| Description | Biomechanical studies assessing the major knee ligaments, such as the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament (MCL), and lateral collateral ligament (LCL), have been conducted using various methodologies. However, despite the anterolateral ligament (ALL) being regarded as the important ligament for the stability of the knee, a lack of biomechanical research focusing on the ALL exists to date. Moreover, studies assessing the relative mechanical properties of each ligament of the knee are insufficient. Therefore, this study examined the mechanical properties of the ALL, MCL, and LCL and considered the relative differences between these ligaments. Twenty-one fresh cadaver knees were chosen to investigate the mechanical properties. The width, thickness, and length were measured. The stiffness, ultimate load, and elastic modulus were also tested. The MCL showed the greatest ultimate load (498.5 N) and the highest stiffness (71.97 N/mm), and the ALL presented the smallest ultimate load (146.64 N) and lowest stiffness (42.62 N/mm). Meanwhile, the LCL was second concerning the ultimate load (263.22 N) and stiffness (69.70 N/mm). The elastic modulus of the LCL (493.86 MPa) was greater than those of both the MCL and ALL (326.75 MPa and 345.27 MPa, respectively). There was no difference between the sides according to the different properties of all the ligaments. A sex difference was apparent only concerning the ultimate load for all the ligaments. Each ligament showed similar stiffness irrespective of its size; for this reason, stiffness should be considered initially and while conducting biomechanical simulations of these ligaments. |
