Psychosocial factors and surgical outcomes: an evidence-based literature review.
ABSTRACT The influence of psychosocial factors on clinical outcomes after surgery has been investigated in several studies. This review is limited to surgical outcomes studies published between 1990 and 2004 that include (1) psychosocial variables (eg, depression, social support) as predictors of outcome and that focus on (2) clinical outcomes (eg, postoperative pain, functional recovery) using (3) specific multivariate analytic techniques with (4) relevant clinical variables (eg, presurgical health status) included as covariates. Twenty-nine studies met these criteria. Results indicate that psychosocial factors play a significant role in recovery and are predictive of surgical outcome, even after accounting for known clinical factors. Attitudinal and mood factors were strongly predictive; personality factors were least predictive. The results suggest that preoperative consideration of attitudinal and mood factors will assist the surgeon in estimating both the speed and extent of postoperative recovery.

ABSTRACT: Psychological distress has been associated with inferior scores for pain after total knee arthroplasty (TKA). However, its relationships with scores and arthrofibrosis after TKA remain unclear.Clinical Orthopaedics and Related Research 07/2014; 473(1). DOI:10.1007/s11999-014-3769-5 · 2.88 Impact Factor

ABSTRACT: Background Psychological perceptions are increasingly being recognized as important to recovery and rehabilitation post-surgery. This research longitudinally examined perceptions of the personal importance of exercise and fears of re-injury over a three-year period post anterior cruciate ligament (ACL) reconstruction. Stability and change in psychological perceptions was examined, as well as the association of perceptions with time spent in different types of physical activity, including walking, household activities, and lower and higher risk for knee injury activities. Methods Participants were athletes, 18–40 years old, who underwent ACL reconstruction for first-time ACL injuries. They were recruited from a tertiary care centre in Toronto, Canada. Participants completed interviewer-administered questionnaires pre-surgery and at years one, two and three, postoperatively. Questions assessed demographics, pain, functional limitations, perceived personal importance of exercise, fear of re-injury and physical activities (i.e., walking; household activities; lower risk for knee injury activities; higher risk for knee injury activities). Analyses included fixed-effect longitudinal modeling to examine the association of a fear of re-injury and perceived personal importance of exercise and changes in these perceptions with the total hours spent in the different categories of physical activities, controlling for other factors. Results Baseline participants were 77 men and 44 women (mean age = 27.6 years; SD = 6.2). At year three, 78.5% of participants remained in the study with complete data. Fears of re-injury decreased over time while personal importance of exercise remained relatively stable. Time spent in walking and household activities did not significantly change with ACL injury or surgery. Time spent in lower and higher risk of knee injury physical activity did not return to pre-injury levels at three years, post-surgery. Greater time spent in higher risk of knee injury activities was predicted by decreases in fears of re-injury and by greater personal importance of exercise. Conclusions This study highlights not only fears of re-injury, which has been documented in previous studies, but also the perceived personal importance of exercise in predicting activity levels following ACL reconstructive surgery. The findings can help in developing interventions to aid individuals make decisions about physical activities post knee injury and surgery.01/2015; 7. DOI:10.1186/2052-1847-7-4
