What Are Our Patients Really Telling Us? Psychological Constructs Associated With Patient-Reported Outcomes After Anterior Cruciate Ligament Reconstruction
Context Depressed patient-reported outcomes (PROs) are directly related to suboptimal recovery after anterior cruciate ligament reconstruction (ACLR). Various PROs commonly used after ACLR can provide a gross estimation of function but do not fully elucidate the causes of self-perceived disability. Objective To more fully characterize the factors driving responses on PROs. Design Cross-sectional study. A mixed-methods approach was used, in which qualitative interviews were conducted alongside administration of PROs to uncover the themes behind a participant's PRO responses. Setting Laboratory. Patients or Other Participants Twenty-one individuals with unilateral ACLR (age = 20.90 ± 2.86 years, height = 172.0 ± 11.03 cm; mass = 71.52 ± 13.59 kg, postsurgery = 3.66 ± 3.03 years). Main Outcome Measure(s) Patient-reported outcome measures were administered and qualitative interviews were conducted. The PROs consisted of the International Knee Documentation Committee form, Knee Injury and Osteoarthritis Outcomes Score (KOOS), ACL-Return to Sport after Injury (ACL-RSI) scale, and Tampa Scale of Kinesiophobia (TSK). A hierarchical cluster analysis was used to identify subgroups based on PRO responses. Qualitative interviews provided supplemental insight into perceived disability. Independent t tests examined cluster differences for themes. Spearman ρ correlations indicated associations between PRO responses and themes. Results Two clusters (perceived high or low disability) emerged. Individuals with low perceived disability scored better on all PROs (P .05) except for the KOOS-Activities of Daily Living. Internal and external facilitators or barrier subthemes emerged from the interviews. A significant difference was present between clusters and themes. Lower TSK andgreater ACL-RSI and KOOS-Quality of Life scores were associated with more perceived facilitators. Conclusions Participants with greater internal motivation and confidence and a support network had improved PROs. Those with avoidance tendencies, fear, lack of clear expectations, and less social support scored worse on PROs. The TSK, ACL-RSI, and KOOS-Quality of Life scales were best able to capture the constructs associated with perceived wellness, which reinforces their utility in recovery.
