The Relationship Between Preoperative Opioid Use and Adverse Events Following Total Knee Arthroplasty


This study aims to compare perioperative events following total knee arthroplasty (TKA) amongst various degrees of preoperative opioid use. In total, 84,569 patients undergoing TKA were identified from a Humana Claims Dataset, and stratified by their preoperative opioid use based on number of prescriptions filled within 6 months of surgery (naïve 0 [50,561]; sporadic 1 [12,411]; chronic 2 or greater [21,687]). Outcomes of interest included Center for Medicare and Medicaid Services (CMS)-reportable complications, need for postoperative supplemental oxygen, 90-day readmission, and hospital length of stay. Complication rates (9.8% vs 8.9% vs 12.6%; p < 0.01), need for supplemental oxygen (3.0% vs 3.1% vs 5.3%; p = 0.03), mean length of stay (2.1 vs 2.8 vs 3.5; p < 0.01), and 90-day readmission (9.7% vs 10.8% vs 16.4%; p < 0.01) significantly differed amongst groups. On logistic regression, only the chronic opioid use group was associated with significantly increased likelihood of complications, need for supplemental oxygen, and readmission.
