Definitions
- Joint implant especially the knee joint.
- the invention relates to a joint implant, especially the the knee joint, comprising a femoral component, an insert and a tibial component.
- a joint can be exemplified by the physiological movement in the knee joint, which is a complex combination of rolling, rotary and sliding movements.
- the burden on the joint while walking on a flat surface is a multiple of the body weight; in case of climbing stairs, walking uphill and carrying heavy loads, the burden is even higher.
- a known total knee replacement is an assembly comprising primarily three main components, used to renew the natural function of the knee joint.
- the components are: femoral component, insert and tibial component.
- the femoral component is the fundamental segment of the total knee replacement assembly.
- Standard femoral components are currently produced from bio-compatible Cr-Co-Mo or Ti alloys using the methods of casting and chip machining. Femoral components are made in standard sizes so as to suit the biggest range of patients possible.
- the inner shape of the femoral component is composed of five surfaces that ensure a proper seating of the replacement on the distal part of the femur. In most cases, the replacement is fixed with two plugs and bone cement - if a cemented replacement is used. Fixing non-cemented replacements is ensured by the gradual ingrowth of the bone into the porous inner surface of the replacement.
- the disadvantages of these solutions are in particular the relatively large weight and rigidity of the femoral components, determined by the size, shape design and material applied.
- Another disadvantage is the relatively large loss of the patient's bone due to osteotomy and settlement of the implant onto the bone. In this case, once again, it is necessary to repeat the operation after some time, which is accompanied by another loss of the original bone and larger size of the implant .
- Another disadvantage is the method of fixing of the plugs by drilling, which is technologically simple, but does not prevent the replacement from loosening axially.
- a joint implant especially the knee joint, comprising a femoral component, an insert and a tibial component, as specified in this invention.
- the femoral component of the knee joint replacement is composed of a shell mould attachable to the distal part of the femur, where the reference plane determining the outer and inner shape of the mould is a trimmed, spaced and smoothed surface of the distal part of the patient's femur that accounts for the overall curvature of the knee joint.
- the outer lateral and antero-posterior dimensions of the shell mould advantageously match the specific knee joint of the given patient.
- the inner surface of the shell mould is ribbed, where the ribs lock laterally and longitudinally in grooves created operatively in the distal part of the patient's femur.
- the shell mould is advantageously made from a bio-compatible material.
- the joint implant as mentioned above is made so that CT data on the patient's affected knee joint are evaluated and, after these data are edited in a CAx application, an individual 3D model for the shell mould is created.
- the final 3D model is then transformed into a high-resolution STL format and a shell mould is produced, for instance using the additive method of DMLS (Direct Metal Laser Sintering) , where:
- CT - Computed tomography - is a medical imaging technology based on tomography, created using computer equipment and providing a three-dimensional image of the investigated object;
- CAx - Computer-Aided Technologies - is a term that covers broad range of computer applications for designing, analyzin and manufacturing parts;
- STL - Stereolithography - is a format type for storing data on three-dimensional objects and is used in many computer programmes to support the production of parts;
- DMLS - Direct Metal Laser Sintering - is a production method using the technology of continuous sintering of particles using laser.
- the trimmed, spaced and smoothed surface of the distal part of the patient's femur that accounts for the overall curvature of the knee joint is used as the reference surface that determines the outer and inner shape of the shell mould. Outer dimensions are chosen to suit the specific knee joint, individually for each patient. When the thickness of the layer is added to the reference surface, the required shell mould for the knee joint is created. The thickness of the shell mould is chosen to maintain the correct function of the implant .
- Fixation to the knee joint is achieved using a system of ribs, suitably placed laterally and longitudinally on the inner side of the shell mould of the knee replacement.
- the ribs lock into the grooves operatively created in the distal part of the patient's femur.
- the replacement is made, for example using the DMLS additive technology, from a bio-compatible material that features a low specific gravity, a high strength to density ratio and specific tribological properties.
