Detailed explanation-1: -Collagen also contributes   65–80% dry weight of tendons, with collagen crosslinks aiding the tendon structure to endure resistance from high-impact stresses and shear forces (Kannus 2000). Thus, collagen plays a vital role in maintaining tendon health and mitigating potential injury-risk in sport (Goes et al.

Detailed explanation-2: -For ligaments and tendons that display healing potential after injury, the major challenges are recovering their normal ultrastructural appearance, biochemical composition, and mechanical properties.

Detailed explanation-3: -The most abundant form of collagen in tendon and throughout the body is type I [13, 14]. Type I collagen fibrils are stiff structures that provide the tendon with its mechanical durability and strength.
