  • Patent number: 11547570
    Abstract: According to one example, a system for a knee arthroplasty that can optionally comprise: a femoral prosthesis having a joint facing surface and an opposing bone facing surface, wherein the femoral prosthesis has one or more attachment elements at or adjacent the bone facing surface; and one or more features selectively attachable with the femoral prosthesis via the one or more attachment elements, wherein the one or more features comprise one of a box, a stem, or a combination of the box and the stem.

  • Publication number: 20220125593
    Abstract: An orthopaedic knee prosthesis includes a femoral component which exhibits enhanced articular features, minimizes removal of healthy bone stock from the distal femur, and minimizes the impact of the prosthesis on adjacent soft tissues of the knee.
    Type: Application

  • Patent number: 10828176
    Abstract: An orthopaedic implant system includes a set of provisional orthopaedic implants having different implant sizes, in which each provisional implant facilitates an in selection of the next-smallest implant size without removing the provisional implant from the bone. All of the implant sizes share a common sagittal configuration of distal and anterior bone contacting surfaces, but have variable sagittal configurations only in the posterior bone contacting surfaces. Thus, where a relatively larger femoral provisional component is mounted to a femur, changing to a smaller provisional component (i.e., “downsizing”) can be accomplished by recutting only two of live original femoral cuts. Cut slots provided in each provisional implant are sized and positioned to correspond to the posterior bone contacting surface geometry of the next-smallest provisional implant size.

  • Patent number: 10166121
    Abstract: An orthopedic implant system includes a set of provisional orthopedic implants having different implant sizes, in which each provisional implant facilitates an intraoperative selection of the next-smallest implant size without removing the provisional implant from the bone. All of the implant sizes share a common sagittal configuration of distal and anterior bone contacting surfaces, but have variable sagittal configurations only in the posterior bone contacting surfaces. Thus, where a relatively larger femoral provisional component is mounted to a femur, changing to a smaller provisional component (i.e., “downsizing”) can be accomplished by recutting only two of five original femoral cuts. Cut slots provided in each provisional implant are sized and positioned to correspond to the posterior bone contacting surface geometry of the next-smallest provisional implant size.
