Table 3 Descriptive statistics of the proximal tibial parameters among three height groups

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

Height group (m) Mean Standard ± Deviation
L1 (mm) TOA (°) L2 (mm) L3 (mm)
Total I- < 1.66 m (n = 161) 38.6 ± 8.2 35.5 ± 8.9 45.2 ± 11.6 25.7 ± 12.2
II - 1.66 to 1.75 m (n = 207) 40.8 ± 6.7* 35.3 ± 7.1 47.8 ± 10.4* 27.0 ± 10.2
III - > 1.75 m (n = 40) 42.4 ± 7.9* 35.4 ± 7.5 50.5 ± 11.5* 29.9 ± 13.2
  1. Compared to I, *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)
