Collage of MR images exemplifying the features that were significantly more common in the split tear group. (a) Bone marrow edema in the posterior fibula. Note how the peroneus tendons pass directly behind the fibula (dashed arrow). (b) Bone marrow edema in the lateral talus. (c) Concave malleolar groove. Dashed arrow pointing at peroneus tendons. (d) Moderate joint effusion. Note the fluid expansion in both the anterior and posterior recess, but the anterior tibia is still in contact with fat tissue (dashed arrow) but not the talus (straight arrow). a – T2-weighted image with fat suppression, b – proton density-weighted image with fat suppression, c – T1-weighted image, d – T2-weighted image with fat suppression
