"posterior cruciate ligament angle: the PCL angle (measured as the angle between lines drawn through the central portion of the tibial and femoral insertions of the PCL on the sagittal MRI images) decreases with time after an ACL injury; an angle less than 105 is considered "PCL buckling", which consists a clue to chronic ACL tear 1,5"

"ACL morphology: an oedematous and swollen ACL morphology (increased signal intensity on sagittal fat-saturated proton density images with a mass-like appearance) favours an acute tear, whereas chronic ACL tears usually have a hypointense and fragmented (secondary to fibrous scar) appearance or are absent in chronic tears 1; the chronically torn ACL fragments frequently scar to the lateral aspect of the posterior cruciate ligament 2,3"

"as fibrous scars have signal characteristics similar to the intact ligaments, a chronically torn ACL may be misinterpreted as normal. Focal angulations in the course of this low signal band are a clue to the correct diagnosis; however, they do not always exist 3"
