Follow-up evaluation of the thickness of medial femoral cartilage

Regions	Group A (n = 24)	Group B (n = 25)	Group C (n = 25)
APFR	3.52 ± 0.47*	2.78 ± 0.42	2.81 ± 0.45
AMR	1.16 ± 0.24*	0.76 ± 0.11	0.81 ± 0.13
PMR	1.24 ± 0.26*	0.82 ± 0.12	0.85 ± 0.14
PCR	2.25 ± 0.31*	1.89 ± 0.28	1.91 ± 0.27

APFR, AMR, PMR, and PCR were calculated using the analysis of variance (ANOVA)

APFR—anterior patella femoral region; AMR—anterior meniscal region; PMR—posterior meniscal region; PCR—posterior condyle region

*Significant difference compared with the placebo controls (Group C)
