Histological score of articular cartilage.

Femoral condyle	Normal group	Tet group	OA group
Structural changes	0.2±0.40	3.0±0.63 *	3.8±1.17^#
Cellular changes	0.4±0.49	1.6±0.80 *	1.8±0.75^#
Safranin staining	0.4±0.49	1.8±0.75 *	2.2±0.75^#
Tide mark	0.2±0.4	0.4±0.49 *	0.6±0.49^#
Sum of score	1.2±1.17	6.8±1.33 *	8.4±1.85^#

Values are the means ± SD. ^#𝑃<0.05 when Normal group compared with OA group, *𝑃<0.05 when Normal group compared with Tet group.
