(A) Ensemble-averaged sagittal plane knee angles. A positive value indicates KF. (B) Net external sagittal plane moments of force for individuals. A positive value indicates a net external KF moment and a negative value indicates a net external extension moment. Knee effusion (dotted) and without knee effusion (solid).
