Biomechanical data for tendon-to-bone healing in rats were collected on three groups of animals: placebo (PBS, n=10); GSK126 (n=11); BMP2 (n=10). Measurements were made using (a) custom-made electromechanical testing machine with custom-made clamps, and a 250 g Model 31 load cell, to assess (b) p-values derived using the Kruskal-Wallis test on (c) force to failure, (d) stiffness, (e) elongation, and (f) energy adsorption.
