Popis: BACKGROUND: The aim of our study was to evaluate whether an association exists between body mass index (BMI) category and post-operative opioid requirements among primary total joint arthroplasty (TJA) patients. METHODS: We retrospectively reviewed all primary unilateral total hip and total knee arthroplasty (THA/TKA, respectively) cases performed over a two-year period. We evaluated whether a relationship exists between five BMI categories (≤24.9, 25–29.9, 30–34.9, 35–39.9, ≥40) and morphine milligram equivalent (MME) use for total in-hospital, daily in-hospital, and total during six weeks post-discharge. Secondary outcomes included relationship with length of stay, discharge location, opioid refill rate, and pre-operative opioid usage. RESULTS: For all patients undergoing primary TJA, increasing BMI resulted in an incremental increase in post-operative total in-hospital MME use for each successive BMI category when compared to those with BMI ≤24.9 (p
