Purpose
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 < 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.
