Cadaveric biomechanical study using selective sequential ligament sectioning in 17 human knees to define each structure's individual and combined contribution to resisting posterior translation, varus rotation, and tibial rotation across 0–90° of flexion.
Understanding these biomechanical relationships helps explain why posterolateral corner injuries often present with complex instability patterns and why they frequently require multi-ligament reconstruction approaches rather than isolated repairs.
