Abstract

This study compared the total joint arthroplasty (TJA) surgical outcomes of patients who had bariatric surgery prior to TJA to TJA patients who were candidates but did not have bariatric surgery. Patients were retrospectively grouped into: Group 1 (n = 69), those with bariatric surgery >2 years prior to TJA, Group 2 (n = 102), those with surgery within 2 years of TJA, and Group 3 (n = 11,032), those without bariatric surgery. In Group 1, 2.9% (95% CI 0.0-6.9%) had complications within 1 year compared to 5.9% (95% CI 1.3%-10.4%) in Group 2, and 4.1% (95% CI 3.8%-4.5%) in Group 3. Ninety-day readmission (7.2%, 95% CI 1.1%-13.4%) and revision density (3.4/100 years of observation) was highest in Group 1. Bariatric surgery prior to TJA may not provide dramatic improvements in post-operative TJA surgical outcomes.

Keywords: bariatric surgery; complications; joint arthroplasty; obesity; revision; surgical site infection.
