Associations Between Deep Learning-Derived Infrapatellar Fat Pad Volume on MRI with Cartilage Thickness and Imaging Features of Knee Osteoarthritis: Data from the Osteoarthritis Initiative.

Significant interactions between IPFP Vol and subregion were observed for cartilage thickness and all three WORMS scores (all p<0.001).

Larger IPFP Vol was associated with greater cartilage thickness in the patella (β = 0.011 mm per cm³; 95% CI, 0.006 to 0.016) and lateral tibia (β = 0.015 mm per cm³; 95% CI, 0.010 to 0.019).
