This document discusses using MRI to diagnose ligament injuries in the knee. It begins with an overview of MRI anatomy of the knee and expected pathology. It then discusses specific ligaments like the ACL, PCL, MCL and LCL. For the ACL, it shows images of acute tears, chronic tears and intrasubstance tears. It emphasizes knowing the knee anatomy well and correlating any abnormalities seen with clinical findings in order to apply the appropriate treatment.

• Primary signs of anterior cruciate ligament tear. Sagittal
intermediate-weighted images
• A: Typical appearance of ACL tear at the mid-substance
with fibres discontinuity of ACL . Residual stumps on femoral
and tibial sides are lax, thickened and increased in signal
intensity;
• B: Chronic ACL tear with absence of normal ACL fibres
compatible with complete resorption of fibres. PCL
• C: Acute high grade intrasubstance tear as characterized by
thickening and oedematous change of ACL fibres which
show increased signal intensity . The fibres are still in
continuity suggestive of partial ACL tear.
