OP3.5 Does Patient Resiliency Influence Patient-reported outcomes at Presentation in Symptomatic Femoroacetabular Impingement

Background: Resilience, quantified by the brief resilience scale (BRS), has been recognized for its role in pain and symptomatology in musculoskeletal conditions. The role of psychological factors in the clinical presentation and outcomes of FAI surgery continues to be poorly understood.

Methods: This is a prospective multicenter study of FAI patients undergoing primary hip arthroscopy. PROMs were administered at baseline, 3-, and 6-months post-op and included the Patient Reported Outcomes Measurement Information System (PROMIS) domains of anxiety and depression, as well as Hip Disability and Osteoarthritis and Outcome Score (HOOS), modified Harris Hip Score (mHHS), and International Hip Outcome Tool (iHOT-12). Resilience was characterized by BRS score and divided into low (“L”, score<3), normal (“N”, score 3-4.3), and high resilience (“H”, score>4.3).

Results: 675 patients were included with a mean age of 24.9±7.8 years and female predominance (56%). Mean BRS scores were 3.7±0.7 (1.5-5.0). 13.8% (n=93) had low resilience, 65.9% (n=445) had normal resilience, and 20.3% (n=137) had high resilience. Lower resilience had more severe symptoms in HOOS pain (p<0.001), HOOS sports (p=0.003), HOOS ADL (p<0.001), HOOS QoL (p<0.001), iHOT-12 (p=0.002), and mHHS (p<0.001). Anxiety (L: 50.5%/N: 14.4%/H: 2.2%) and depression (L: 38.7%/N: 8.8%/H: 2.9%) were higher in lower resilience groups (all p<0.001) and this trend stayed consistent in female and male sub-analyses with females having greater anxiety and depression symptoms. The follow-up cohort with 3- and 6-months follow-up was 487 patients and had similar baseline characteristics as the baseline cohort. Lower resilience had lower postoperative PROs (with similar change) (p<0.05). After treatment, rates of anxiety or depression decreased from 22.1% to 15.6% with the low resilience group having the highest change from 62.9% to 45.9%.

Conclusion: Low resilience correlates with more severe symptoms and predicts anxiety/depression in FAI. 13.8% had low resilience while 20.3% had high resilience. Lower resilience had worse postoperative PROs. Particularly in patients with low resilience at presentation, rates of anxiety or depression symptoms decreased postoperatively. Further studies are needed to understand the role of resilience in longer-term outcomes of FAI and whether concurrent psychological treatment will help improve patient outcomes after hip arthroscopy for FAI.
