Mechanical properties of CS-FS scaffolds. Comparison of (A) maximum tensile strength, (B) Toughness, and (C) Young's modulus of untreated FS (O-FS), different CS-FS scaffolds and natural tendon. (The data of natural tendons obtained from previously reported study [38].) Tensile stress-strain curves (D) and Strain at failure (E) of O-FS and each CS-FS scaffold. (F) Ashby diagram of toughness and young's modulus for reported tendon tissue engineering scaffolds [[63], [64], [65], [66], [67], [68], [69], [70], [71], [72], [73], [74]]. This indicates that the mechanical strength of CS-FS scaffolds with a certain amount of mineralization is completely suitable for tendon repair.
