| Résumé : | Ligaments and tendons are fibrous connective tissues that connect the structures of the musculoskeletal system, enabling joint stability and force transmission, and finally motion. They consist of packed and oriented collagen fibers embedded in a water-based ground substance and show a high degree of architectural organization. Ligaments and tendons enter bones at the entheses, specialized structures with a transitional composition and architecture, which are relatively diverse depending on the location and biomechanical environment. Ligaments and tendons have a nonlinear mechanical response when subjected to tensile loads, and show viscoelastic behaviors such as creep and recovery, stress relaxation, and hysteresis. Their biomechanics has been investigated in numerous studies and shows a large variability depending on the biomechanical function of the tissue; in other words, their mechanical properties are influenced by skeletal maturation and aging, which involves a decrease in the water content and a stiffening of the collagen fibers due to cross-linking or due to exercise. |
