Table 1

Staining area for each of the five sections at the tibial attachment area of AM and PL bundle.

()	Area ± SD (25–75%)
	Zone 1	Zone 2	Zone 3	Zone 4	Zone 5
Staining	58.8 ± 29.1	31.8 ± 24.8	12.9 ± 13.1	13.2 ± 15.7	3.6 ± 5.8	<0.001
Area (%)	(28.2–83.3)	(8.9–52.6)	(4.4–23.6)	(2.0–28.9)	(0–4.5)
	<0.001	<0.001	<0.001	0.089	0.012
