Suprapatellar fat-pad (SPFP) on T2-weighted MR images. (a) Normal SPFP (without mass effect and signal alteration) (arrowhead); (b) SPFP with mass effect (arrowhead); (c) SPFP with signal intensity alteration (arrowhead); (d) SPFP with both mass effect and signal intensity alteration (arrowhead).

Associations between mass effect and signal intensity alteration of SPFP and knee pain in unadjusted analyses. (a) SPFP mass effect was significantly associated with total WOMAC knee pain, pain on flat surface, pain on stairs, pain in bed, pain when standing; (b) SPFP signal intensity alteration was significantly associated to total WOMAC knee pain, pain on stairs, pain in bed, pain when sitting and pain when standing.

4. Fig. 3
Associations between mass effect and signal intensity alteration of SPFP and knee radiographic changes in unadjusted analyses. (a) Mass effect was significantly associated with both JSN and osteophytes; (b) Signal intensity alteration was significantly associated with JSN but not significantly associated with osteophytes.
