Description

The invention relates to a prosthetic assembly for the knee joint.
The object of the invention relates to the technical sector of medical sciences.

It is known to use for certain lesions of the knee, prostheses intended to reconstruct the joint between the femur and the tibia. Generally, this type of prosthesis is limited in number; there is essentially a distinction between monobloc trochleo-bicondylar prostheses, patellar prostheses and mono-compartmental prostheses. This limitation in number and shape of the prostheses generate certain drawbacks because, depending on the lesion to be treated, only the type can be used. closer to the prosthesis so that the result obtained cannot be considered satisfactory
Indeed, either the prosthesis is under-adapted to the treatment of the knee to be carried out or the prosthesis is SU-adapted to the treatment to be carried out which may thus affect the undamaged areas. For example, monocomponent prostheses are not shaped to fit between either the internal condyle or the external condyle Similarly there is no internal and external trochleocondylar prosthesis.

 The problem being thus posed, the invention set itself the goal of breaking down, and of modulating, the knee into several parts corresponding to the different possible lesions and of producing, for each of its parts, a prosthesis which is particularly well adapted in shape and size.

 To this end, a new monobloc trochleobicondylar prosthesis is executed, the shapes and profiles of which are determined to adapt to the anatomy of the knee, in particular of the femur, considered according to a representative sample. From this basic prosthesis which is suitably equipped with anchoring studs, we produce: - an external trochleo-condylar prosthesis, - an internal trochleo-condylar prosthesis, - a mono-external prosthesis, - a mono-internal prosthesis, - a patellar prosthesis.

 A set was thus produced comprising for each knee six different types of prosthesis each corresponding to the lesion to be treated. Preferably, each type exists in three sizes: large, small, medium.

 The invention is set out below in more detail with the aid of the drawings which represent the shapes and profiles of each type of prosthesis, it being emphasized that the prostheses illustrated correspond to the right knee and are illustrated to the scale 1 corresponding has the big size.

 - Figures 1, 2, 3 and 4 relate to the monobloc trochleo-bicondylar prosthesis, Figure 1 being the anterior view, Figure 2 the side view, Figure 3 the rear view, Figure 4 the top view corresponding to figure 2.

 - Figures 5, 6, 7 and 8 relate to the internal trochitocondylar prosthesis, Figure 5 being the anterior view, Figure 6 the side view, Figure 7 the rear view, Figure 8 the top view corresponding to FIG. 6.

 - Figures 9, 10, 11 and 12 relate to the external trochleo-condylar prosthesis, Figure 9 being the anterior view, Figure 10 the side view, Figure 11 the rear view, Figure 12 the top view corresponding to figure 10.

 - Figures 13, 14, 15 and 16 relate to the mono-external prosthesis, Figure 13 being the front view, Figure 14 the side view, Figure 15 the rear view, Figure 16 the corresponding top view in Figure 14.

 - Figures 17, le, 19 and 20 relate to the mono-internal prosthesis, Figure 17 being the front view, Figure 18 the side view, Figure 19 the rear view, Figure 20 the corresponding top view in Figure 18.

 - Figures 21, 22, 23 and 24 relate to the patellar prosthesis, Figure 21 being the front view, Figure 22 the side view, Figure 23 the rear view, Figure 24 the top view corresponding to the figure 22.

 The monobloc trochleo-bicondylar prosthesis illustrated in FIGS. 1 to 4 comprises a part (1) which acts as a patellar shield, extends in a perpendicular or substantially perpendicular plane by profiled half-lobes (2) and (3) separated by a notch (4) leaving a common part (5) between said lobes (2) and (3). In the case of the right knee, the lobe (2) is profile in section to correspond to the mean radius of curvature of the internal condyle. Conversely, the lobe (3) is profiled in section to correspond in section to the mean radius of curvature of the external condyle.

 The internal trochleo-condylar prosthesis (Figures 5, 6, 7 and 8) comprises the patellar shield (1) extended on one side only, in a plane perpendicular or substantially perpendicular, by the lobe (2) whose profile in section corresponds at the mean radius of curvature of the internal condyle. Opposite the lobe (2), the common part t5) is cut at a bevel (ó) at a determined angle corresponding to the normal patellar stroke.

 The external trochl # o-condylar prosthesis Figures 9 10, 11 and 12) is similar to the internal trochleo-condylar prosthesis, the only difference being the implantation of the lobe (3) and the bevel cut (7) which are reversed.

 The patellar prosthesis (Figures 21, 22, 23 and 24) is made from the condylar shield (d) extended in a plane perpendicular or substantially perpendicular, by the common part (5) whose lateral ends (8) and (9) are cut at a bevel to correspond respectively to the external and internal patellar stroke.

 Importantly, the length of the patellar shield (1) is determined to receive all possible anatomies (high or low kneecaps).

 The mono-external prosthesis shown in Figures 13, 14, 15 and 16 only includes the lobe (3) whose profile in section corresponds to the mean radius of curvature of the external condyle. Conversely, the mono-internal prosthesis shown in FIGS. 17, 15, 19 and 20, comprises only the lobe (2) whose profile in section corresponds to the mean radius of curvature of the internal condyle.

 Importantly, each prosthesis has directly or in an attached manner, depending on the nature of the material composing it, anchoring studs (10). These studs are suitably positioned projecting from the internal face of the prostheses to resist the various pressure parts to which the prosthesis is subjected.

 According to the invention, for each type of prosthesis, the studs (10) - have the same location and the same shape. Two studs are formed in overflow from the internal face of each of the lobes (2) and (3), while a stud is formed in overflow from the internal face of the common part (5) relating to the patellar shield. The length of the patellar shield stud is greater than that of the studs relating to the lobes (2) and (3).

 The lobe anchoring studs (2) and (3) are separated and possibly extended laterally by braced webs (11).

 According to the invention, six types of prostheses were therefore created for each of the knees, each type being produced in three sizes, ie a total of 36 prostheses.

 The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more especially indicated; on the contrary, it embraces all its variants.
