Using motivational feedback to improve recovery after knee surgery

Impact of Motivational Feedback on Levels of Physical Activity and Quality of Life by Activity Monitoring Following Knee Arthroplasty Surgery - Randomized Controlled Trial Nested in a Prospective Cohort (KneeActivity)

Not applicable Interventional Odense University Hospital · NCT06005623

This study is testing if using an activity tracker that gives encouraging feedback can help people recover better after knee surgery compared to just tracking their activity without feedback.

What this trial studies

This randomized controlled trial aims to determine if physical activity following total or unicompartmental knee arthroplasty can be enhanced through the use of an activity tracking device that provides motivational feedback, compared to tracking without feedback. The study will also explore how pre-surgery physical activity levels predict post-surgical outcomes such as length of hospital stay, return to work, and overall quality of life. By addressing the gap in understanding how daily physical activity impacts rehabilitation, this trial seeks to provide high-level clinical evidence on the effectiveness of motivational feedback in improving patient satisfaction and recovery.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 40-85 who are scheduled for primary total or unicompartmental knee arthroplasty and can understand Danish.

Not a fit: Patients who have difficulty adhering to study protocols, refuse standard care, or have certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved rehabilitation outcomes and higher patient satisfaction following knee arthroplasty.

How similar studies have performed: While few studies have specifically examined the impact of motivational feedback on rehabilitation after knee arthroplasty, similar approaches in other areas of rehabilitation have shown promising results.
