Thesis (Ph.D.)--Northwestern University, 2005.

Injury to the anterior cruciate ligament (ACL) is commonly associated with mechanisms that stretch the ACL directly. How the ACL can also be injured through its impingement against the intercondylar notch, however, remains unclear. The extent to which previous studies have investigated this mode of injury has been limited to evaluating one-dimensional measurements of the intercondylar notch width as a predisposing factor. This thesis describes the development of a mathematical model that analyzes potential disruption of the ACL against the intercondylar notch accurately in three dimensions with the relevant knee structures characterized in detail. Based on measurements obtained from cadaveric experiments, a novel mathematical algorithm was devised to characterize the 3-D geometrical relationship between the ACL and complexly shaped surfaces of the intercondylar notch. Namely, the algorithm determines the deformed geometry of the ACL as it wraps around the surface of the intercondylar notch during impingement. Further, the algorithm is implemented to analyze impingement on an individual-specific basis in order to account for anatomical and anthropometric variations among individual subjects. Whether the ACL is susceptible to injury through impingement is determined by simulating tibiofemoral movements associated with ACL impingement on the individual subject's knee, which is geometrically reconstructed based on its magnetic resonance images (MRI), and implementing the algorithm to evaluate the physical interactions between the ACL and the intercondylar notch during the movements. The ACL is initially represented based on its functional anatomy, with refinements made in the later stages of the development of the model to include the complex 3-D fiber architecture of the ACL. The analysis results reflect the robustness of the mathematical modeling method, provide truthful descriptions of the ACL impingement in three dimensions, and contribute to the biomechanical characterization ACL impingement as an injury mechanism. Corroboration with the mathematical model is achieved by evaluating the changes in the mechanical properties of the ACL resulting from impingement in an ex vivo rat model. The mathematical modeling approach may be implemented in the surgical planning of ACL reconstruction to prevent graft impingement and the development of training and rehabilitation protocols to prevent ACL injuries.
