Table 2 rTR and ATT during different movements in ACL-deficient, ACL-reconstructed and ACL-intact knees

Kinematic variable	ACL-deficient	ACL-reconstructed	ACL-intact
*Range of tibial rotation (in degrees; mean (SD))*
Level walking	13.7 (4.1) ^a(P = 0.15,ns)	14.1 (3.9) ^b(P = 0.12,ns)	17.3 (6.4)
SLHD	16.9 (3.7) ^a(P = 0.21,ns)	18.4 (3.4) ^b(P = 0.64,ns)	19.4 (5.5)
Side jump	16.6 (5.8) ^a(P = 0.08,ns)	18.3 (4.7) ^b(P = 0.24,ns)	20.7 (3.6)
*Anterior tibial translation (in mm; mean (SD))*
Level walking	4.6 (4.8) ^a(P = 0.13,ns)	4.8 (5.4) ^b(P = 0.25,ns)	6.6 (3.0)
SLHD	9.3 (5.1) ^a(P = 0.21,ns)	11.7 (9.2) ^b(P = 0.60,ns)	13.4 (7.2)
Side jump	6.7 (5.5) ^a(P = 0.65,ns)	8.8 (7.5) ^b(P = 0.78,ns)	7.7 (5.8)