- the subject of the invention is a new type of a shell- moulded joint implant, including the overall design and implementation of its production technology.
- the implant of a shell-moulded type can be used as a replacement in case of cartilage degradation not only in human knee joints.
- the design of the proposed technology consists in obtaining the patient's CT data, their processing and preparation of a model of the required joint. Based on these data, a corresponding joint replacement model is created in a CAx application, and then produced from a bio-compatible alloy using an additive production method.
- a great benefit of this joint replacement type is a smaller intervention in the patient's body, with a reduced resection on the thigh bone, better maintenance of the bone mass, shorter operation time and lower financial costs.
- the femoral component of the shell-moulded implant is made to achieve the same functional parameters as the current batch-produced implants. Compared to current implacts, the shell-moulded implant makes it possible to maintain more of the patient's bone mass, reduce the extent of operation as well as operative and post-operative trauma.
- the main advantage of the shell-moulded implant is its shape, derived from the actual shape of the patient's femur, with a relatively small thickness, thanks to which it is not necessary to perform an extensive resection of the distal part of the femur during the operation, as is the case of commonly used femoral components. Thanks to a system of ribs on the inner surface of the implant, simple fixation and rigidity of the implant are secured.
- the description above also shows that a shell-moulded replacement has a lower weight and in general the operation is much more regardful of the patient.
- CT data on the patient's affected knee joint are enough to create an STL model of the knee joint.
- an individual 3D model of the shell-moulded replacement is created.
- the final 3D model is then transformed into a high-resolution STL format, which will ensure a sufficient quality of the surface of the implant.
- Production as such is carried out from a bio-compatible material using for example the DMLS additive method, one of a group of rapid prototyping technologies. Excellent mechanical properties and corrosion resistance in combination with low specific gravity are typical for this alloy.
- the new type of a shell-moulded implant brings the following advantages: retaining the thigh bone to a much larger extent than until now for the necessary revision operations; maintaining the extent of mobility and anatomical load; reduction of the risk of displacement of the shell- moulded implant; renewal of the natural function of the knee joint using a very durable implant with a long lifecycle; lower production and operating costs due to a lower consumption of materials, reduced time of operation etc., and another advantage is a distinct reduction of the weight of the shell-moulded implant compared to the current implant types as well as a better specific load capacity of the contact surfaces of the implant and the bone. Advantages also include smaller post-operative trauma for patients - shorter treatment time and reduction or elimination of repeated operations and implant replacements.
- FIG. 1 shows an axonometric view of the shell- moulded replacement, implanted on the distal part of the femur.
- Fig. 2 shows an axonometric view of the inner surface of the shell-moulded implant with fixation ribs.
- An embodiment of the knee joint implant comprises a femoral component, a PE insert and a tibial component.
- the femoral component of the knee joint replacement comprises shell mould 1, attachable to the distal part of femur 2.
- the trimmed, spaced and smoothed surface of the distal part of the patient's femur 2 that accounts for the overall curvature of the knee ⁇ joint is used as the reference surface that determines the outer and inner shape of shell mould 1.
- the outer lateral and antero-posterior dimensions of shell 1 match the specific knee joint of the given patient.
- the thickness of shell 1 is chosen to maintain the correct function of the implant.
- the inner surface of shell 1 contains ribs 3, placed laterally and longitudinally, which lock in grooves created operatively in the distal part of the patient's femur 2.
- Shell 1 is made for example from the bio-compatible material T16A14V.
- Shell mould 1 is fixed to the knee joint using a system of ribs 3, which lock into grooves created operatively in the distal part of the patient's femur 2.
- the CT data on the patient's affected knee joint are evaluated.
- an individual 3D model of shell mould 1 is created.
- the final 3D model is then transformed into a high-resolution STL format and shell mould 1 is produced, for instance using the additive method of DMLS .
- the replacement is made from a bio-compatible material that features a low specific gravity, a high strength to density ratio and specific tribological properties.
- a joint implant as specified in this invention can be especially used in medicine - surgery and orthopedics.
