In this scenario, the flap tear mimics a bucket-handle tear, yet distinct differenc..

https://youtu.be/sMbeDDeLTXs https://youtu.be/nKQsItyKAtM 🔍 Exploring Displaced Meniscal Tears in MRI Understanding meniscal tears is key in knee MRI. Let’s break down the three main types of tears involving displaced meniscal material: 1️⃣ Bucket-Handle Tear with Displacement 2️⃣ Flap Tear with Displacement 3️⃣ Free Fragment Displacement ⚠️ Why It Matters: Identifying any displaced fragments is..

https://youtu.be/fy92wt6sc88 https://youtu.be/nKQsItyKAtM Insight into Horizontal Flap Tears of the Meniscus Patterns of Displacement: For medial meniscus tears, 93% of fragments are located medially or posterolaterally, commonly in the superior or inferior recesses. In contrast, lateral meniscal fragments exhibit a more varied distribution. In medial cases, two-thirds show the fragment displace..

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..

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..
