  • Title: Mental health and outcomes in primary total joint arthroplasty.
    Author: Lavernia CJ, Alcerro JC, Brooks LG, Rossi MD.
    Journal: J Arthroplasty; 2012 Aug; 27(7):1276-82. PubMed ID: 22226610.
    Abstract:
    A consecutive series of 640 total joint arthroplasty patients was interviewed before surgery and at a minimum of 2 years following surgery. Statistical analyses were conducted to examine the effect of psychological distress and other patient characteristics on outcomes (Western Ontario and McMaster Universities Osteoarthritis Index, Short Form 36, and Quality of Well-Being index). Before and after surgery, distressed subjects had significantly lower scores than nondistressed subjects for most dependent measures (P range, .05 ≤ .001). All mean outcomes improved by follow-up in both groups (P ≤ .001) except mental health scores of nondistressed subjects. Stepwise regression analysis found that low baseline mental health score, non-Hispanic ethnicity, and fewer years since procedure were the strongest predictors of worse Western Ontario and McMaster Universities Osteoarthritis Index scores at follow-up. Although the magnitude of improvement is similar to nondistressed subjects, distressed patients do not achieve comparable functional and psychosocial outcomes.
