Fig. 4From: The effect of knee joint rotation in the sagittal and axial plane on the measurement accuracy of coronal alignment of the lower limbScatter graphs are shown of a linear relationship between the ΔmTFA and the sagittal plane rotation of the knee. The analysis was performed in patients with a patellar rotation less than 3% (r2 = 0.039, P = 0.074) (a), in overall patients (r2 = 0.136, P < 0.001) (b), and in patients with a patellar rotation greater than 3% (r2 = 0.257, P < 0.001) (c), respectively. ΔmTFA delta value of the mechanical tibio-femoral angle, r2 the coefficient of determination. † The values are given as means and standard deviations, analyzed based on absolute valueBack to article page
