3.0 Tesla scanner (Siemens Verio) using an 8-channel knee coil. Image 1: Sagittal PD_TSE_FS_320 (TR/TE 3500/36 ms, scan time 2 min 3 sec, slice thickness 3 mm); Image 2: Coronal PD_TSE_FS_320 (TR/TE 2100/36 ms, scan time 1 min 13 sec * 2, slice thickness 3 mm); Image 3: Axial T2_ME2D_320 (TR/TE 533/15 ms, scan time 1 min 48 sec * 2, slice thickness 3 mm).

Imaging Findings:
Mild increased intrasubstance STIR signal is seen near the proximal attachment of the patellar tendon with edema in the adjacent Hoffa’s fat pad, consistent with Jumper’s K
