Cost-Effectiveness of Bariatric Surgery Prior to Total Knee Arthroplasty in the Morbidly Obese A Computer Model-Based Evaluation

摘要

Background: Obesity is associated with adverse outcomes and increased costs after total knee arthroplasty. Bariatric surgery is an effective treatment for morbid obesity, but its cost-effectiveness for weight loss prior to total knee arthroplasty is unknown. The purpose of this study was to evaluate the cost-effectiveness of bariatric surgery prior to total knee arthroplasty for patients in whom medical treatment of obesity and knee osteoarthritis had failed.
