is associated with higher complication rates (e.g. surgical site infection (SSI), dislocations, and readmissions) [6,7] in patients undergoing total joint arthroplasty (TJA).
