Left knee of a 55‐year‐old female showing a medial meniscus (arrowhead) on (A) coronal PDW fat‐saturated at the level of the medial collateral ligament (arrows) without extrusion. Coronal PDW fat‐saturated magnetic resonance (MR) imaging slightly posterior (B) shows a tear with contact to the undersurface of the meniscus (dashed arrow) and adjacent bone marrow edema (asterisk). Supine relaxed ultrasound (C) of the medial meniscus (arrowheads) at the level of the medial collateral ligament shows slight meniscal extrusion with minimal change on supine stressed ultrasound (D). Weight‐bearing ultrasound (E) increases the meniscal extrusion severely. F, femur; T, tibia.
