Table I.

Relative % differences in the quantitative structural parameters of the mouse AC between paired DMM and CTRL samples in the medial and lateral condyles of the tibia at 4- and 12-week post DMM surgery. Percentage differences calculated between DMM/CTRL pairs of means; n = 4; *P < 0.05 for differences between 12-week medial vs 4-week medial parameters (computed by two-tails, unpaired, Student's t test)
