Abstract
INTRODUCTION
The aim of this study was to assess whether PTSD was associated with preoperative and/or postoperative joint-specific function and health-related quality of life (HRQoL) in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) and whether there were associated preoperative factors.
METHODS
A retrospective study was conducted at a single centre using an established arthroplasty database over a 2-year period. Patients undergoing THA and TKA completed pre and 1-year postoperative Oxford hip/knee scores and EuroQoL questionnaire (EQ-5D) to assess joint specific function and HRQoL. Postoperatively, patients completed the self-reported PTSD Checklist for DSM-5 (PCL-5) questionnaire where a score of 31 or greater was used to determine a provisional diagnosis of PTSD.
RESULTS
There were 1244 THA and 1356 TKA patients, of which 42 (3.4%) and 54 (4.0%) had a PCL-5 score of ≥ 31, respectively (PTSD groups). Younger age was associated (p < 0.001) with PTSD for both THA (mean difference (MD) 9.9, 95%CI 6.7-13.0) and TKA (MD 4.6, 95%CI 2.2-6.9), which remained significant when adjusting for confounding variables (THA: p < 0.001; TKA: p = 0.020). The preoperative Oxford (THA:MD 4.9, p < 0.001; TKA:MD 5.7, p < 0.001) and EQ-5D scores (THA:MD 0.378, p < 0.001; TKA:MD 0.276, p < 0.001) were significantly worse in the PTSD groups. Age (AUC 73.8%, p < 0.001) and EQ-5D (AUC 72.9%, p < 0.001) were independent factors that were predictive of PTSD in patients undergoing THA and TKA, respectively. When adjusting for confounding variables, PTSD was clinically and statistically significantly (p < 0.001) associated with a lower improvement in the Oxford (THA:MD 9.3; TKA:MD 10.0) and EQ-5D (THA:MD 0.375; TKA:MD 0.293) scores.
CONCLUSIONS
One in 25 patients met a provisional PTSD diagnosis; they were younger and had worse preoperative and improvement in postoperative joint specific function and HRQoL. Age and EQ-5D could be used to identify patients at risk.
