Abstract

Background: Total knee arthroplasty (TKA) is one of the most common operating room procedures performed in the United States and has been increasing over the past decade as the population continues to age. The incidence of chronic obstructive pulmonary disease (COPD) in the aging population has been steadily increasing as well. As a result, a larger percentage of patients who undergo TKA have COPD. In this study we assessed the following: (1) What demographics and comorbidities are most likely to present concurrently in patients with COPD? (2) Are patients with COPD undergoing TKA at increased risk for development of postoperative complications within 30 days? (3) Do patients with COPD have a higher propensity for extended hospital stay or unplanned return to operating room? (4) Does COPD act as an independent risk factor for development of postoperative complications within 30 days?

Methods: A retrospective cohort study was conducted utilizing data collected via the American College of Surgeons National Quality Improvement Program Database. Patients who underwent primary TKA from 2005 to 2014 were included in this study. Complications were classified into operative, directly related to surgical procedure, and non-operative, indirectly related to surgical procedure. Univariate and multivariate analyses were conducted on appropriate data.

Results: COPD was an independent risk factor for complications including deep surgical site infections (DSSI), pneumonia, re-intubation, failure to wean > 48 hours, progressive renal insufficiency, acute renal failure and cardiac arrest requiring resuscitation. Patients with COPD were additionally found to have longer hospital stays and non-home discharge.
