Abstract

The knee prosthesis with rotary plate comprises a metal base (2) and a tibia plate (3) which are equipped with guide means (22, 22′, 22″, 26, 29, 5, 6, 5′, 9, 50, 51, 52, 13, 15, 18; 34, 34′, 34″, 35, 37, 7, 8, 10, 12, 53, 54, 55, 10′, 17) defining a center of rotation (C, C′) which may be offset from that of the tibia bone axis (YY′), so as to allow the tibia plate (3) to slide in rotation over the said base, the said guide means being positioned a certain distance away from the center of rotation (C, C′).

Description

  • The present invention relates to a knee prosthesis and more specifically to the device for assembling its tibia plate, which is made of plastic, on its metal base anchored beforehand into the tibia bone tissue. [0001]
  • Knee prostheses which comprise a plastic tibia part which is free to rotate about the tibia bone axis with respect to the metal base secured to the tibia are known. [0002]
  • This freedom of rotation is generally achieved via a male shaft integral with the plastic tibia part which engages with a bore made in the metal base. [0003]
  • Furthermore, this freedom of rotation may be achieved by a male shaft secured to the metal base which engages with a bore made in the plastic tibia part. [0004]
  • These connecting devices have certain drawbacks, namely the difficulty of inserting the plastic tibia plate once the metal base is in place on the tibia. These drawbacks are exacerbated when the posterior cruciate ligament is being kept, as this restricts access to the upper part of the tibia. [0005]
  • Furthermore, it is observed that the center of rotation is necessarily positioned at a point of the device or [sic] the bore can be made, that is to say in a part or [sic] there is enough material to make the said bore. This arrangement of the center of rotation is not strictly anatomical. [0006]

  • The knee prosthesis according to the present invention has a short height of the guide means and of their anterior positioning on the metal base which allows the tibia plate to be mounted on the said base via a strictly anterior approach, the said plate requiring upward clearance only by the height of the said guide means. [0039]
  • The description which will follow with reference to the appended drawings, given by way of nonlimiting examples, will allow a good understanding of the invention, its features and the advantages it is likely to afford: [0040]
  • FIG. 1 is an exploded perspective view illustrating the knee prosthesis according to the present invention. [0041]
  • FIGS. 2 and 3 are side views showing the knee prosthesis before the plastic tibia plate is fitted on the metal base. [0042]

  • FIGS. 15, 16 and [0047] 17 are views depicting a fifth alternative form of the knee prosthesis which has a cutout through which the posterior cruciate ligament can pass.
  • FIGS. [0048] 18 to 24 are views illustrating alternative forms of the knee prosthesis in which the metal base has two opposed guide upstands but one of which is borne by the center of rotation of the second.
  • FIGS. [0049] 25 to 27 are views depicting other alternative forms of the knee prosthesis according to the present invention.
  • FIGS. 28 and 29 are views illustrating guide means set out at the periphery of the metal base and of the tibia plate of the knee prosthesis. [0050]
  • FIGS. [0051] 30 to 32 are views showing guide means consisting of at least two vertical pegs integral with the metal base and which engage with a housing formed in the tibia plate.
  • FIGS. [0052] 1 to 3 show a knee prosthesis 1 comprising a metal base 2 and a tibia plate 3, whereas the femoral element is not depicted.
  • The metal base [0053] 2 consists of a horizontal disk 20 secured on one of its faces to an anchoring rod 21 allowing the said base to be fixed into the tibia of a patient.
  • The horizontal disk [0054] 20 comprises, on the opposite side to the rod 21, guide means which consist of an upstand 22 with an exterior profile in the shape of an arc of a circle. In this case, note that the center of rotation C of the upstand 22 is borne by the tibia bone vertical axis YY′.
  • The upstand [0055] 22 extending vertically above the horizontal disk 20 has a central part 23 integral on each side with two vertical edges 24 and 25 which are not as tall as the said central part.
  • In addition, the upstand [0056] 22 is positioned on the horizontal disk 20 of the metal base 2 a certain distance away from the center of rotation C.
  • The tibia plate [0057] 3, which is made of plastic, has a flat lower face 30 arranged in a horizontal plane parallel to the plane containing the disk 20 of the metal base.
  • On the opposite side to the face [0058] 30 the tibia plate 3 has an upper face 31 with two tracks 32 and 33 of concave profile which are intended to receive the condyles of the femoral element, not depicted.
  • The lower face [0059] 30 is pierced with a housing 34 with the same radius of curvature as the upstand 22 secured to the metal plate 2.
  • The housing [0060] 34 has cutaways 35 and 36 of a larger size which are intended to receive respectively the central part 23 and the lateral edges 24 and 25 of the upstand 22.
