“…Errors in femoral rotational alignment contribute to an imbalanced soft tissue envelope and lead to instability and a limited range of motion. [37][38][39] For both CR and PS knees, we found internal femoral component rotation of 158 created forces within the MCL that are above the published yield point of 453 N. 40 Regardless of whether the MCL would rupture, the larger MCL forces associated with internal femoral component rotation would likely be perceived as stiffness by TKA patients, which may inhibit postoperative function. The increase in LCL force induced by external rotation of the femoral component may be due not only to external rotation of the tibia with respect to the femur, but also a combination of rotation and translation.…”

“…The transepicondylar axis (TEA) of the femur generally is regarded as the gold standard axis for establishing the rotational alignment of the femoral component during TKA [13,35,40,49]. This axis is believed to best approximate the flexion-extension axis of the knee [13] and produces a balanced joint and the most normal patellar tracking [35] and minimizes patellofemoral shear forces [35].…”

“…Eine gerade mechanische Beinachse [9], eine adäquate Rotation der Prothesenteile [2,4,5,10,11,[13][14][15][16] und eine harmonische Balancierung der Weichteile in Extension und Flexion sind für das klinische Ergebnis nach endoprothetischer Versorgung mit einem kompletten Oberflächenersatz des Kniegelenks maßgeb-lich [6,9,10]. Die praktische Umsetzung macht die gegenseitige Beeinflussung dieser Parameter augenscheinlich und kann den Operateur zu Kompromissen zwingen [3,17].…”

“…Die Rotation der Prothesenteile ist als dritte Dimension bei deren Implantation Ende der 90er Jahre Anfang 2000 in den Mittelpunkt des Interesses gerückt [2,4,5,10,11,13,14,15]. Diesbezüglich haben sich folgende entscheidende Erkenntnisse herauskristallisiert:…”
