Fig. 4From: Kinematics and center of axial rotation during walking after medial pivot type total knee arthroplastyDistribution of all x-coordinates of the ICOR in each phase of gait. The “0” on the horizontal axis indicates the center of the tibial plateau. The LPP indicates lateral pivot proportion (%). ICOR, instantaneous center of axial rotation; ESt, early stance; MSt, mid-stance; LSt, late stance; PSw, pre-swingBack to article page
