a Relaxation time (τ) of each group. b Correlation between Osteoarthritis Research Society International (OARSI) score and τ. c Averaged attenuation coefficient of strain rate (ACSR) of each group. d Correlation between OARSI score and ACSR. e Correlation between τ and ACSR. Values are presented as the means ± standard deviations (error bars). *P < 0.05, **P < 0.01 compared between groups
