The results from the three treatment groups are compared with those of the knee articular cartilage. The only significant difference between the groups is the shear intermediate result versus the other intermediate values (P<0.05; shown by an asterisk). The three treatment groups approximate the collagen fibril angles found in articular cartilage, while the controls demonstrate random angularity.
