From: Partial rupture of anterior cruciate ligament: preliminary experience of selective reconstruction
a Sagittal T1-weighted MR image revealing diffuse thickening, poor definition of anterior edge of ACL (arrows) with increased signal intensity within the ACL substance; b 3D PD-weighted, sagittal multiplanar reformatted (MPR) image showing abnormal intrasubstance high signal intensity of middle and distal third of ACL (arrowheads) and well-discernible fibers in proximal region (arrow); c axial T1-weighted MRI showing focal fluid signal along the midsubstance of ACL (arrow) in the intercondylar notch. Posterior fibers of ACL remain attached to femur (arrowhead), while anterior fibers seem to wear thin and detach (asterisk)
