✅ Knee MRI Mastery/Chap 1. Meniscus103 (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.. 2024. 1. 20. (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.. 2024. 1. 19.
