(Fig 1-B.08) Marching cleft sign in a radial tear

https://youtu.be/QM6RshHhemE https://youtu.be/nKQsItyKAtM Radial tears can occur in various parts of the meniscus, including the anterior/posterior horns or the body. The manifestation of these tears on MRI varies based on the tear's thickness and location. Full Thickness Radial Tear - The Ghost Meniscus Sign: Partial Thickness Radial Tear - The Truncated Triangle Sign: The Cleft Sign in Radial ..

(Fig 1-B.07) Full-thickness Radial Meniscal Tears

https://youtu.be/a8ghran53aw https://youtu.be/nKQsItyKAtM 📌 Significance of Radial Tears: • Unlike horizontal and longitudinal tears, radial tears significantly disrupt meniscal hoop strength. • The deeper the tear, the more it impacts the biomechanical function of the menisci. 🔬 Radiologic Signs to Detect Radial Tears: 1. Truncated Triangle Sign: • Truncation of the free edge, usually indicatin..

(Fig 1-B.06) Partial-thickness Radial Meniscal Tears

https://youtu.be/EzEwAo6-UvE https://youtu.be/nKQsItyKAtM 📌 What is a Radial Tear? • A radial tear runs perpendicular to the tibial plateau and the meniscus’s long axis, transecting the longitudinal collagen bundles. 📌 Significance of Radial Tears: • Unlike horizontal and longitudinal tears, radial tears significantly disrupt meniscal hoop strength. • The deeper the tear, the more it impacts the..

(Fig 1-B.04) Longitudinal-Vertical Meniscal Tears with ACL tear

https://youtu.be/dyIYdmbO13U https://youtu.be/nKQsItyKAtM There is a strong link between peripheral longitudinal tears of the menisci and anterior cruciate ligament (ACL) tears. Specifically, about 90% of medial meniscus (MM) and 83% of lateral meniscus (LM) peripheral longitudinal tears are associated with ACL tears. Meniscal tears are found in 41-68% of acute isolated ACL injuries, 85-91% of c..

https://youtu.be/-Q3zyTw9YQo https://youtu.be/nKQsItyKAtM #MeniscalTears #verticaltear #longitudinaltear #ACLinjury #VisualizingMSK Type of Tear: Longitudinal Tear Characteristics: Runs perpendicular to the tibial plateau. Runs parallel to the long axis of the meniscus. This is commonly seen in younger patients following knee trauma. There is a notable association between peripheral longitudinal..

(Fig 1-A.18) anterior meniscofemoral ligament of the medial meniscus, infrapatellar plica

https://youtu.be/mxyxCuCKwzM https://youtu.be/kEuMzUrHD0M https://youtu.be/kEuMzUrHD0M"Anomalous insertion of the medial meniscus (AIMM) into the anterior cruciate ligament (ACL) is an uncommon condition, seen in about 0.52% of arthroscopy cases. It involves a ligament extending to the ACL from the anterior horn of the medial meniscus, near the root. This variant accessory insertion appears on s..

(Fig 1-A.15) Additional peripheral attachments to the MM

https://youtu.be/C-I1T1POols https://youtu.be/kEuMzUrHD0M The knee joint capsule, part of layer III, forms the deep MCL, with its meniscotibial and meniscofemoral components, along the medial aspect of the knee. It then continues posteriorly, where it is reinforced externally by the POL and expansions from the semimembranosus. More posteriorly, the posteromedial joint capsule passes deep to the ..
