The Young

18–30 (n = 153)

39.2 ± 6.5

34.0 ± 6.7

45.6 ± 9.6

25.4 ± 10.6

The Middle-aged

31–45 (n = 104)

41.6 ± 7.2*

37.3 ± 7.3*

48.9 ± 10.6*

28.7 ± 9.9*

The Elderly

46–60 (n = 151)

39.9 ± 8.6

35.5 ± 9.1

47.2 ± 12.6

  1. Compared to the young, *P < 0.05. L1 the thickness of cancellous bone, TOA the theoretical optimal angle, L2 the distance from anterior tunnel aperture to anterior end of tibial plateau, L3 the distance from anterior tunnel aperture to the tibial tuberosity (lowest edge of patellar ligament attachment)
