Figure 3From: Bone marrow lesions from osteoarthritis knees are characterized by sclerotic bone that is less well mineralizedQuantitative measures of the trabecular structure for each of the four locations. (a) Trabecular thickness (Tb.Th*). (b) Structure model index (SMI). (c) Trabecular spacing (Tb.Sp*). (d) Trabecular number (Tb.N*). Cores from the lesion area exhibited the highest Tb.Th* but lowest SMI. Differences in trabecular structure were also noted between the matched and medial locations. Each bar represents the mean, and error bars represent one standard deviation. *Significant differences between groups (P < 0.05). #A trend (0.05 ≤ P < 0.10).Back to article page
