The normality column indicates whether the data needed to be transformed or not. Group was TE or PET-SI. Weeks post was baseline, 2 or 8-weeks post-surgery. GxW is the group by weeks post-surgery interaction term. Gait velocity was included as a covariate in the model. ROM – range of motion; NS – not significant. p < 0.05 considered significant. p < 0.1 also included.
