The study aims to identify the key points affecting the patello-femoral joint stability and stress pressure distribution. The finite element model of the knee joint with structures supplying patellar retinaculum is used. The femoral component is rotated along the mechanical axis for 5 degrees both medially and laterally. The stress pressure distribution is analyzed within patello-femoral joint during gait cycle.

Cilem teto prace je urćeni klicovych faktom, ktere ovlivnuji stabilitu patelo-femoralniho kloubniho spojeni. Dalśim cilem je urćeni rozłożeni napeti v tomto spojeni. Pro uvedenou analyzu je poużit drive definovany konećneprvkovy model kolenniho kloubu doplnćny o patelarni retinaculum. Pfidany dalsi ćtyfi vazy ćesky, dva vazy k femuru a dva vazy k tibii. Pfi analyze je kondylar twist uhel nulovy a tibialni plato nahrady je polożeno kolmo na mechanickou osu nohy (fyziologicky spravne nasazena totalni kolenni nahrada). Femoralni ćast nahrady je potom otaćena kołem mechanicke osy o 5 stupnu jak v medialnim, tak i v lateralnim smeru. Nakonec je provedena analyza rozłożeni napeti na patelofemoralnim kloubu behem chuze.
