MC = mean change in µm or %, SD = standard deviation, DIFF = mean difference between changes, CI = 95% confidence intervals of differences between changes (lower / upper limit), SL = Significance level after Bonferroni-Dunn correction: The significance (p value) of the differences between changes in JSN and no-JSN knees was computed using non-parametric Wilcoxon rank-sum tests and is reported in the table without adjustment for multiple comparisons. Medial and extended ordered values showing significant differences after Bonferroni-Dunn correction (p<0.0063 for medial, p<0.0031 for extended ordered values) are marked with *.

Ordered values were computed from subregional changes in 8 (medial approach)/ 16 (extended approach) subregions in the medial (medial approach) / medial and lateral (extended approach) femorotibial joint. Ordered value (OV) 1 = subregion showing the most negative change (decrease in ThCtAB) in each subject, OV 2 = subregion showing the second most negative change, ….OV 8 (medial approach) / 16 (extended approach) = subregion showing the smallest negative or the greatest positive change (increase in ThCtAB).
