https://youtu.be/CCFU0yNkwoU https://youtu.be/nKQsItyKAtM Insight into Horizontal Flap Tears of the Meniscus What Are Horizontal Flap Tears? Horizontal flap tears involve a short segment of the meniscus with the displacement of a meniscal leaf. These tears commonly result in the displacement of the meniscal fragment, usually found in the posterior intercondylar notch or the gutters. The medial m..

https://youtu.be/PjQ5Dk5ub4k https://youtu.be/nKQsItyKAtM Vertical Flap Tear, also known colloquially as the Parrot Beak Tear. This particular form of tear is notable for its unique composition and the resulting displacement pattern. Composition of the Tear: The Vertical Flap Tear is characterized by having both radial and longitudinal components. Origin and Progression: Classically, this injury..

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 ..

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..

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..

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..

MRI Appearance of Tear Appears as a horizontally oriented line of increased intrameniscal signal extending to the superior or inferior surface of the meniscus, typically near the free edge. Common Location Most common within the posterio..

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..
