Predicting second injuries after ACL surgery using video technology
Official title: Predicting second injuries after primary ACL reconstruction using clinically accessible videography
Funded at Univ of North Carolina Chapel Hill · NIH-11041104 · Data updated 2026-11-12
This study is looking at how to help people who have had ACL surgery avoid getting hurt again by tracking their movements and activities for 18 months, so we can learn more about what might lead to a second injury.

Who could benefit from this research
✓Could help
Ideal candidates are individuals who have recently undergone primary ACL reconstruction and are preparing to return to unrestricted physical activity.
✕Less likely to help
Patients who have not had ACL surgery or those with previous ACL injuries may not benefit from this research.
What this research studies
This research investigates how to predict the risk of second injuries in patients who have undergone primary ACL reconstruction. It utilizes innovative, clinically accessible videography to collect data on patients' movements and physical activity levels after their surgery. Participants will be monitored for 18 months through electronic surveys to assess their recovery and any subsequent injuries. The study aims to enhance understanding of factors that contribute to re-injury, ultimately improving patient outcomes.
Why it matters
Potential benefit: If successful, this research could lead to better prevention strategies for second ACL injuries, enhancing recovery and long-term health for patients.
How similar studies have gone: Previous research has shown promise in using motion capture technology for injury prediction, but this specific approach utilizing videography is relatively novel.
