Definitions
- This invention relates generally to prosthetic implants and, more particularly, to devices of this type including contained, compressible, resilient members.
- TKRs total knee replacements
- polyethylene trays are placed between metal tibial and femoral components.
- the metal femoral component articulates with the polyethylene tray.
- the loads across the TKR and movement between the femoral component and poly tray cause surface wear of the poly.
- the problems associated with poly wear are well known to Orthopaedic surgeons: fracture of the poly tray, thinning of the tray, migration of poly particles throughout the body, and loosening of the prosthetic joint from the body's reaction to the poly particles.
- U.S. Pat. No. 6,302,916 describes many of these problems.
- Metal-on-metal articulations are seen as an improvement over metal on poly articulations. Metal on metal articulations are reported to have 400 ⁇ less wear than metal on poly surfaces, but their use has so far been limited.
- Cartilage surfaces have a very low coefficient of friction.
- Metal-on-metal surfaces and metal-on-poly surfaces also have low coefficients of friction.
- Cartilage also provides cushioning or dampening of forces across the joint.
- Metal-on-metal designs do not provide dampening.
- Metal-on-poly surfaces provide more dampening than metal on metal surfaces, but they do not the cushioning of cartilage.
- the choice of materials for prosthetic implants is also limited by surface wear characteristics of the materials. Metals have better surface wear characteristics than polyethylene, but metals do not provide cushioning. The choice of materials is also limited by the tensile strength of the materials. Materials used to form articular surfaces must withstand the large forces exerted on the joint. The materials must withstand shear and tension forces in addition to compression forces. Polyethylene was chosen as the best material to meet the requirement listed above.
- this invention encases, encapsulates, contains, or otherwise protects a compressible/resilient member with one or more rigid components associated with an articulating bone.
- the embodiments are applicable not only to artificial disc replacement (ADR) devices, but also to joint situations including the knee, hip, elbow, shoulder, wrist, and ankle.
- ADR artificial disc replacement
- the cushion elements in the preferred embodiments include synthetic rubbers, hydrogels, elastomers, and other polymeric materials such as viscoelastic polymers and foam polyurethanes.
- the invention effectively combines the advantages of such materials (cushioning, shape memory, and expansion after insertion in the case of hydrogels), while providing increased protection, particularly the elimination of shear stresses.
- a cushion element provides better wear characteristics than polyethylene (“poly”) alone. Since a metal-on-metal, metal-on-ceramic, or ceramic-on-ceramic articulating surface has better wear characteristics than metal on poly, the invention essentially provides cushioning for metal/ceramic-on-metal/ceramic joint replacements. It also allows the use of elastomers for their cushioning properties rather than their surface wear and tensile strength characteristics.
- the contained compressible elements could also be used as a cushion below polyethylene components, polyethylene over metal components, unicondylar knee replacements, patellar components, and prosthetic components for other parts of the body. All of the embodiments of the invention can be enclosed by a membrane to trap wear debris inside the device.
- the seal can also hold a lubricating fluid, such as vegetable oil or other oils or gels inside the device. In hydrogel embodiments, the seal can be fluid permeable.

- the invention When applied to an ADR, the invention also minimizes the risk of extrusion.
- Hydrogels are used in the preferred embodiments.
- the small size of the desiccated hydrogel facilitates insertion, after which the hydrogel imbibes fluids and expands.
- Other non-hydrogel compressible and/or resilient materials may alternatively be used, including elastomers, shape-memory polymers, which would increase in height after they are inserted.
- non-hydrogel polymers such as acrylics may be used which change shape with a change in temperature.
- the term “hydrogel” should be taken to include other resilient/compressible materials.
- the hydrogels are protected from shear stress, thereby extending longevity.
- the hydrogel is contained, constrained or enclosed within a cavity or cylinder which may include one or more pistons.
- the hydrogel provides cushioning, while the metal pistons facilitate articulation either directly or indirectly with bone surfaces.
- the invention offers the advantages of metal-on-metal while providing for cushioning.
- the hydrogels allow for physiologic tension adjustment since they can change size based upon imbibing fluid and the pressure on the hydrogel.
- the hydrogel component of the device can change height to balance the forces against the surrounding tissues.
- the cylinder and piston would likely be made of metal such as stainless steel, titanium, chrome cobalt, or other biocompatible metal or ceramic alloy. Surfaces to promote bone ingrowth could be used on the covers.
- the hydrogel embodiments may incorporate channels for the diffusion of fluids in and out of the cylinder.
- Optional permeable membranes can also be used to prevent extrusion of the hydrogel through the channels. The permeable membrane traps the hydrogel but allows fluids to move freely across the membrane.

Abstract
In a total knee replacement (TKR), the use of a cushion element provides better wear characteristics than polyethylene (“poly”) alone. Since a metal-on-metal, metal-on-ceramic, or ceramic-on-ceramic articulating surface has better wear characteristics than metal on poly, the invention essentially provides cushioning for metal/ceramic-on-metal/ceramic joint replacements. It also allows the use of elastomers for their cushioning properties rather than their surface wear and tensile strength characteristics. The contained compressible elements could also be used as a cushion below polyethylene components, polyethylene over metal components, unicondylar knee replacements, patellar components, and prosthetic components for other parts of the body, including the hip, elbow, shoulder, wrist, and ankle.

- This application claims priority from U.S. Provisional Patent Application Ser. Nos. 60/379,462, filed May 10, 2002; 60/445,489, filed Feb. 6, 2003; and 60/445,958, filed Feb. 7, 2003.

