The Results of Tukey's Test for Comparison of T2 Values and Difference in T2 Values between Pre- and Post-Contrast Images

Note.- Hypothesis: pre T2, post T2, and difference in T2 values between pre- and post-contrast images of former group are significantly lower than those of latter group. Modified Noyes classification grade 0 = normal, grade 1 = increased T2 signal intensity within morphologically normal cartilage, grade 2A = superficial partial-thickness cartilage lesion less than 50% of total thickness of articular surface
