Axial view of a standardized tibial plateau with representative cartilage contact areas and centroid locations. Rater one cartilage contact area and centroids are in red and rater two cartilage contact area and centroids are in blue. The SEM for these measurements is 0.22 mm and 0.72 mm for the X and Y components of the medial centroid; 0.66 mm and 0.28 mm for the X and Y components of the lateral centroid, and 3.22 mm2 and 1.08 mm2 for the medial and lateral contact areas
