(Fig 1-B.35) Guess what? Classification of Ramp Injuries https://youtube.com/shorts/ZHs4E3wbEzA?feature=share https://youtu.be/nKQsItyKAtM Ramp lesions are categorized into five types based on their characteristics. Type 1 is an isolated posterior superior meniscocapsular tear, while type 2 involves a partial tear in the same region. Type 3 represents either a partial posterior inferior tear or ..

The system was originally conceived based on arthroscopy. 1️⃣ Type 1: Partial, Stable Root Tear 2️⃣ Type 2: Complete Radial Tear within 9 mm from the Bony Attachment 3️⃣ Type 3: Bucket Handle ..

https://youtu.be/rJKppYoJgYg https://youtu.be/nKQsItyKAtM Arthroscopic Classification of Meniscal Root Tears: Type 2 Sagittal Ghost Sign: This sign is characterized by a hyperintense white signal intensity that leads to the disappearance or abrupt blunting of the normal low-signal-intensity meniscus tissue. It is typically observed on a sagittal image. Axial Radial Defect Sign: The axial radial ..

https://youtu.be/im9FJXRg6Ho https://youtu.be/nKQsItyKAtM MRI Classification of Posterior Medial Meniscal Root Injuries: (AJR 2014; 203:1286–1292) Choi et al. introduced an MRI-based classification for posterior medial meniscal root lesions. This classification encompasses a range of MRI findings related to meniscus posterior root attachment issues, including degeneration, partial tears, and com..

https://youtu.be/d7WmGVVonms https://youtu.be/nKQsItyKAtM Parameniscal Cyst: Parameniscal cysts are commonly used and well-established secondary or indirect signs of a meniscal tear. They, along with meniscal extrusion and subchondral marrow edema, play a crucial role in increasing the diagnostic confidence of radiologists, particularly in cases with technical limitations or equivocal findings. ..

It's significantly more likely to occur in knees with a posterior root tear, but can also be seen in cases of larg..

This sign has been recently identified as an indicator of medial meniscus posterior root tears. "Visualizing MSK Radiology: A Practical Guide t..

https://youtu.be/w113IDroK1s https://youtu.be/nKQsItyKAtM Both primary and secondary MRI findings can aid in the diagnosis of posterior root tears. Among the primary MRI signs of root tears, three commonly used findings are: Sagittal Ghost Sign: This sign is characterized by a hyperintense white signal intensity that leads to the disappearance or abrupt blunting of the normal low-signal-intensit..