  • It can be seen that the tibia plate [0061] 3, and more particularly its lower face 30, is resting on the horizontal disk 20 of the metal base 2, that the upstand 22 enters the housing 34.
  • The latter has dimensions that exceed those of the upstand [0062] 22 so that the tibia plate 3 can slide freely in rotation about the center of rotation C of the said upstand 22 in the direction of the arrow F illustrated in FIG. 1.
  • The upstand [0063] 22, which is in the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • FIGS. 4 and 5 show a first alternative form of the knee prosthesis [0064] 1 according to the present invention.
  • The knee prosthesis [0065] 1 is identical to the one described earlier, that is to say that it comprises a metal base 2 and a plastic tibia plate 3.
  • The metal base [0066] 2 has, and this is what differentiates it from the one described above, the position of the guide means on the horizontal disk 20. In effect, the guide means consist of an upstand 22 in the shape of an arc of a circle and the profile of which is similar to the one described earlier, but the center of rotation C′ of which is offset from that C borne by the tibia bone vertical axis YY′.
  • Note that the center of rotation C′ can be positioned anywhere, either on the horizontal disk [0067] 20 or off it, while at the same time keeping the guide means on the said horizontal disk and more specifically at a particular point.
  • Just as before, the upstand [0068] 22 provided with its central part 23 and its lateral edges 24 and 25 enters the housing 34 formed in the lower face 30 of the plastic tibia plate 3 to allow the latter to slide in rotation over the metal base 2 and about the center of rotation C′ in the direction of the arrow F1 in FIG. 4.
  • The upstand [0069] 22, which is in the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • FIGS. [0070] 6 to 8 depict a second alternative form of the knee prosthesis 1 according to the invention.
  • The latter comprises a metal base [0071] 2 and a plastic plate 3 similar to those described in FIG. 1, but in which the guide means differ to allow for a better movement of the plate over the base.
  • Thus, the metal base [0072] 2 equipped with its horizontal disk 20 integral with its rod 21 comprises guide means which consist of two opposed upstands 22′ and 22″ in the shape of an arc of a circle. The upstands 22′ and 22″ have the same center of curvature which is coincident with the center of rotation C located on the tibia bone vertical axis YY′.
  • Provision may be made for the center of rotation of the upstands [0073] 22′ and 22″ to differ from the one C, that is to say offset as shown in the first alternative form in FIGS. 4 and 5.
  • Note too that the upstands [0074] 22′ and 22″ have a constant height over the entire circular-arc-shaped profile.
  • The tibia plate [0075] 3 has a flat lower face 30 with two opposed housings 34′ and 34″ intended to receive respectively the upstands 22′ and 22″ of the metal base 2. The housings 34′ and 34″ have a radius of curvature identical to that of the upstands 22′ and 22″.
  • It can be seen when the tibia plate [0076] 3, and more specifically its lower face 30, is resting on the horizontal disk 20 of the metal base 2, that the upstands 22′ and 22″ enter the housings 34′ and 34″.
  • The latter have dimensions greater than those of the upstands [0077] 22′ and 22″ so that the tibia plate 3 can slide freely in rotation about the center of rotation C in the direction of the arrow F3 illustrated in FIG. 6.
  • FIGS. [0078] 9 to 11 illustrate a third alternative form of the knee prosthesis 1 according to the present invention.
  • The knee prosthesis [0079] 1 is identical to the one described in FIGS. 1 to 3, namely it comprises a metal base 2 and a plastic tibia plate 3.
  • The metal base [0080] 2 comprises, on its horizontal disk 20, and on the opposite side to its anchoring rod 21, guide means which consist of the upstand 22 formed from a central part 23 and of two lateral edges 24 and 25.
  • Furthermore, the horizontal disk [0081] 20 comprises, at the center of rotation C of the upstand 22 which is borne by the tibia bone vertical axis YY′, a retaining peg 26 extending vertically above the said disk 20.
  • The retaining peg [0082] 26 constitutes a guide means that is in addition to the guide means formed by the upstand 22. Thus, the peg 26 is positioned on the center of rotation C of the tibia plate 3 on the metal base 2.
  • The retaining peg [0083] 26 consists of a cylindrical pin 27 integral with a head 28 whose outside diameter exceeds that of the said pin.
  • The additional guide means or peg [0084] 26 is an integral part of the pin 27, 28 to prevent the tibia plate 3 from lifting off the metal base 2 when the prosthesis is in motion.
  • The tibia plate [0085] 3 has, on its lower face 30, the housing 34 that receives the upstand 22 and a cutout 35 with inclined faces 36. When the plate 3 is mounted on the base 2, this cutout engages with the retaining peg 26 so that the head 28 lies above the inclined faces 36.
  • It can be seen that the retaining peg [0086] 26, when it engages with the cutout 35, allows the tibia plate 3 to be prevented from lifting under a tensile force when the said plate is sliding in rotation F4 on the metal base 2.
