X-ray of knees showed slightly low-lying patella with diminished bulk of quadriceps tendon just above the patella in either knee [Figures 1 and 2]; soft tissue calcification was seen in the suprapatellar region of the right knee [Figure 1].

T2-weighted MRIs in sagittal plane revealed discontinuity between distal quadriceps tendon and upper pole of patella in both knee joints with the intervening space filled with hyperintense signal intensity, in definite contrast to hypointense signal intensity of tendon [Figures 3 and 4]; small joint effusion was seen in the suprapatellar region on either side [Figures 3 and 4].
