  • Patent number: 9060868
    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: Grant
    Filed: April 27, 2012
    Date of Patent: June 23, 2015
    Assignee: Zimmer, Inc.
    Inventors: Raymond C. Parisi, Nick Drury, Charles A. Baldridge
  • Patent number: 9011453
    Abstract: An orthopaedic implant system includes a set of provisional orthopaedic implants having different implant sizes. 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, so that the cut slots can be used to further resect posterior femoral surfaces to accept the next-smallest implant component size.

  • Publication number: 20080097450
    Abstract: A patella clamp is provided for clamping a patella. The patella clamp includes a first clamp member engageable with the patella and a second clamp member mountable in opposing relative moving relationship to the first clamp member. The patella clamp may be used to perform a variety of procedures on a patella. In one embodiment, a third clamp member is alternatively mountable in place of the second clamp member to change the function of the patella clamp. The patella clamp optionally further includes a cut guide for guiding a cutter in a cut plane to resect a portion of the patella.
