Kang KT, et al. - Researchers sought to clarify the influence of the posterior tibial slope (PTS) on knee joint biomechanics after posterior-stabilized (PS) total knee arthroplasty (TKA) using a computer simulation. As an excessive increase in the PTS could lead to the progressive loosening of the tibiofemoral (TF) joint due to a reduction in collateral ligament tension and failure of the post in a polyethylene (PE) insert, a surgeon ought to be prudent in terms of determining the PTS. In view of these findings, a more individualized approach of optimal PTS determination was supported by the experts.