  • FIGS. [0087] 12 to 14 show a fourth alternative form of the knee prosthesis 1 according to the invention.
  • Thus, the metal base [0088] 2 comprises, opposite the upstand 22, and in the region of the center of rotation C which is borne by the tibia bone vertical axis YY′, a centering peg 29 extending vertically above the horizontal disk 20.
  • The centering peg [0089] 29 extends vertically above the horizontal disk 20 by a short height, constituting a guide means that is in addition to the guide means formed by the upstand 22.
  • The centering peg [0090] 29 consists of a short cylindrical pin.
  • The plastic tibia plate [0091] 3 comprises, on its lower face 30 and opposite the housing 34, a blind hole 37 intended to receive the centering peg 29 when the said plate is fitted onto the metal base 2.
  • The centering peg [0092] 29 provides a physical embodiment of the center of rotation C of the upstand 22 as the tibia plate 3 slides in rotation over the metal base 2.
  • The knee prosthesis [0093] 1 illustrated in FIGS. 15 to 17 differs from the one shown in FIGS. 1 to 3 only in the fact that the metal base 2 and the plastic tibia plate 3 respectively comprise a cutout 4 and 38 for the passage of the posterior cruciate ligament.
  • Quite obviously, the prosthesis [0094] 1 shown in FIGS. 15 to 17 works in the same way as the one described in FIGS. 1 to 3.
  • FIG. 18 shows the knee prosthesis [0095] 1 equipped with its metal base 2 and with its tibia plate 3. The metal base 2 comprises, on its horizontal disk 20, and more specifically on the opposite side to the anchoring rod 21, an upstand 5 in the shape of an arc of a circle and of variable height. This upstand has a profile which differs from those that make up the upstands described earlier. At the center of rotation C of the upstand 5 there is a second upstand 6 in the shape of an arc of a circle.
  • The upstands [0096] 5 and 6 engage in housings, not depicted, but formed on the face 30 of the tibia plate 3 to allow the said plate to be guided as it slides in rotation about the center of rotation C, as depicted by the arrow F5.
  • The upstand [0097] 5, in the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medic-lateral direction.
  • The upstand [0098] 6 constitutes a guide means that is in addition to the guide means formed by the upstand 5. Thus, the upstand 6 is positioned on the center of rotation C of the tibia plate 3 on the metal base 2.
  • Provision may be made for the center of rotation of the upstands [0099] 5 and 6 to be offset from the tibia bone vertical axis YY′ without this in any way altering the subject of the invention.
  • FIGS. [0100] 19 to 21 depict an alternative form of the knee prosthesis 1 shown in FIG. 18, namely wherein the upstand 6 is integral with a flange 60 forming a kind of small plate set out in a horizontal plane parallel to the plane containing the disk 20 of the metal base 2.
  • The tibia plate [0101] 3 has, on its face 30, housings 7 and 8 intended to receive respectively the upstands 5 and 6 to allow the tibia plate 3 to slide in rotation over the metal base 2 about the center of rotation C and in the direction of the arrow F5.
  • The housing [0102] 7 has a profile essentially identical to that of the upstand 5, and at the very least, in the shape of an arc of a circle for guiding the tibia plate 3 in its travel.
  • The housing [0103] 8 has a profile essentially identical to the flange 60 of the additional guide means or upstand 6 for guiding the tibia plate 3 in its travel.
  • The housing [0104] 8 is pierced with an internal slot 80 intended to receive the flange 60 of the upstand 6 to achieve a kind of snap-fastening of the tibia plate 3 to the base 2, so that the said plate cannot lift under a tensile force.
  • Note that the upstands [0105] 5 and 6 in the shape of an arc of a circle are curved in the same direction and about the same center of rotation C or C′ when the latter is offset from the tibia bone vertical axis YY′.
  • As in FIG. 15, the metal base [0106] 2 and the tibia plate 3 may respectively comprise cutouts 4 and 38 for the passage of the posterior cruciate ligament.
  • In FIGS. [0107] 22 to 24 the knee prosthesis 1 comprises, on its metal base 2, a first upstand 5′ set out at the external periphery of the horizontal disk 20. Opposite the upstand 5′ the horizontal disk 20 is secured to another upstand 9 in the shape of an arc of a circle, but the radius of curvature of which is inverted compared with that of the upstand 5′.
  • The upstand [0108] 5, which is in the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • The upstand [0109] 9 constitutes a guide means that is in addition to the guide means formed by the upstand 5′. Thus, the upstand 9 is positioned on the center of rotation C of the tibia plate 3 on the metal base 2.
  • The upstand [0110] 9 has the same center of rotation C as the upstand 5′, but the said center may be offset, depending on the configuration of the knee prosthesis, from the tibia bone vertical axis YY′.
