The changes in psychologic measures and symptoms of depression, anxiety, and pain catastrophizing following periacetabular osteotomy (PAO) are not well studied. This study aims to fill this knowledge gap by addressing the question: Do patients with acetabular dysplasia have significant improvement in psychological outcome scores after PAO? We reviewed 52 hips (48 patients) treated with PAO for acetabular dysplasia from February 2017 to July 2020 using Depression, Anxiety, and Stress Scale – 21 (DASS21), Hospital Anxiety and Depression Scale (HADS), Pain Catastrophizing Scale (PCS), radiographic analysis, and pain location/severity questionnaires. Descriptive statistics and a mixed effects model were used to test the difference in patient-reported outcome measures from before and after surgery with adjustment for age, body mass index, follow-up duration, previous hip surgery, and concurrent surgery while also accounting for clustered data. There was a statistically significant difference between preoperative and postoperative outcome scores for all three measures used in this study (DASS21 p = 3.22E-09; HADS p = 2.82E-10, PCS p = 2.12E-09). These results indicate that patients with acetabular dysplasia might expect significant improvement in symptoms of depression, anxiety, and pain catastrophizing following PAO.
