Figure 3.

Bar graph representing ultrasonic findings in rabbits with cartilage defects treated with cell/scaffold implants. Group C, control defect group; Group T-4, tissue-engineered-cartilage group at 4 weeks after implantation; Group T-12, tissue-engineered-cartilage group at 12 weeks after implantation. The error bars represent the standard deviation of each group. The percentage maximum magnitude is expressed as the maximum magnitude of the measurement area in the operated knee, divided by that of the intact cartilage of the opposite, nonoperated knee. *P < 0.05 on the nonparametric Mann–Whitney U test.
