A femoral assembly includes a femoral component that includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral component for articulating with a tibial prosthesis and an inner bone facing side opposite the outer side. The inner bone facing side defines five intersecting component inner surfaces that each extend from a lateral side of the femoral component to a medial side thereof. A femoral augment includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral augment comprised of five intersecting augment outer surfaces and an inner side comprising no more than three intersecting augment inner surfaces. The augment outer surfaces correspond to the component inner surfaces of the femoral component. The augment inner surfaces correspond to resected surfaces of a distal femur.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.

A semi-condylar artificial knee joint includes a femoral prosthesis and a tibial prosthesis, and the cross-section of the tibial prosthesis is of a kidney-like type. The tibial prosthesis is disposed at one side of the tibial plateau intercondylar eminence and is located below the femoral prosthesis. The artificial knee joint further includes a locating pin for fixing the tibial prosthesis. The bottom surface of the tibial prosthesis is provided with a prosthetic notch, and below the tibial prosthesis is provided with a tibial notch. The prosthetic notch corresponds to the tibial notch, and together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the tibial prosthesis and the tibial plateau intercondylar eminence.

A knee joint prosthesis is capable of moving between an extended position and a flexion position. The knee joint prosthesis includes a femoral component that is configured to be mounted to a femur, a tibial component that is configured to be mounted to a tibia, a post fixedly connected to one of the femoral component and the tibial component, and a cam recess defined on the other of the femoral component and the tibial component that is configured to be engaged by the post in either the extended position or the flexion position of the knee joint prosthesis. The knee joint prosthesis may also include an artificial ligament that extends between the femoral component and the tibial component. The post and the ligament mimic one of the ACL and PCL.

A medical device for creating an artificial knee joint or an artificial cruciate ligament in a mammal patient, the medical device comprising a transversal member adapted to be placed through at least three layers of cortical bone of the distal portion of the femoral bone, out of totally four cortical layers along a prolongation of the transversal member. The transversal member is adapted to be involved in the artificial knee joint or the artificial cruciate ligament, wherein the transversal member comprises at least one fixation portion adapted to be involved in fixation of the transversal member to at least one of the at least four layers of femoral cortical bone.

An orthopedic knee prosthesis includes a femoral component, a tibial bearing, a tibial component, a first magnetic portion associated with the femoral component and including a first pole having a first pole polarity the first magnetic portion not physically interrupting any articulating portion of the curved medial condyle surface or curved lateral condyle surface, and a second magnetic portion associated with one or both of the tibial bearing and/or the tibial component and including a second pole having a second pole polarity, the second pole polarity the same as the first pole polarity, the second magnetic portion not physically interrupting any articulating portion of the concave medial bearing surface or concave lateral bearing surface, wherein the first pole and the second pole are in sufficient proximity to each other such that a magnetic repulsive force is present therebetween.

Total knee replacement is the standard treatment for advanced knee osteoarthritis. An improved method of treating an osteochondral defect for knee osteoarthritis of dogs is provided, which is a composite tissue for treating or preventing disease, disorder, or condition associated with an osteochondral defect with new technique. The new technique of custom made instruments and implants for dog and small animals is applied for different breeds of dogs regardless of their sizes and weights. The tool is a custom made instrument, which is based on capture of image based (CT of computed X-ray) to be transferred to electronic 3D model and apply 3D preoperative planning to design the tools are used to perform the knee surgery.

A prosthetic total knee replacement system comprises a distal femoral implant component, a tibial tray implant component and a fixed bearing tibial tray insert. The fixed bearing tibial tray insert is fixed to the tibial tray and articulates with the distal femoral implant component. The fixed bearing tibial tray insert component has a medial-lateral centerline and a stabilizing post. The stabilizing post has a medial-lateral centerline offset laterally from the medial-lateral centerline of the fixed bearing tibial tray insert.
