New knee scan could slash diagnosis time and costs
NCT ID NCT07028476
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new way to diagnose knee sprains using a quick scan called Automated Dynamic Laximetry (LDA) instead of the usual MRI. About 80 adults with suspected ACL injuries will be split into two groups: one gets LDA first, the other gets MRI. The goal is to see if LDA can speed up diagnosis, reduce time in a knee brace, and lower healthcare costs, while still being accurate. If it works, MRI would only be used for complex cases needing surgery.
