Figure 25.

Patellar maltracking seen in a 39-year-old man at physical examination. Axial (A, B) and sagittal (C, D) T2-weighted single-shot fast spin-echo MR images were obtained with quadriceps contraction (A, C) and without quadriceps contraction during a routine static acquisition at rest (B, D). The images obtained with quadriceps contraction (A, C) show increased patellar height and increased lateral tilt, with loss of patellotrochlear cartilage overlap (arrow in C).
