Table 4. Changes in knee cartilage thickness after the first injection after 12 months.

Mean baseline in mm = 2.15; mean at 12 months in mm = 2.45

T = time, SD = standard deviation, SE = standard error, P-value = probability value

Variable	Baseline (T1)	SD	SE	After 12 months of treatment (T2)	SD	SE	P-value  (two-tailed)
Mean tibial plate thickness in mm	2.15	0.67	0.076	2.38	0.63	0.072	0.000
Mean femoral plate thickness in mm	2.16	0.78	0.09	2.5	0.76	0.086	0.000
