The correlation between tibial slope and dynamic knee kinematics1075and ‑11.5 (±3.54) degrees.35 Average medial PTS in ACL-injured subjects was between +1.8 (± 3.5) and ‑12.1(± 3.3) degrees.35We cannot state whether the aforementioned compensation mechanisms are able to limit ATT in subjects with higher levels of PTS. Dejour et al. report a significant increase of passive ATT with PTS > 12°8, Li et al. report increased passive ATT with PTS of 10°and Webb et al. report increased risk of ACL injury and graft failure with PTS > 12°.23,34 Observed PTS did not reach these values in our population. It would be of interest to additionally investigate the relation between PTS and ATT during in vivo motion. The ΔPTS variable is theoretically interesting to explore further with respect to tibial rotation. ConclusionIn contrast to passive ATT, which is significantly correlated to PTS, little (if any) to weak correlations were found between dynamic ATT and PTS. A compensation mechanism seems to be able to correct for the anatomical influence of PTS on dynamic ATT during high-demand tasks. Moderateto-strong correlations between PTS and dynamic rTR were found one year after ACL reconstruction. These findings warrant prudence in the use of a pure anterior closing-wedge osteotomy in ACL reconstruction; the effect of an anteromedial opening wedge on dynamic ATT and rTR may be further explored.
