“…Magnussen et al (2011) reported medium-term survival and KSS scores for patients with residual postoperative varus alignment (HKA > 3°, varus) following TKA compared to patients with neutral postoperative alignment (HKA 0° ± 3°). Similar results were obtained by Vanlommel et al (2013) who reported significantly better KSS scores in patients with mild postoperative varus alignment (HKA 3–6°, varus) than in patients with postoperative neutral alignment (HKA 0° ± 3°) and severe varus (HKA > 6°, varus). Finally, Matziolis et al (2010) investigated 218 TKAs with a minimum follow-up of 5 years, and found similar survival rates and functional outcome scores (WOMAC and SF36) for aligned TKAs (HKA 0° ± 3°) and malaligned TKAs.…”

“…Furthermore, no patients required revision surgery. The observation of [28,30,41,54]. In the current study, it was observed that the mean Forgotten Joint Score (FJS-12) of these patients was higher (86.5) than the score for a normal control (82.5) in the index study on the FJS-12 from Behrend et al [4].…”

“…In der Literatur verdichtet sich die Datenlage, wonach sich einerseits mittels einer kinematischen Komponentenausrichtung oder der Unterkorrektur einer Varusfehlstellung bessere klinische Resultate erreichen lassen [3,11,17,22], während Studien mit ausreichendem Langzeit-Follow-up weiterhin die neutrale mechanische Beinachse hinsichtlich der Prothesenstandzeit als prognostisch günstig bewerten [4,7,12,15,23]. Ebenfalls uneinheitlich stellt sich in der internationalen Literatur die Messmethodik zur Bestimmung der Beinachse dar, da einerseits die Prothesenstandzeit mit dem anatomischen femorotibialen Winkel und den anatomischen Kniegelenkswinkeln anhand von Standarda.-p.-Aufnahmen des Kniegelenkes korreliert wird [7,19,20], andererseits in Studien die mechanische Achse anhand einer Ganzbeinstandaufnahme a.-p. die Grundlage für eine Standzeitanalyse darstellt [12,17,22] …”
