FIG. 9.
FEBio optimization results from unconfined compression (FEU) versus results from indentation testing (FEI) on paired (A) acellular agarose hydrogels and (B) engineered cartilage constructs after varying periods of in vitro culture. Constitutive model parameters for Young's modulus (EY), ksi, and permeability significantly correlated between the two testing modalities, although greater variation was observed in the living engineered constructs. The regression lines between sample types were not significantly different. Color images available online at www.liebertpub.com/tea
