Anterior Laxity, Lateral Tibial Slope, and In Situ ACL Force Differentiate Knees Exhibiting Distinct Patterns of Motion during a Pivoting Event: A Human Cadaveric Study

Knee instability following anterior cruciate ligament (ACL) rupture compromises function and increases risk of injury to the cartilage and menisci. To understand the biomechanical function of the ACL, previous studies have primarily reported the net change in tibial position in response to multiplanar torques, which generate knee instability. In contrast, we retrospectively analyzed a cohort of 13 consecutively tested cadaveric knees and found distinct motion patterns, defined as the motion of the tibia as it translates and rotates from its unloaded, initial position to its loaded, final position.
