Figure 1. Average cross-sectional map of all patients correlating T1ρ values with corresponding trochlea Noyes Scores. At baseline, both sides (A, B) are correlated with Tlρ values in the patella, LT, and the trochlea. At 6 months, the trochlea Noyes Scores of the injured knee (C) are no longer correlated with any Tlρ values, while the contralateral trochlear Noyes scores remain correlated with the patella and LT (D).

Figure 2. Average cross-sectional p-value and longitudinal difference (C, D) maps of all patients. In the age-adjusted cross-sectional comparison, there is greater deviation in the MFC at 6 months (B) between the two groups than at baseline (A). In the longitudinal comparison, the group with lesions at baseline (D) show a greater longitudinal increase in T1ρ values than the group without initial lesions (C), especially in the weight-bearing regions.
