4 Imaging protocol Outline Cruciate and collateral ligaments Menisci Cartilage Bone marrow edema
5 Sequence Protocol
6 Sequence Protocol
7 Sequence Protocol Int FS: is a fat suppressed sequence with a long TR and a TE between that of a traditional PD (e.g. TE= 10-20) and a traditional T2 (e.g. TE=80-100). The advantage of this sequence is that the TE is short enough to maintain sufficient signal for visualisation of the anatomy (like a PD) yet long enough to be more fluid sensitive (like a T2).
8 Intra-articular, extrasynovia Anterior Cruciate Ligament Two main fiber bundles: anteromedial bundle (AMB) posterolateral bundle (PLB)
9
10 Non-contact trauma Anterior Cruciate Ligament High risk sports: Ski Soccer, american football Gymnastics LANDING, TWISTING and DECELERATION, particularly with knee in full extension ISOLATED ACL TEARS ARE VERY UNCOMMON Mamoru Niitsu. Springer 2013
11 Three main mechanisms of injury Pivot shift Hyperextension Clip injury Anterior Cruciate Ligament Sanders TG. Radiographics Oct;20 Spec No:S135-
12 Anterior Cruciate Ligament Mechanism of injury: PIVOT SHIFT INJURY
13 Anterior Cruciate Ligament Associated Findings Buckling of the PCL (steep course of distal portion of PCL)
14 Anterior Cruciate Ligament (ACL) Mechanism of injury: HYPEREXTENSION INJURY If a valgus force is also applied at hyperextension, the kissing contusions will be located medially Sanders TG. Radiographics Oct;20 Spec No:S135
15 Anterior Cruciate Ligament CLIP INJURY: O Donoghue triad or unhappy triad
16 Anterior Cruciate Ligament (ACL) MRI FINDINGS: Partial Tears Partial tears may appear as Focal loss of the normal striated appearance (leaving intact fibers on at least one slice) Increased signal intensity on T2-W images with mild swelling of the ligament. AMB constitute the primary (96%) restraining force to anterior drawer at 30 knee flexion Rupture of AMB is believed to be functionally equivalent to complete ACL tear Distinguish partial tears from complete ruptures may be difficult in sagittal plane 40-75% sensitivity 62-89% specificity Non-specificity of signal intensity changes Chen WT. Acta Radiol Sep;43(5):511 Stoller DW. Lippincot Williams & Wilkins 2007:
17 Anterior Cruciate Ligament (ACL) INTERPRETATION PITFALLS INTRALIGAMENTOUS GANGLION CYSTS Cysts are located in the proximal-middle portions of intact ACL Herniation of synovial tissue through capsular defect vs mucoid degeneration High signal on fluid-sensitive pulse sequences Do not enhance after intravenous contrast Roberts CC. Magn Reson Imaging Clin N Am. 2007;15 (1): 73-
18 Anterior Cruciate Ligament (ACL) Simple anterior cruciate ligament ganglion cyst involving the whole ligament
19 Anterior Cruciate Ligament (ACL) MUCOID DEGENERATION ( Celery Stalk Sign ) Mucoid degeneration/fusiform enlargement of the ligament May coesist with intraligamentous cyst
20 Anterior Cruciate Ligament (ACL) CHRONIC TEARS NON-VISUALIZATION of the ligament empty notch sign on coronal MR images ANGULATION of the ligament instead of a straight course Scarring and fibrosis BONE BRUISES typically not present LATERAL FEMORAL NOTCH SIGN Deepened sulcus Indicates a chronic insufficiency of ACL It may be seen in acute injury (impaction) Mamoru Niitsu. Springer 2013
21
22 Posterior Cruciate Ligament (PCL) Intra-articular, extra-synovial structure. Is the primary restraint against posterior subluxation of the tibia Two bundles similar to ACL, but more tightly grouped Two-to four-fold stronger than ACL uniform low signal intensity on MR Impossible to differentiate on MRI
23 Posterior Cruciate Ligament Mechanism of injury DASHBOARD INJURY It is caused by force on the anterior proximal tibia with the knee in flexion It is associated with anterior tibial and posterior patellar edema Associated with rupture of PCL and posterior joint capsule Sanders TG. Radiographics Oct;20 Spec No:S135-
24 Posterior Cruciate Ligament Chronic Partial Tear
25 Posterior Cruciate Ligament Complete Tear
26 Collateral Ligaments Classified in three grades: Grade 1: sprain or strain, mainly consisting of elongation of the ligament without any functional loss. Treated conservatively. Grade 2: partial tear. Grade 3: complete tear. Differentiating between grade 2 and 3 may be impossible (often written as grade 2 3 tear )) Mamoru Niitsu. Springer 2013 De Maeseneer M. Radiographics Oct;20 Spec No:S8
27 Medial Collateral Ligament Primary valgus + internal/external rotation stabilizer (Layer I: Thin sheet that overlies the two heads of the gastrocnemius and the structures of the popliteal fossa.) Layer II: Superficial layer of the MCL (tibial collateral ligament) Layer III: Deepest layer of the MCL called medial capsular ligament, which is continuous with the medial joint capsule. Mamoru Niitsu. Springer 2013 De Maeseneer M. Radiographics Oct;20 Spec No:S8
28 Medial Collateral Ligament
29 Medial Collateral Ligament Linear hyperintensity representing edema along the ligament s fibers due to sprain or strain can be seen. This imaging finding can also be found in medial meniscal tear and knee osteoarthritis. Coronal FS PDWI Mamoru Niitsu. Springer 2013
30 Medial Collateral Ligament Edematous changes can extend into the surrounding medial retinaculum and vastus medialis Mamoru Niitsu. Springer 2013
31 Medial Collateral Ligament Discontinuity of the fibers and signal abnormalities due to edema and hematoma Mamoru Niitsu. Springer 2013
32 Collateral Ligaments and Posterior Corners MCL tear More than half of MCL tear occurs at the (femoral) portion, but it can less commonly occur in the distal (tibial) portion Mamoru Niitsu. Springer 2013

43 Menisci Menisci are comprised of fibrous cartilage, mainly of type I collagen. Collagen fibers form two zones: 1. Peripheral zone: the outer third of the meniscus. Fibers are oriented in circumferential fashion resist longitudinal stresses 2. Inner zone: internal two-third of the meniscus. Fibers are radially oriented prevent longitudinal splitting due to excessive compression Radial fibers Circumferential fibers Aagaard H. Scand J Med Sci Sports Jun;9(3):13
44 Menisci Anterior horn Medial Lateral Posterio r horn
45 Discoid Meniscus
46 Meniscal Tears May be categorized into: TRAUMATIC result from excessive force on a normal meniscus DEGENERATIVE normal force on an abnormally degenerated meniscus Contact with the articular surface on one or two or more sequential images increases confidence of a tear (sensitivity > 90%) Abnormal meniscal morphology: second diagnostic criteria for a tear De Smet AA. AJR Am J Roentgenol Jan;176(1):6 Crues JV et al. Radiology Aug;164(2):445-
