Revisiting meniscal anatomical variants of the knee: a high-resolution 7-Tesla MRI study

Question Anatomical variations of the number and insertion sites of meniscal roots are documented in anatomical and imaging studies. Findings High-resolution 3D dual-echo steady state on a 7-T MRI facilitates the visualization of the number of roots and their respective osseous insertions for both menisci. Clinical relevance The menisci demonstrate considerable variability in both root number and their insertion locations, particularly the posterior lateral meniscus exhibits up to three root insertions. Understanding anatomical variants is crucial for the accurate interpretation and reporting of knee imaging.
