Chapter 116Both subjective knee function and psychological readiness to return to sports have been studied extensively in the context of ACL reconstruction. However, although not much is known about the link between knee kinematics and subjective knee function and/or psychological readiness to return to sports, a strong association is possible. The range of tibial rotation could be related to muscular activity but also to bony anatomy. Anatomical (bony) factors such as the tibial slope are related to the amount of anterior tibial translation,5 but this has not been studied for the range of tibial rotation. As shown in Figure 3, a steeper posterior tibial slope leads to more anteriorly directed forces on the tibia as the femur pushes down on the tibial plateau during stance. Dejour et al. showed in a cadaveric study that, in the absence of the ACL, every increase of 10° in posterior tibial slope leads to a 6-mm increment of passive anterior tibial translation.Figure 3.
