Comparison of tensile (A, left) and compressive (B, right) strain distributions between 3D (blue) and slice-based (red) finite element (FE) models across the subchondral bone (SCB) depth within the simulated dorsal-oblique slice. Strains represent 90th percentile values within 3 mm-wide mediolateral subdivisions corresponding to the lateral condyle (LC), lateral parasagittal groove (LPSG), medial parasagittal groove (MPSG), and medial condyle (MC). The plotted SCB depth spans ~ 0–16 mm (rather than 0–20 mm) because the sagittal ridge (SR) region, showing minimal strain, was excluded. Peak strains occurred near the distal (most superficial) SCB surface, particularly in regions of lytic bone. The y-axis represents SCB depth, with 0 mm at the AC–SCB interface (distal) and 16 mm at the deepest SCB (proximal).”
