Preoperative Symptoms in Femoroacetabular Impingement Patients Are More Related to Mental Health Scores Than the Severity of Labral Tear or Magnitude of Bony Deformity.

BACKGROUND: The purpose of this study was to determine the relationships between patient factors, mental health status, the condition of the local tissue, magnitude of bony deformity, and preoperative symptoms in a series of femoroacetabular impingement (FAI) patients.
METHODS: From our prospective outcomes registry, we identified 64 patients with arthroscopically-treated labral tears and cam deformities. We assessed the correlations between patient factors (age, sex, body mass index, level of education), surgical findings (size of labral tear, presence of chondral lesions), mental health factors (VR-12 mental component score [MCS], depression, and preoperative use of psychotropic and/or opioid drugs), magnitude of FAI deformity (alpha and lateral center edge angles), and preoperative hip dysfunction and osteoarthritis outcome score (HOOS) subscales. Patient factors, surgical and radiographic findings, and preoperative HOOS scores were compared between patients with low and high MCS.
RESULTS: Neither hip pathology nor patient-related factors significantly correlated with HOOS scores. On the contrary, MCS significantly correlated with HOOS symptom (ρ = 0.45, P < .001) and pain scores (ρ = 0.52, P < .001). Low MCS patients had significantly lower preoperative scores for all 5 HOOS subscales (P ≤ .002) and more frequent chondral lesions and comorbid depression (P ≤ .01).
CONCLUSION: Symptom severity was significantly more related to mental health status than either the size of labral tear or FAI deformity. Patients with low MCS had significantly worse preoperative pain and self-reported function, and a greater prevalence of concomitant chondral lesions. Future studies are necessary to determine if earlier surgical treatment or preoperative psychological and/or pain coping interventions may improve outcomes for those with low MCS.
