Table 2 Means (SD) and p values of peak antero-posterior (AP) and vertical ground reaction forces (GRF) (N), knee joint moment (Nm/kg), AP and vertical ground reaction impulses (Ns) during forward-thrust phase and extension phase of the STS between the SR and MR limbs.

From: Biomechanical influence of TKA designs with varying radii on bilateral TKA patients during sit-to-stand
