The Psychology of ACL Injury, Treatment, and Recovery: Current Concepts and Future Directions.
Review
Overview
abstract
CONTEXT: Interest in the relationship between psychology and the outcomes of anterior cruciate ligament (ACL) reconstruction (ACLR) continues to grow as variable rates of return to preinjury level of activity continue to be observed. EVIDENCE ACQUISITION: Articles were collected from peer-reviewed sources available on PubMed using a combination of search terms, including psychology, resilience, mental health, recovery, and anterior cruciate ligament reconstruction. Further evaluation of the included bibliographies were used to expand the evidence. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: General mental health and wellbeing, in addition to a host of unique psychological traits (self-efficacy, resilience, psychological readiness and distress, pain catastrophizing, locus of control, and kinesiophobia) have been demonstrated convincingly to affect treatment outcomes. Moreover, compelling evidence suggests that a number of these traits may be modifiable. Although the effect of resilience on outcomes of orthopaedic surgical procedures has been studied extensively, there is very limited information linking this unique psychological trait to the outcomes of ACLR. Similarly, the available information related to other parameters, such as pain catastrophizing, is limited with respect to the existence of adequately sized cohorts capable of accommodating more rigorous and compelling analyses. A better understanding of the specific mechanisms through which psychological traits influence outcomes can inform future interventions intended to improve rates of return to preinjury level of activity after ACLR. CONCLUSION: The impact of psychology on patients' responses to ACL injury and treatment represents a promising avenue for improving low rates of return to preinjury activity levels among certain cohorts. Future research into these areas should focus on specific effects of targeted interventions on known, modifiable risk factors that commonly contribute to suboptimal clinical outcomes. STRENGTH-OF-RECOMMENDATION TAXONOMY (SORT): B.
