Keshmiri, Armin ; Springorum, Hans Robert ; Baier, Clemens ; Zeman, Florian ; Grifka, Joachim ; Maderbacher, Günther


Patellar maltracking due to incorrect component alignment is considered as a main reason for anterior knee pain after total knee arthroplasty (TKA). In contrast to coronal and axial component placement, the influence of sagittal component alignment on patellar kinematics has not been investigated so far. In ten lower cadaveric limbs, TKAs were implanted using a commercial computer navigation ...
