https://youtu.be/wmpIaimU2gE The anatomic variation of the anterolateral fixation of the lateral meniscus to the ITB, which we have termed the “accessory iliotibial band–meniscal ligament” or “AIML.” An AIML was present in 13.3% of all patients (136/1019). AJR Am J Roentgenol. 2019 Oct;213(4):912-917. Although the attachments of the anterior and posterior horn are relatively consistent, the ante..

https://youtu.be/he2-XqAyvaA * The popliteomeniscal fascicles arise from the periphery of the posterior horn of the lateral meniscus and form a posterolateral meniscocapsular extension, which creates the popliteus hiatus. * The fascicles not only form the hiatus, which allows the popliteus tendon an avenue to course intra-articularly and maintain the integrity of the joint but stabilize and cont..

With popliteus tears, it is important to note - the site of the tear (intra- articular or extra-articular), - the extent of tear (partial or full-thickness), - the presence of a bone fragment if there has been tendon avulsion - degree of tendon retraction Partial-thickness tear of the popliteus tendon, High-grade partial tearing of the PT at its femoral insertion Most popliteus tears are extra-a..

The nondisplaced component of a flap tear may demonstrate a changing slope contour of its superior surface. Criteria for diagnosis of a flap tear based on sagittal images include: * A vertical tear encompassing the inner third of the meniscus,either coapted or noncoapted * Relative deficiency of the inner third of the inferior meniscal surface with associated blunting of the remaining inferior l..

Treatment of avulsion fractures of the PCL depends on the degree of avulsion fracture displacement. Conservative therapy is generally performed if the degree of avulsion fracture displacement is mild, whereas surgery is performed in patients with significant displacement and posterior tibial instability. In the past, internal fixation was highly invasive, requiring a marked opening of the back o..

A 13-year-old girl rode her bike 30 minutes a day to school for two months with anterior knee pain without any history of direct trauma. what is the diagnosis? Sinding Larsen Johansson Syndrome (SLJS) is a juvenile osteochondrosis and traction epiphysitis affecting the extensor mechanism of the knee Some authors classify Sinding-Larsen-Johansson disease as a pediatric version of "jumper's knee"...