  • The upstand [0111] 9 is integral with a flange 90, the function of which will be seen more clearly later.
  • The tibia plate [0112] 3 has, on its lower periphery, that is to say the one that lies between the faces 30 and 31, a recess 10 receiving the upstand 5′ when the tibia plate 3 is fitted onto the metal base 2.
  • On the opposite side to the recess [0113] 10, the lower face 30 is pierced with a housing 12 into which the upstand 9 can be snap-fastened to, on the one hand, guide the plate 3 as it slides in rotation about its center C, and, on the other hand, retain the said plate to prevent it from lifting off the metal base 2.
  • In FIGS. [0114] 25 to 27 the knee prosthesis 1 comprises the metal base 2, the horizontal disk 20 of which has, on its external periphery, an upstand 13 in the shape of an arc of a circle integral with a flange 14 directed toward the tibia bone vertical axis YY′.
  • The horizontal disk [0115] 20 is pierced at the center of rotation C of the upstand 13 with a dish-shaped housing which constitutes a guide means that is in addition to the guide means formed by the said upstand 13. This upstand, which is in the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • The upstand [0116] 13 and the housing 15 may comprise a center of rotation C which is offset from the tibia bone vertical axis YY′.
  • On its external periphery and between the faces [0117] 30 and 31, the tibia plate 3 has a recess 10′ in which there is formed a horizontal slot 16 intended to receive the flange 14 of the upstand 13 as the plate 3 slides in rotation over the metal base 2.
  • The lower face [0118] 30 is integral with a stub 17 with a conical tapering profile capable of engaging with the housing 15 formed in the horizontal disk 20 of the metal base 2.
  • The upstand [0119] 13 equipped with its flange 14, the housing 15, the recess 10′ and its slot 16, and the stub 17 constitute the means of guiding the tibia plate 3 over the metal base 2 as the said plate slides in rotation in the direction of the arrow F5.
  • In FIGS. 28 and 29, the metal base [0120] 2 of the knee prosthesis 1 comprises, on its horizontal disk 20, three peripheral upstands 50, 51 and 52 extending vertically above the said horizontal disk 20.
  • The tibia plate [0121] 3 comprises, on its external periphery, three peripheral recesses 53, 54 and 55 which are intended to receive the upstands 50, 51 and 52 respectively to allow the said plate to be guided as it slides in rotation about the center of rotation of the said upstands, which is identical for all three.
  • The upstand [0122] 51, which is the shape of an arc of a circle or curved, is positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • The upstands [0123] 50, 52 in the shape of an arc of a circle constitute guide means which are in addition to the guide means formed by the upstand 51. The upstands 50, 52 are positioned near the center of rotation C of the tibia plate 3 on the metal base 2.
  • In FIGS. [0124] 30 to 32, the metal base 2 of the knee prosthesis 1 comprises, on its horizontal disk 20, vertical pegs 18 set out in an arc of a circle about a center of rotation C which may be either borne by or offset from the tibia bone vertical axis YY′.
  • The pegs [0125] 18 set out in an arc of a circle are positioned in the anterior part of the metal base 2 and oriented in a substantially medio-lateral direction.
  • In this example, the tibia plate [0126] 3 is identical to the one described in FIGS. 1 to 3, that is to say that its lower face 30 has a housing 34 intended to receive the pegs 18 for guiding the said plate as it slides in rotation with respect to the metal base 2.
  • It can be seen that in each example described hereinabove it is possible, as the case may be, for the center of rotation of the upstands or of the pegs either to be offset or not to be offset in order to determine a particular rotational sliding of the tibia plate [0127] 3 with respect to the metal base 2.
  • Note too that in each example described hereinabove, cutouts [0128] 4 and 38 may or may not be provided for the passage of the posterior cruciate ligament.
  • Furthermore, it can be seen that the guide means in each example described hereinabove are positioned a certain distance away from the center of rotation C, C′. [0129]
  • It will be observed that the short height of the upstand or of the pegs, and its anterior position on the metal base [0130] 2 allows the plastic plate 3 to be fitted onto the said base easily using a strictly anterior approach, the plate requiring upward clearance only by the height of the said upstand or of the said pegs as shown in FIG. 21.
  • It will furthermore be observed that the plastic plate [0131] 3 cannot slide in rotation over the metal base 2 except within the limits set by the difference in dimensions between the housing and the corresponding upstand or peg, and this prevents any undesired excess movement.
  • This being so, it will be readily understood that a plastic plate [0132] 3 can be obtained in which the dimensions of the housing are identical to those of the upstand or of the corresponding pegs, so as to prevent any travel of the said plate over the metal base 2. This allows the surgeon, according to the particular surgical case, to return to a knee prosthesis system with plastic plate which is fixed to the metal base 2, without having to change the latter.
