Figure Lengend Snippet: Polyethylene wear analysis with the PolyWare software. A. Circles are fitted to the peripheries of the cup and femoral head shadows B. At the end of the analysis a solid cup model is added to the output. Right hips are flipped about the vertical axis to look like left hips prior to analysis.

Article Snippet: Analysis was performed by an experienced observer (LLA) with a computerized method (PolyWare Pro 3D Digital vs. 5.10; Draftware Developers, Conway, SC).

Figure Lengend Snippet: Bland-Altman plots and scatter plots, with lines of equality for repeatability measures for each of the 3 methods. Bland-Altman plots (columns 1 and 3); x-axis: average of two measurements; y-axis: the difference between 2 measurements (y = measurement 1 – measurement 2); red lines: 95% limits of agreement; dashed line: bias from 0; solid green line: y = 0 line; dots: individual double measures. Scatter plots (columns 2 and 4); x-axis: first measurement; y-axis: second measurement; maroon lines: lines of equality; EGS-RSA: radiostereometric analysis using sphere models; PW1: PolyWare using only the final follow-up radiographs; PW2: PolyWare using the postoperative and final follow-up radiographs.
