Epidemiologic trends and recent literature reports indicate that the combination of bariatric surgery as a first step followed by orthopedic interventions as a second stage is beneficial for our patients. Bariatric interventions have proven to be safe and efficacious, offering a bridge to patients affected by severe obesity and osteoarthritis to undergoing a successful and long-lasting joint arthroplasty. In addition, the combination of joint arthroplasty after bariatric interventions will help patients resume their normal activities while introducing lifestyle changes that will, in turn, enable them to maintain weight loss.