No. 10/303,385, filed Nov. 25, 2002; which is a continuation-in-part of U.S. patent application Ser. No. 10/191,639, filed Jul. 9, 2002 and Ser. No. 09/415,382, filed Oct. 8, 1999, now U.S. Pat. No. 6,419,704. The entire content of each application and patent is incorporated herein by reference.
- This invention relates generally to prosthetic implants and, more particularly, to devices of this type including contained, compressible, resilient members.
- In prior art total knee replacements (TKRs), polyethylene trays are placed between metal tibial and femoral components. The metal femoral component articulates with the polyethylene tray. The loads across the TKR and movement between the femoral component and poly tray cause surface wear of the poly. The problems associated with poly wear are well known to Orthopaedic surgeons: fracture of the poly tray, thinning of the tray, migration of poly particles throughout the body, and loosening of the prosthetic joint from the body's reaction to the poly particles. U.S. Pat. No. 6,302,916 describes many of these problems.
- Metal-on-metal articulations are seen as an improvement over metal on poly articulations. Metal on metal articulations are reported to have 400× less wear than metal on poly surfaces, but their use has so far been limited.
- Surgeons who perform arthroplasty of arthritic joints hope to eliminate pain and restore normal function of the replaced joint. Arthroplasty surface technology attempts to replicate cartilage function. Cartilage surfaces have a very low coefficient of friction. Metal-on-metal surfaces and metal-on-poly surfaces also have low coefficients of friction. Cartilage also provides cushioning or dampening of forces across the joint. Metal-on-metal designs do not provide dampening. Metal-on-poly surfaces provide more dampening than metal on metal surfaces, but they do not the cushioning of cartilage.
- The choice of materials for prosthetic implants is also limited by surface wear characteristics of the materials. Metals have better surface wear characteristics than polyethylene, but metals do not provide cushioning. The choice of materials is also limited by the tensile strength of the materials. Materials used to form articular surfaces must withstand the large forces exerted on the joint. The materials must withstand shear and tension forces in addition to compression forces. Polyethylene was chosen as the best material to meet the requirement listed above.
- In broad and general terms, this invention encases, encapsulates, contains, or otherwise protects a compressible/resilient member with one or more rigid components associated with an articulating bone. The embodiments are applicable not only to artificial disc replacement (ADR) devices, but also to joint situations including the knee, hip, elbow, shoulder, wrist, and ankle.
- The cushion elements in the preferred embodiments include synthetic rubbers, hydrogels, elastomers, and other polymeric materials such as viscoelastic polymers and foam polyurethanes. The invention effectively combines the advantages of such materials (cushioning, shape memory, and expansion after insertion in the case of hydrogels), while providing increased protection, particularly the elimination of shear stresses.
- In a total knee replacement (TKR), the use of a cushion element provides better wear characteristics than polyethylene (“poly”) alone. Since a metal-on-metal, metal-on-ceramic, or ceramic-on-ceramic articulating surface has better wear characteristics than metal on poly, the invention essentially provides cushioning for metal/ceramic-on-metal/ceramic joint replacements. It also allows the use of elastomers for their cushioning properties rather than their surface wear and tensile strength characteristics.
- The contained compressible elements could also be used as a cushion below polyethylene components, polyethylene over metal components, unicondylar knee replacements, patellar components, and prosthetic components for other parts of the body. All of the embodiments of the invention can be enclosed by a membrane to trap wear debris inside the device. The seal can also hold a lubricating fluid, such as vegetable oil or other oils or gels inside the device. In hydrogel embodiments, the seal can be fluid permeable.

FIG. 27 is a sagittal cross section of another embodiment of the invention. - This invention address and solves such problems arising in the prior art. The embodiments are applicable not only to ADR devices, but also to joint situations including total knee and hip arthroplasty. The approach effectively combines the advantages of hydrogels (cushioning, shape memory, and expansion after insertion) and rubber or other elastomers (cushioning), while eliminating shear stresses on the polymer. When applied to an ADR, the invention also minimizes the risk of extrusion.
- Hydrogels are used in the preferred embodiments. U.S. Pat. Nos. 5,047,055 and 5,192,326 both incorporated by reference, list some of the applicable hydrogels. The small size of the desiccated hydrogel facilitates insertion, after which the hydrogel imbibes fluids and expands. Other non-hydrogel compressible and/or resilient materials may alternatively be used, including elastomers, shape-memory polymers, which would increase in height after they are inserted. As another example of many, non-hydrogel polymers such as acrylics may be used which change shape with a change in temperature. Thus, as used herein, the term “hydrogel” should be taken to include other resilient/compressible materials.
- According to the invention, the hydrogels are protected from shear stress, thereby extending longevity. In particular, the hydrogel is contained, constrained or enclosed within a cavity or cylinder which may include one or more pistons. The hydrogel provides cushioning, while the metal pistons facilitate articulation either directly or indirectly with bone surfaces. Thus, the invention offers the advantages of metal-on-metal while providing for cushioning. The hydrogels allow for physiologic tension adjustment since they can change size based upon imbibing fluid and the pressure on the hydrogel. Thus, the hydrogel component of the device can change height to balance the forces against the surrounding tissues.
- The cylinder and piston would likely be made of metal such as stainless steel, titanium, chrome cobalt, or other biocompatible metal or ceramic alloy. Surfaces to promote bone ingrowth could be used on the covers. The hydrogel embodiments may incorporate channels for the diffusion of fluids in and out of the cylinder. Optional permeable membranes can also be used to prevent extrusion of the hydrogel through the channels. The permeable membrane traps the hydrogel but allows fluids to move freely across the membrane.
