Effect of compressive strain on regional distribution of glucose and lactate diffusivities in porcine temporomandibular joint (TMJ) discs. (A) Glucose and (B) lactate diffusivities of TMJ discs versus mechanical strain (0%, 10%, and 20%) and disc region (anterior, intermediate, lateral, medial, and posterior). Sample size n = 6 porcine TMJ discs: 6 (disc) × 3 (strain) × 5 (region) = 90 diffusivity measurements.
