Background: Pain in the immediate postoperative period following total joint arthroplasty is influenced by various patient factors, including major depressive disorder (MDD). Therefore, this study aimed to compare the patient perception of pain and opioid consumption between patients with and without MDD who received either a total knee arthroplasty (TKA) or total hip arthroplasty (THA). Specifically, we compared (1) pain intensity, (2) lengths of stay, (3) opioid consumption, and (4) patient perception of pain control.
Methods: We reviewed our institutional Press Ganey database to identify patients with a diagnosis of MDD who received a THA (n = 48) and TKA (n = 68) between 2012 and 2016. An independent samples t-test and chi-square analyses were conducted to assess continuous and categorical variables, respectively. Analysis of covariance assessed the effects of depression on postoperative pain intensity. Mixed-design analysis of variance assessed the difference in opioid consumption between groups.
Results: Patients with MDD who received THA or TKA demonstrated a higher mean pain intensity score when compared to those without MDD; however, this was not statistically different (235.6 vs 207.7; P = .264 and 214.8 vs 185.1; P = .055, respectively). Patients with MDD who received THA or TKA consumed more opioids when compared to those without MDD (P = .048 and P = .038, respectively).
Conclusion: Patients with MDD undergoing total joint arthroplasty consume more opioids compared to their matched cohort during the immediate postoperative period. Identifying patient-specific factors, such as MDD, could help arthroplasty surgeons modulate patients' course of recovery. These findings warrant more cooperation between arthroplasty surgeons and primary care providers to optimize outcome.
