The Influence of Psychosocial Factors on Hip Surgical Disorders and Outcomes After Hip Arthroscopy: A Systematic Review.

<bold>Purpose: </bold>To systematically review the associations between mental health and preoperative or postoperative outcomes of hip arthroscopy for femoroacetabular impingement.<bold>Methods: </bold>The literature search was conducted using the PubMed, EMBASE and PsychINFO databases following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines.<bold>Results: </bold>Nine studies were identified that met the inclusion and exclusion criteria. All studies assessing patient-reported outcomes found significantly lower patient-reported outcomes (modified Harris Hip Score, Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports-Specific Subscale, and International Hip Outcome Tool scores) related to worse mental health functioning before surgery. Specifically, preoperative Hip Outcome Score-Activities of Daily Living and Hip Outcome Score-Sports-Specific Subscale were significantly greater in control patients than patients in the mental health group by 11.6 points (mean difference; 95% confidence interval 7.58-15.79, P < .001) and 10 points (95% confidence interval 5.14-14.87, P < .001), without significant heterogeneity between studies (I2 = 28.59, P = .25; I2 = 0, P = .93), respectively. Patients with lower mental health status also had lower rates of achieving a minimal clinically important difference in 5 studies included in this review.<bold>Conclusions: </bold>This systematic review finds consistent evidence supporting the association between negative psychological function and worse preoperative and postoperative outcomes for patients with hip disorders. Understanding both the effect of mental health on surgical outcomes and the potential benefits of psychological intervention may represent an opportunity to improve patient outcomes following hip arthroscopy.<bold>Level Of Evidence: </bold>IV, systematic review of Level II-IV studies.
