Fig. 2A–D.

A representation is shown for each of the four unique shape features defined through principal component analysis that were correlated with abnormal knee kinematics after ACL injury but before surgical reconstruction, including: (A) the height of the medial femoral condyle (MFC), represented by Femur 18; (B) the sphericity of the medial femoral condyle, represented by Femur 10; (C) the length of the lateral tibial plateau, represented by Tibia 20; (D) tibial slope, represented by Tibia 19. S = superior; I = inferior; L = lateral; M = medial; A = anterior; P = posterior.
