Signs of ACL tear on MRI- Resident's Corner


Case showing most of the signs of ACL tear on MRI, submitted by Dr Prashant Gupta and Dr Himani Agarwal

ANTERIOR TIBIAL TRANSLATION- >7MM IS SIGNIFICANT

ABSENT ACL, THIS IS PRIMARY SIGN, IT SHOULD NORMALLY BE PARALLEL TO BLUMENSAAT LINE WHICH REPRESENTS ROOF OF INTERCONDYLAR NOTCH


BUCKLED PCL, AN ANGLE LESS THAN 114 DEGREES IS SIGNIFICANT

MENISCAL TEARS- LATERAL MORE ASSOCIATED WITH ACL TEARS THAN MEDIAL
UNCOVERED POSTERIOR HORN LAT MENISCUS, THE TIBIAL LINE SHOULD NORMALLY NOT CROSS THE MENISCUS.

"NOTCH" IN LATERAL FEMORAL CONDYLE, CALLED THE "LAT. FEM. NOTCH SIGN". ITS DEPTH SHOULD BE >2MM.
KISSING CONTUSIONS IN THE "NOTCH" ON LATERAL CONDYLE AND ON POSTEROLATERAL TIBIAL PLATEAU.
