| 摘要 |
The present invention relates to an artificial knee joint that comprises a femoral component and a bearing member and prevents dislocation of the femoral component and, more specifically, to an artificial knee joint that comprises an upper surface, disposed on a post thereof, which performs a motion relative to a cam of a femoral component and prevents the cam of the femoral component from deviating from the inflection point between an upper curved surface and a lower curved surface by making the radius of curvature of the lower curved surface larger than that of the upper curved surface that exists on a portion extending rearward from the upper surface, and enables the femoral component to return while naturally descending along the upper surface, which is inclined at a predetermined angle, even in a case where the femoral component is dislocated, thereby preventing an increase in the amount of bone to be cut while increasing a jump distance. |
