ACL Reconstruction Rehabilitation With Exercise and Psychological Support

The objective of this study is to examine the efficacy of Rehabilitation with Exercise and Psychological Support (REPS), a rehabilitation approach that integrates exercise with psychological support provided by physical therapist and patient training videos. The central hypothesis is that REPS will facilitate better psychological response (Specific Aim 1) and knee function (Specific Aim 2) than Standard Rehabilitation after ACL reconstruction. The feasibility, acceptability, and fidelity of implementing REPS will be explored. This is a pilot randomized controlled trial of 60 patients with ACL reconstruction who receive REPS or Standard Rehabilitation. Study participants in both treatment arms will receive exercise per a standard rehabilitation protocol. Physical therapists providing the REPS intervention will receive didactic training in psychologically informed practice principles and REPS procedures, clinical application practice, and regular feedback from the study team. Study participants in REPS will receive training videos on psychosocial aspects of recovery and mental skills to improve the psychological response. Study visits will occur prior to surgery (baseline), immediately before the first rehabilitation visit post-surgery, 3 months post-surgery, and 6 months post-surgery.

Study Aims Specific Aim 1. To examine the efficacy of REPS on psychological response after ACL reconstruction. Primary Hypothesis: Psychological readiness for sport, measured with the ACL Return to Sport after Injury (ACL-RSI) scale, will be higher in REPS than Standard Rehabilitation at 6 months post-surgery. Secondary Hypothesis: Kinesiophobia, measured with the Tampa Scale for Kinesiophobia (TSK-11) questionnaire, will be lower in REPS than Standard Rehabilitation at 6 months post-surgery.

Specific Aim 2. To examine the efficacy of REPS on knee function after ACL reconstruction. Hypothesis: Self-reported knee function, measured with the International Knee Documentation Committee (IKDC) subjective form, will be higher in REPS than Standard Rehabilitation at 6 months post-surgery.

Exploratory Aim. To assess the feasibility, acceptability, and fidelity of implementing REPS after ACL reconstruction. Research records will be used to assess the feasibility of REPS, and develop surveys for patients and clinicians will be used to assess the acceptability of REPS. In both treatment arms, patients will complete questionnaires that align with anticipated clinical changes in empathy (Consultation and Relational Empathy, CARE) and therapeutic alliance (Working Alliance Inventory-Short Revised, WAI-SR), and documentation templates will be used to record treatments and training for descriptive analysis of fidelity.
