Hip shape may predict ACL tears, new study suggests
NCT ID NCT07271277
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study looks at whether a hip condition called femoroacetabular impingement (FAI) is more common in people who have torn their ACL, a major knee ligament. Researchers will use 3D MRI scans to examine the hips of 50 adults with ACL tears. The goal is to see if hip shape issues might increase the risk of knee injury. No treatment is given—this is an observational study to gather information.
