Locations and magnitudes of thickest cartilage thickness (CTh) and densest subchondral bone mineral density (sBMD) in the medial and lateral femoral compartments.

	Thickest CTh	Densest sBMD	P-values
Medial compartment
Anteroposterior location	44.9 ± 3.6%	43.6 ± 3.5%	0.014
Mediolateral location	69.3 ± 4.2%	70.0 ± 4.2%	0.357
Magnitude	2.1 ± 0.4 mm	1697.5 ± 70.1 HU	n/a
Lateral compartment
Anteroposterior location	64.8 ± 3.8%	59.5 ± 4.5%	<0.001
Mediolateral location	20.9 ± 2.2%	23.0 ± 3.3%	<0.001
Magnitude	2.1 ± 0.5 mm	1577.3 ± 71.8 HU	n/a

Location and magnitude data are presented as mean ± standard deviation of the 50 knees. Location data are in percent of the anteroposterior or mediolateral sizes of the standardized maps (see Fig. 3), whereas magnitude data are in mm for CTh and in Hounsfield units (HU) for sBMD.

P-values in bold indicate statistically significant differences between CTh and sBMD locations (p < 0.05).
