Abrégé
(EN) The present invention relates to a PS-type artificial knee joint implant with which a gap balance may be adjusted to achieve a stable deep flexion operation, burden on medical personnel or a patient may be reduced, and the patient may perform a natural flexion movement. An artificial knee joint implant (1) of the present invention comprises femur components (100, 200, 300) selectively installed at a distal portion of a femur of the patient, and tibial inserts (400, 500, 600) selectively installed at a proximal portion of a tibia of the patient. Each of the femur components (100, 200, 300) comprises a cam portion (203) disposed between rear portions of two femur joint surfaces (107, 107; 207, 207; 307, 307). The tibial inserts (400, 500, 600) comprise posts (402, 502, 602) which may be connected to the cam portion (203). The posts (402, 502, 602) have different antero-posterior positions.
