Postoperative MRI findings, arthroscopic appearance, and tibial bone tunnel enlargement of cross-sectional area.

Graft intensity on MRI: low, iso, high (n)
1 year	3, 4, 0 (n = 7)
2 years	3, 2, 0 (n = 5)
Arthroscopic appearance: A, B, C (n)	7, 0, 0
Tibial bone tunnel enlargement of cross-sectional area (%)
1 year	9.9 ± 40.9 (n = 7)
2 years	4.2 ± 25.5 (n = 5)

The arthroscopic appearance of the synovium coverage of each graft was graded as A (completely covered), B (partially covered), or C (almost uncovered).

*Significant difference between 1 year and 2 years (P < 0.05).
