From: Evaluation of the theoretical optimal angle of the tibial tunnel in transtibial anatomic posterior cruciate ligament reconstruction by computed tomography

Parameter Mean Standard ± Deviation P
Total (n = 408) Male (n = 225) Female (n = 183)
L1 (mm) 40.1 ± 7.6 41.1 ± 7.0 38.8 ± 8.0 .002
TOA (°) 35.4 ± 7.9 35.1 ± 7.2 35.8 ± 8.6 .352
L2 (mm) 47.0 ± 11.1 48.0 ± 10.8 45.8 ± 11.3 .046
L3 (mm) 26.8 ± 11.4 27.2 ± 10.9 27.3 ± 12.0 .463
  1. 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)
