a: A normal ACL, which is best depicted in the sagittal imaging plane on MRI. The fibers of the ACL (arrows) appear taut and parallel the roof of the intercondylar notch, but should not touch the roof of the notch. b: Acute ACL disruption. Matthew D. Milewski et al.

a: A sagittal T2-weighted image showing the normal appearance of the PCL (arrow) as a low- signal intensity, arcuate-appearing, band-like structure arising along the intercondylar notch portion of the medial femoral condyle and inserting on the posterior sla...

a, b, and c: Coronal T1-weighted MRI scans through the posterolateral corner of the knee, demonstrating the normal appearance of the distal biceps femoris musculotendinous junction (arrowheads and black arrow), conjoined tendon (long arrows), and popliteus...

a: A coronal T2-weighted image demonstrating the normal MCL (long arrows), which appears as a low-signal intensity, band-like structure extending along the medial aspect of the knee. Matthew D. Milewski et al. J Bone Joint Surg Am 2011;93:1735-1745 ©2011 by The Journal of Bone and Joint Surgery, Inc.

a: A normal medial patellofemoral ligament visualized on an axial T2-weighted image as the band-like structure extending from the medial patellar facet, then blending with the deep fibers of the vastus medialis obliquus muscle to insert on the adductor tube...

a and b: Coronal (a) and axial (b) T2-weighted images of the knee, demonstrating large bucket- handle fragments of the medial meniscus (short arrows) and lateral meniscus (long arrows), both displaced into the intercondylar notch. c: Sagittal T2-weighted ima...

a, b, and c: Grade-III osteochondral defect of the medial femoral condyle. Matthew D. Milewski et al. J Bone Joint Surg Am 2011;93:1735-1745 ©2011 by The Journal of Bone and Joint Surgery, Inc.
