Fig. 3B —Medial meniscal flounce on routine knee MR images of 23-year-old man with no abnormality. Two continuous sagittal proton density-weighted (TR/TE, 3,300/16) images in neutral (A), maximally extended (B), and maximally flexed (C) knee in surface coil. From neutral to maximally extended position, flounce disappears with anterior migration of anterior horn. On maximally flexed knee, flounce also disappears with posterior migration of both horns. Distances representing anterior migration of anterior horn with more extension of knee (A in Fig. 1) are 0 mm in A, -2.1 mm in B, and 4.25 mm in C. Distances between posterior horn margin and posterior tibial margin (P in Fig. 1) are 5.31 mm in A, 5.35 mm in B, and 3.98 mm in C.
