Obesity, Bariatric Surgery, and Hip/Knee Arthroplasty Outcomes

Katelyn M Mellion et al. Surg Clin North Am. 2021 Apr.

Abstract

Obesity is an independent risk factor for osteoarthritis due to mechanical and inflammatory factors. The gold-standard treatment of end-stage knee and hip osteoarthritis is total joint arthroplasty (TJA). Weight loss decreases progression of osteoarthritis and complications following TJA in patients with obesity. Bariatric surgery allows significant, sustained weight loss and comorbidity resolution in patients with morbid obesity. Existing data describing bariatric surgery on TJA outcomes are limited but suggest a benefit to bariatric surgery prior to TJA. Further studies are needed to determine optimal risk stratification, bariatric procedure selection, and timing of bariatric surgery relative to TJA.

Keywords: Arthroplasty; Bariatric surgery; Lower extremity osteoarthritis; Outcomes.
