Abstract
Background
This study aimed to determine the impact of preoperative opioid use on outcomes of patients undergoing ankle or hindfoot arthrodesis, or total ankle arthroplasty (TAA).
Methods
We conducted a retrospective review of 190 patients undergoing an ankle or hindfoot arthrodesis (n=122) or TAA (n=68) between December 2015 and September 2020 with a single fellowship-trained orthopaedic foot and ankle surgeon at an academic medical center. Data collected included demographics, medical comorbidities, treatment history, complications and reoperation rates, patient-reported outcome measures (PROMs) (eg, Foot and Ankle Outcome Score [FAOS]), and opioid use.
Results
Patients with preoperative opioid use were more likely to continue usage at 90 (r = 0.931, P < .001) and 180 (r = 0.940, P < .001) days postoperatively. For the entire cohort, complication and reoperation rates were 48.9% and 13.2%, respectively. While preoperative opioid use groups did not differ in the overall complication rate, users had significantly more infections (user = 12.5%, nonuser = 3.3%; P = .036) and reoperations (user = 22.5%, nonuser = 10.7%; P = .049). When analyzing postoperative opioid prescriptions, there were many significant correlations with preoperative PROMs, mainly FAOS, such that increased postoperative opioid use was associated with worse subjective outcomes.
Conclusion
Preoperative opioid users are more likely to continue postoperative opioid use, experience infections, and undergo reoperations.
