The correlation between knee kinematics and self-reported outcome854Figure 2. Scatterplots of correlations between anterior tibial translation (ATT) and IKDC or ACLRSI scores. R2 = explained variance. a = during level walking, b = during Single Leg Hop, c = during Side JumpABCapproximately 20 degrees during a SLH.49 This may imply that the greater rTR as shown in the present study may in fact be a manifestation of a more natural movement of the knee, and not a sign of increased rotational laxity. We therefore conclude that more normal knee kinematics after ACLR are correlated to better self-reported knee function and psychological readiness. The aim for ACLR therefore must be to restore pre-injury knee kinematics, rather than strictly pursuing regaining knee stability. This asks for a patient specific approach during ACL reconstruction. We have observed that less rotation is related to poorer self-reported knee function and less psychological readiness. In the past, over-tensioning of the graft, and thus limiting rTR, has been suggested to reduce knee function.5 However, this explanation seems unlikely, as during level walking, less rotation does not seem to be related to poorer self-reported knee function. A more convincing argument could be found in altered movement strategies. Previous research has shown that ACLR individuals Mark Zee.indd 85 03-01-2024 08:56
