Fig. 4From: Mobile medial pivot (lateral slide) type total knee arthroplasty exhibits a medial pivot pattern: three-dimensional motion analysis using cadaveric kneesChanges in the femoral component’s X-axis (FCX) angle on the tibial component’s axial plane (rotational angle). The FCX was projected onto the axial (XY) plane of the tibial component’s coordinate system. The rotational angle from full knee extension to maximum flexion was calculatedBack to article page
