Zusammenfassung

In der Knieendoprothetik trägt die Patella zur Aufrechterhaltung einer fein abgestimmten Balance bei, die von der Position und Konfiguration der patellaren und femoralen Gelenkflächen, dem Winkel der Quadriceps-Sehne (Q-Winkel) und der Patellarsehne sowie der Spannung der medialen und lateralen Retinakula abhängig ist. Bei Beugung des Kniegelenkes greift die Patella in die Patellagrube ein und folgt dieser Grube über den gesamten Bewegungsumfang. Die Patella-Spitze (Apex patellae) bleibt bei normalem Knie in der medianen AP-Ebene. Um dieser Position Rechnung zu tragen, muss auch die Patellagrube in dieser Ebene liegen.
