Development and validation of a clinical tool to semi-automatic measure three-dimensional TAR alignment on two-dimensional radiographs

Table 3 The distance between the tibial and talar component (in mm) over the x- and y-axis, given as mean with standard deviation (SD) with absolute difference between observers (∆), and inter-observer results with intraclass correlation coefficient and p-value between both observers (n = 8)
