(A) Laminar analysis was performed by dividing the patellar and trochlear cartilage into two equal layers. Red regions correspond to deep layer cartilage. Yellow regions correspond to superficial cartilage. (B) T1ρ map of the PFJ for a control subject without OA.

3. Fig. 2
Sagittal plane knee moment curve during the stance phase of walking of a sample trial. Joint moment is expressed as external moment. Positive and negative values indicate knee flexion and extension moments, respectively. KFM impulse was calculated as the area under curve when sagittal plane knee moment is positive.
