The lateral femoral notch sign: a reliable diagnostic measurement in acute anterior cruciate ligament injury

1

The lateral femoral notch sign (LFNS) is a potential diagnostic tool for acute anterior cruciate ligament (ACL) injuries.
2

The study aimed to evaluate the validity and reliability of LFNS depth measurement in conventional radiographs.
3

Patients aged 12 to 45 with traumatic knee injuries were included, while those with chronic conditions were excluded.
4

Four blinded physicians assessed the LFNS depth and location on radiographs to determine inter- and intra-observer reliability.
5

The findings suggest that LFNS measurement could enhance the diagnosis of ACL injuries when MRI is not available.
