Anterior cruciate ligament (ACL) surgery patients experience physical trauma, both in the physical injury itself and following surgery, and face potential long-lasting adverse effects such as muscle weakness, diminished joint function, hip pain, and fear. Many of these patients report more significant anxiety and depression following surgery, which can further compound these patients' adverse outcomes. This study is a single-blind, randomized controlled trial design to evaluate the effects of a remotely-delivered 8-week mindfulness intervention on patient-reported outcomes (PROs) following ACL reconstruction surgery.
Rationale and Approach: ACL reconstruction surgery patients experience physical trauma, both in the physical injury itself and following surgery, and face potential adverse long-lasting effects such as muscle weakness, arthritis, persistent knee pain, anxiety, depression, post-traumatic stress, and fear of re-injury. Many of these patients report sufficient psychological trauma that undermines a return to sport and potentially contributes to the risk of re-injury to the repaired knee. This study is a single-blind, randomized controlled trial design to evaluate the effects of a remotely-delivered 8-week mindfulness intervention on patient-reported outcomes following ACL reconstruction surgery.
Specific Aim 1: To determine the influence of mindfulness training on patient-reported outcomes and return to sport following ACL reconstruction surgery
Specific Aim 2: To determine the influence of mindfulness training on re-injury risk following ACL reconstruction surgery
Specific Aim 3: To determine the factors that influence mindfulness efficacy in patient-reported outcomes and return to sport following ACL reconstruction surgery

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Mindfulness Intervention plus Standard of Care | Experimental | The Foundations and Awareness modules of the HMP app require a minimum of 133 and 253 minutes, equating to less than 5 and less than 10 minutes per day on average, respectively. Date, duration, and content of usage will be recorded for each participant through the app. Participants will have access to the entire contents of the app for the full duration of the study. |

| Standard of Care | No Intervention | Control group receives standard of care only |

|---|---|---|---|---|
| Healthy Minds Program (HMP) App | Behavioral | The full HMP app includes 5 modules with practices designed to cultivate categories of mental and emotional skills linked to both hedonic and eudaimonic well-being. These include the cultivation of mindful attention (Awareness), positive relationships with self and others (Connection), insight into the nature of self and internal experience (Insight), and purpose, values, and meaning in life (Purpose), as well as an initial module which includes abbreviated introductions to the topics and lessons in all four areas (Foundations). For this study, the active intervention will include 4 weeks of training using the Foundations module followed by 4 weeks of training using the Awareness module. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in PROMIS Global Health Questionnaire (GHQ) Score | Global quality of life (QoL) will be assessed via a 9-item questionnaire scored on a 0-100 scale where higher scores indicate better QoL, pain interference, and fatigue. | baseline, 6 weeks, 3 months, 6 months, 12 months, 24 months post surgery |
| Change in PROMIS Anxiety Questionnaire Score | Anxiety will be assessed via an 8-item questionnaire scored from 0-5 where higher scores represents greater anxiety. | baseline, 6 weeks, 3 months, 6 months, 12 months, 24 months post surgery |

| Change in Single Assessment Numeric Evaluation (SANE) Score | Pain severity is assessed via a single item survey scored from 0-100 where a higher score indicates greater pain. | baseline, 6 weeks, 3 months, 6 months, 12 months, 24 months post surgery |
| Change in Horowitz Impact of Events Scale Score | Post-traumatic stress is assessed via a 15-item survey scored from 0-3 where higher scores indicate greater level of post-traumatic stress. | baseline, 6 weeks, 3 months, 6 months, 12 months, 24 months post surgery |
| Change in Tampa Scale of Kinesiophobia 11 (TSK-11) Score | Fear of re-injury is assessed via an 11-item survey scored from 1-4 where higher scores indicate a greater fear of re-injury. |
