This study aims to investigate the impact of the anterolateral ligament (ALL), a recently discovered component of the knee ligaments, on knee stability. The rationale for this research arises from the limited understanding of the role of the ALL in anterior-posterior and internal-external knee motion stability. The study utilizes machine learning techniques to model and simulate changes in knee motion due to ligament injuries during walking. Validations were conducted by comparing the musculoskeletal model of the human body and ligament properties with the results of previous cadaver experiments. The simulations showed a significant increase in internal tibial rotation when both anterior cruciate ligament (ACL) and ALL injuries are applied, as opposed to only ACL injuries. These results imply the significant influence of the ALL in ACL-deficient knees on knee rotational stability. This finding could provide valuable insights into knee joint injuries and their treatments.

Cruciate ligaments of the knee provide passive constraints to the knee. The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) provide stability to the knee joint. The objective of this study was to analyze and observe the changes of knee joint kinematics following to unilateral ruptures of the ACL and PCL of the same virtual model using a forward-dynamics simulation. A musculoskeletal model with 92 Hill type muscles and 31 nonlinear spring damper ligaments were used in dynamic solver environment. A gait controller was trained to generate walking cycles and unilateral ligament injuries were created by removing either ACL or PCL. The peak posterior tibial translations in mid-stance phase were -6.0 ± 0.8 mm, -0.3 ± 1.4 mm, -3.4 ± 0.9 mm for the intact, ACL deficient, and PCL deficient models, respectively. The models with no cruciate ligaments showed a significant increase in tibial anterior translation than intact model.
