ACL Deficiency Increases Forces on the Medial Femoral Condyle and the Lateral Meniscus with Applied Rotatory Loads

Conclusions:
ACL sectioning increased the net forces carried by the lateral meniscus and medial femoral condyle—and the anterior shear and lateral shear forces, respectively—in response to multiplanar valgus and internal rotation torque.

Clinical Relevance:
These loading patterns provide a biomechanical rationale for clinical patterns of intra-articular derangement such as lateral meniscal injury and osseous remodeling of the medial compartment seen with ACL insufficiency.
