The artificial whirbone implant of this creation,It substantially ties up to its ontology and supplies the acting surface contacted with femur equipped with one,The knee innermost model portion of shaping sector and a corresponding what inside the knee on the outside of the knee on the outside of a corresponding what knee is equipped at what acting surface,It is equipped with a fitting surface for engaging with real patella in the another end of opposite what acting surface,What fitting surface position corresponding with knee innermost model portion is convexly equipped at least one interior side bearing bolt foot,Position corresponding with shaping sector on the outside of knee is convexly equipped at least two outsides and supports bolt foot； AndThe big what of quantity system of the total outside bearing bolt foot of whole artificial whirbone implant totally in side bearing bolt foot quantity. In order to the lateral destructive power that can effectively keep out quadriceps muscle of thigh and cause, with relatively more actively reliable means prevent kneecap from laterally dislocating and overcoming the problems, such as patella tilt.本創作之人工髕骨植體，基本上係在其本體上設有一供與股骨接觸的作用面，於作用面處設有一對應於膝蓋外側的膝外側造型部及一對應於膝蓋內側的膝內側造型部，在相對於作用面的另端設有一供與真實髕骨接合的裝配面，於裝配面與膝內側造型部對應的位置凸設有至少一個內側支承栓腳，與膝外側造型部對應的位置凸設有至少兩個外側支承栓腳；以及，整體人工髕骨植體之全數外側支承栓腳之數量係大於全數內側支承栓腳之數量。俾可有效抵擋股四頭肌所引發之側向破壞力，以相對更為積極可靠之手段防止髕骨側向脫位及克服髕骨傾斜之問題。
