Opioid Use Following Primary Unilateral Total Knee Arthroplasty Varies With Age

Abstract Background: Reducing unused prescribed opioids following arthroplasty procedures remains a challenge. The relationship between opioid consumption and age has seldom been investigated. We hypothesize that older patients consume fewer narcotic medications than younger patients following primary unilateral total knee arthroplasty (TKA).

Patients were stratified by age at the time of operation (40-49, 50-59, 60-69, 70-79, 80+). Narcotic medications used in-house and in the 3 months following
