Claims (15)

1. The system of the knee prosthesis, which includes a single tibial plateau (2) with two grooves (7) slip and a solid femoral component (3) with two condyle sliding surfaces (6), the interval and shape of which are consistent with the tibial grooves (7) slip characterized in that this system, as an alternative to the integral femoral component (3), includes a pair of unconnected, femoral condyle condyles (10), the shape of the sliding surfaces of which is consistent with the tibial grooves (7) of sliding, and establishes strement (30), which gives the condyle condoms (10) a relative position coordinated with the tibial grooves (7). 2. The knee prosthesis system according to claim 1, characterized in that the shape and spacing of the sliding surfaces (6) of the condylar cups (10) coincides with the shape and spacing of the condylar sliding surfaces (6) of the entire femoral component (3). 3. The knee prosthesis system according to claim 2, characterized in that the position of the condylar resection surfaces (11, 12, 13) of the whole femoral component (3) and the position of the condylar cups (10) are the same. 4. The knee joint system according to claim 3, characterized in that it includes a caliber (20) of the saw with matching cutting planes for the whole femoral component (3), as well as for the condylar cups (10). 5. The knee prosthesis system according to claim 4, characterized in that the saw gauge (20) has a removable blocking insert (23) in the intercondylar region (24). 6. The knee prosthesis system according to one of claims 1 to 5, characterized in that the condyle cups (10) are facing each other with parallel side surfaces (37) and that the mounting tool (30) has suitable parallel parallel connecting surfaces (36). 7. The knee prosthesis system according to claim 6, characterized in that the mutual interval of the parallel connecting surfaces (36) is made with the possibility of stepwise regulation, respectively, to different intervals related to different levels of the condyle cups (10). 8. The knee prosthesis system according to claim 7, characterized in that the adjustability is based on the use of replaceable parts (32). 9. The knee prosthesis system according to one of claims 1 to 8, characterized in that the connecting surfaces (36) are formed, each, by a fixed sponge (35) of separate clips corresponding to the condylar cups (10) (33). 10. The knee prosthesis system according to claim 9, characterized in that holders (32) of various widths are provided for fastening the clamps (33). 11. The knee prosthesis system according to claim 10, characterized in that both clamps (33) are removable in the same direction of disconnection from the holder (32). 12. The knee prosthesis system according to one of claims 9 to 11, characterized in that the condylar cups (10) and clamps (33) are equipped with interacting protrusions (46) and recesses (47) that set against each other. 13. The knee prosthesis system according to one of claims 9 to 12, characterized in that the jaws (35, 40) of the clamps (33) act in the LM direction on the condyle cups (10) and are equipped with adjustable support (50) of the sliding surfaces. 14. The system of the knee prosthesis according to one of claims 1 to 13, characterized in that test condylar cups are provided that have outside the hole area (61) covered by the fixing tool (30) for the fixing pins (60). 15. The knee prosthesis system according to claim 14, characterized in that the condylar cups (10) have at least one fixing spike (14), and the test condylar cups instead of this spike have an opening (62) for the fixing bolt (63) ) with the head lowered into this hole (62).
