Definitions
- the present invention relates to improvements to total knee prostheses and their method of assembly.
- the technical field is that of specific knee prostheses which indeed require particular techniques because of the complexity of the joint which must, in addition to its rotational mobility function, keep in particular a stability both lateral and antero -postior while ensuring the support of the weight of the body.
- knee prosthesis Whatever the total knee prosthesis used, it is certain that it has a "life time” limited, and often shorter than that of the patient on which it was implanted, because as indicated above the articulation of the knee. knee is very stressed and the surfaces in contact as moving parts and even bone anchors may be damaged: the prosthesis must be replaced one day.
- a stabilized posterior prosthesis to a stabilized lateral prosthesis which corresponds to a hinge pivot system.
- This change requires in fact to provide, before the operation and next to the operating table, the availability of both types of prostheses with two types of ancillaries and if the change decision occurs while the posterior prosthesis stabilized has already been put in place, the surgeon must proceed with its extraction to place the prosthesis pivot pivot hinge.
- the problem posed and solved by the present invention is therefore to avoid the drawbacks mentioned above of availability and change between two prostheses meeting different instability criteria during the same surgery to implant a total knee prosthesis and which are especially encountered during a revision operation to replace a first prosthesis.
- the front and any so-called anterior portion of the prosthesis will be referred to as those corresponding to the same orientation as the front of the knee capable of receiving this prosthesis, likewise for the posterior parts corresponding to the back of the prosthesis.
- knee those lateral corresponding to the sides of the knee, those superior or top corresponding to the orientation of the side of the femur and those below or below the side of the tibia.
- a femoral implant comprising at least one anchoring pivot at its upper part and capable of being fixed in a femur, a so-called anterior wall corresponding to the front orientation of the prosthesis and two limbs curved extending posteriorly from this anterior wall, forming condyles and separated by a hollow inter-condylar space in the form of a groove, delimited by the inner edge of these condylar branches and the inner face of the anterior wall, and
- a tibial implant comprising at least one anchoring pivot at its lower part and able to be fixed in a tibia, and a support plate able to support the supports of the condyles of the femoral implant,
- these femoral and tibial implants are adjustable between a first so-called postero-stabilization mounting configuration and a second laterally stabilized or hinged or rotational pivoting configuration configuration, and each having a portion common to these two configurations, including at least the previous elements specific to each implant, and another interchangeable portion adapted to each configuration and as described below as preferred embodiments.
- FIGS. 1A and 1B show two perspective views, of three quarters front and rear, of a total knee prosthesis according to the invention, fully mounted in postero-stabilized configuration.
- FIG. 2 is a perspective view of three quarters of a top of a femoral implant according to the invention, without its anchor pad, with the presentation of choice of mounting two inter-condylar cassettes one stabilized posterior and the other in rotary pivot.
- FIG. 3A shows the same femoral implant as FIG. 2 seen from below and before mounting a cassette in a rotary pivot.
- FIG. 3B represents the same femoral implant as in FIGS. 2 and 3A in a rear perspective view, with its anchor stud and after mounting a cassette in a rotary pivot.
- FIGS. 4A, 4B and 4C show a perspective view of three quarters of a top of a tibial implant according to the invention, with its common part according to FIG. 4A and its choice of mounting of its interchangeable part constituted by one of the two intermediate trays one according to Figure 4B for the postero stabilized assembly and the other according to Figure 4C for mounting rotary pivot.
- Figures 5 and 6 show two views in perspective, three quarters of top and front, of a tibial implant according to Figures 4, fully mounted in these two configurations postero-stabilized in Figure 6 and rotary pivot in Figure 5.
- a total knee prosthesis 1 according to the invention is composed at least:
- a femoral implant 2 comprising at least one anchoring pivot 11 at its upper part and capable of being fixed in a femur, a so-called anterior wall 3 corresponding to the front orientation of the prosthesis and two curved branches 5 extending posteriorly from this anterior wall 3, forming condyles and separated by a groove-like hollow inter-condylar space 4, delimited by the inner edge of these condylar branches 5 and the inner face of the anterior wall 3, and
- a tibial implant 10 having at least one anchor pivot 14 2 at its lower part and adapted to be fixed in a tibia, and a support plate 15 adapted to receive an intermediate plate 11 supporting the supports of the condyles 5 of the femoral implant 2.
- these femoral and tibial implants 10 are adjustable between a first postero-stabilization mounting configuration according to FIGS. 1, 4B and 6, and a second so-called rotary pivot mounting configuration according to FIGS. 3, 4C. and 5, and each having a portion common to these two configurations, including at least the previously described elements specific to each implant, and another interchangeable portion adapted to each configuration as described below as a preferred embodiment.
- the femoral implant 2 comprises means for attaching at least one interchangeable part that can be mounted and dismounted from the common part of this femoral implant 2, and which is:
- the attachment means of the transverse element 7 and the balance 9 consist at least on the one hand of orifices 6 formed in the inner walls of the branches 5 which, forming the edges thereof, surround the groove 4 and on the other hand transverse axes 8 passing through these orifices 6 and supporting either the transverse element 7 or the pendulum 9.
- this transverse element 7 is in the form of a first cassette 19i whose front face closes the cage able to receive the post-stabilization pad 13 of the tibial implant 10 and the surface, which extends this front face on the lower and rear part of the cassette 19i, is shaped to roll against the surface of the stud 13 during the rotation of the implants relative to each other, and this cassette 19i comprises at its upper part, behind its anterior face and above its rear part, a pin 7i which protrudes on either side of the volume of the cassette s' inserting in the inter-condylar groove 4, and which is adapted to cooperate with and in a mortise 63 made in the side walls of this groove.
- the balance 9 pivoting about the transverse axis 8 2 is mounted between two cheeks 17 of a U-shaped part forming a second cassette 19 2 inserting into the inter-condylar groove 4 and whose base of the U bears against the inner face of the anterior wall 3.
- the tibial implant 10 comprises means for fixing at least one interchangeable part consisting of an intermediate plate 11 supporting the supports of the condyles 5 of the femoral implant 2 and which is adapted to be mounted and dismounted from the common part of this tibial implant 10; this common part comprises at least one anchor pivot 14 2 at its lower part and adapted to be fixed in a tibia, and a support plate 15 adapted to receive the interchangeable portion which is composed at least:
- the parts of femoral and tibial implants are assembled and at least the femoral implant 2 an anchor pin 14i at its upper part, a so-called anterior wall 3 corresponding to the front orientation of the prosthesis and two curved branches 5 extending posteriorly from this anterior wall 3, forming separate condyles and by a groove-like hollow inter-condylar space 4 delimited by the inner edge of these condylar branches 5 and the inner face of the anterior wall 3, and comprising at least for the tibial implant 10 an anchor pivot 14 2 at its lower part and a support plate 15 adapted to bear the support of the condyles (5) of the femoral implant 2, then,
- the femoral implant 2 is taken to have a first interchangeable portion as previously described and shown in FIG. 2 and for the tibial implant a first interchangeable portion as described above and shown in FIG. 4B. ,
- the first femoral implant 2 is replaced or replaced by the first interchangeable parts, by a second interchangeable portion as previously described and shown in FIGS. 2 and 3A, and for the tibial implant, by a second interchangeable portion as described above and shown in Figure 4C.
