摘要： A femoral implant for articulation with a patella or a patellar implant includes a body having an articular surface defining a trochlear groove. The trochlear groove is defined by a first trochlear radius at a first location along the trochlear groove and by a second trochlear radius at a second location along the trochlear groove, the first radius being different than the second radius. The configuration of the trochlear groove is such that it narrows as a patella or patellar implant moves from an extension configuration to a flexion configuration. A kit includes the femoral implant along with a patellar implant. A method of trialing involves use of the femoral implant or kit to ensure a smooth transition of the patella or the patellar implant from the femoral component to the adjacent bone.

摘要： In a total ankle replacement joint, tibial and talar components are coupled by first and second tension members threaded through the tibial component and the talar component to support the tibial component relative to the talar component. The total ankle replacement joint is configured such that the tibial component rocks relative to the talar component on fixed-length web member segments of the first and second tension members and fixed-length loop member segments of the first and second tension members constrain motion of the tibial component relative to the talar component.

摘要： A femoral component having a modular stem is discussed. While the femoral component can have any suitable characteristic, in some cases, it includes an external articular surface and an internal surface. While the stem can have any characteristic, in some cases, it includes a proximal end and a distal end. Although the femoral component and stem can attach to a femur in any suitable manner, in some cases, the stem is inserted into the femur's intramedullary canal. In some cases, the femoral component is then: slid onto a resectioned portion of the femur at an angle between 20 and 80 degrees with respect to a longitudinal axis of the femur's distal portion, by rolling the femoral component onto the resectioned portion, or in any other suitable manner. In some cases, the distal end of the stem is then permanently fixed to the femoral component's internal surface. Other implementations are described.

摘要： A prosthetic femoral component (10) for an orthopedic prosthesis has a canted patellar groove adapted for optimal patella/component interaction, with the component configured to have a medial or lateral cant depending upon the method of implantation. The femoral component defines a distal “component transverse plane,” which is a plane tangent to the distal-most points of the component condyles (12, 14). In a “mechanical” implantation, the component transverse plane is substantially normal to the mechanical femoral axis of the femur after the component has been implanted. Where the femoral component is configured to be “mechanically oriented” in this manner, the component has a medially canted patellar groove. On the other hand, an “anatomic” implantation is one in which, after the component has been implanted, the component transverse plane is substantially parallel to an “anatomic” transverse plane. The anatomic transverse plane is perpendicular to the anatomic axis of the femur from a sagittal view, and is inclusive of a line connecting the distal-most points of the natural femoral condyles before resection. Where the femoral component is configured to be “anatomically oriented” in this way, the component has a non-canted or slightly laterally canted patellar groove.

摘要： Implant includes a body and a utile feature, for example, a smooth articulating surface. A transverse rail stem system with a plurality of rails is provided, spaced apart from the utile feature, which is adapted for transverse insertion into a bodily substrate, for example, resected bone. A surgical template—for example, to assist in sawing, drilling with a drill bit and drill guide, and broaching with a broach—along with such bone removal tools can help prepare the bone for receipt of the implant.

摘要： A system for replacing a trochlear groove region of a femur. The system includes a prosthesis that includes a bone contact surface and a periphery that defines an outer perimeter. The bone contact surface has a plurality of protrusions and a spatial configuration with respect to one another. Additionally, the system includes a first template that has a plurality of guide holes and a first periphery that defines an outer perimeter that substantially corresponds with the periphery of the prosthesis. Also, included in the system is a second template that has a plurality of guide holes and a second periphery that defines an outer perimeter that substantially corresponds with the periphery of the prosthesis. The plurality of guide holes of the second template are spatially arranged with respect to the second periphery to substantially match the spatial configuration of the plurality of protrusions of the prosthesis.

摘要： A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.
