Not applicable Interventional University of British Columbia · NCT06195423

This study is testing if a 6-month online education and exercise program can help young people who have had ACL surgery prevent osteoarthritis and improve their knee health.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a 6-month virtual education and exercise therapy program called Stop OsteoARthritis (SOAR) for individuals aged 16-35 who have undergone anterior cruciate ligament reconstruction (ACLR) 9-36 months prior. Participants will be randomized to receive either the SOAR program or a minimal intervention control. The study will assess improvements in knee health, including pain, symptoms, function, and quality of life at 6, 12, and 24 months. Additionally, the trial will analyze the cost-effectiveness and implementation of the SOAR program.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 16-35 who are 9-36 months post-ACLR and currently live in British Columbia, Canada.

Not a fit: Patients with a previous diagnosis of knee osteoarthritis or those currently receiving knee care may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly reduce the risk of developing early-onset osteoarthritis in young individuals after an ACL injury.

How similar studies have performed: Other studies have shown promise in using education and exercise interventions to improve outcomes in knee injuries, making this approach both relevant and potentially impactful.
