Fig. 3

This figure represents the results of the range of motion between the two groups at each time. Range of motion was significantly greater in the viscosupplementation group at 2 weeks post-surgery compared to the control group. (Viscosupplementation group 131.5° vs Control group 121.0°, P = 0.044) Mann-Whitney test was used to compare the data. Asterisks indicate values that were significantly different between the two groups (P < 0.05)
