Functional Score. (A) Mean values of Functional Score in the control group and I-ONE therapy group during the study. Vertical bars represent the standard error. *p < 0.0001, ^p < 0.005, ^§p < 0.05, p values refer to a comparison between groups at each follow-up visit by two tailed heteroschedastic Student’s t-test. ⁺p < 0.05, statistically significant difference versus pre-op. (B) Mean changes in Functional Score in control and I-ONE groups during the follow-up compared with baseline values. Vertical bars represent standard errors.
