Wear particulate measurements for bovine articular cartilage explants showing significant (*p < 0.05) increases in (a) particulate number and (b) volume when compared to unloaded CTRL, ENVR, and BASE groups at respective time points (n = 9 per group, 1, 2, 6, 24 h). No differences between CTRL, ENVR, or BASE groups were detected [(a) p > 0.97, (b) p > 0.90)].
