This study uncovered new insights on the local associations between cartilage thickness and T_1ρ relaxation time (a marker of cartilage proteoglycan content). Using Voxel-based relaxometry, this study quantified the longitudinal and cross-sectional thickness changes that occur in both the ACL-injured knee and the healthy contralateral in the lateral femoral condyle, medial femoral condyle, trochlea, medial tibia, lateral tibia, and patella and examined compartment-specific associations with relaxometry at various time points.
