Table 2 Anterior tibial translation under 5 Nm of varus and valgus torques, respectively

From: Varus-valgus instability in the anterior cruciate ligament-deficient knee: effect of posterior tibial load

 

Intact

ACLD

ACLDp

Anterior tibial translation at 30° of flexion (mm)

Under varus torque

+1.6 ± 0.7

+4.0 ± 0.9 a

0.0 ± 1.2

Under valgus torque

–0.8 ± 0.9

–0.8 ± 1.3

– 2.2 ± 1.4

Anterior tibial translation at 60° of flexion (mm)

Under varus torque

+2.2 ± 1.2

+3.9 ± 2.2 a

+0.3 ± 1.6

Under valgus torque

– 1.5 ± 1.4

– 1.9 ± 1.5

– 3.0 ± 1.7

  1. Mean ± standard deviation, the positive value indicates anterior tibial translation, and the negative one does posterior translation, a significant difference compared to the values in the Intact and the ACLDp (p = 0.01)
  2. Intact: intact knee, ACLD: ACL-deficient knee, ACLD P : ACL-deficient knee with additional 30 N of posterior tibial load
