AAS Ankle Activity Scale, given in median with ranges
* P < 0.05 compared to before injury level; † P < 0.05 compared to before operation; ‡ P < 0.05 compared to after operation. Overall significance assessed with Friedman’s tests. In case of significance, post hoc pairwise comparison was assessed with the Wilcoxon signed-rank test (for AAS) or by use of McNemar tests (sports participation)
