Objectives:   The purpose of the study was to investigate the association between preoperative opioid use and persistent postoperative use, and determine the impact of preoperative opioid use on patient reported outcomes (PROs) in patients undergoing patellofemoral stabilization surgery.Methods:   A retrospective analysis of 60 patients after patellofemoral stabilization surgery with a minimum of 2-year follow-up was performed using a prospectively-collected patellar instability registry. Patients were categorized as opioid naïve (n=48) or preoperative opioid users (n=12). Postoperative opioid use was assessed for all patients at 2 and 6 weeks. Knee Injury and Osteoarthritis Outcome Score (KOOS) and Kujala questionnaires were administered at baseline, and 6 months and 2 years postoperatively.Results:   Preoperative opioid use was identified as an independent risk factor for postoperative opioid use at 2- and 6-weeks following surgery (p=0.0023 and p&lt;0.0001, respectively). Preoperative opioid use was associated with significantly lower KOOS and Kujala scores at baseline, 6 months and 2 years postoperatively. Both groups significantly improved from baseline KOOS and Kujala scores at 6 months and 2 years postoperatively. Regardless of preoperative opioid use, opioid use at 6 weeks after surgery was associated with worse KOOS scores at 6 months and 2 years postoperatively.Conclusion:   In patients undergoing patellofemoral stabilization surgery, preoperative opioid use was predictive of postoperative use. Additionally, preoperative opioid use was associated with worse PROs at 6 months and 2 years following surgery. [Table: see text][Table: see text]
