  • Publication number: 20190388078
    Abstract: A joint distraction lever for use during a distraction procedure is disclosed. The joint distraction lever includes a lever body having a handle portion coupled to a working portion, a fulcrum extending from a bottom surface of the working portion of the lever body, a distal tip, wherein the distal tip is raised above a top surface of the working portion of the lever body, a force measurement device configured to measure a distraction force applied at the distal tip during a distraction procedure for a joint during which a torque is applied at the handle portion of the lever body, and a force value output configured to indicate the distraction force applied at the distal tip.

  • Patent number: 10219908
    Abstract: A femoral prosthetic component includes a patellar guide portion, a pair of condyles projecting from the guide portion and forming an intercondylar notch therebetween, a bearing surface, and an interface surface configured to face a resected surface of a femur. The interface surface comprises an anterior face and a posterior face, and is substantially contoured between the anterior and posterior face to match a contoured surface of the femur. The substantially contoured interface surface may include at least one planar surface portion to abut a flat cut portion in the surface of the femur. This planar surface portion may be a distal flat at a distal face of the interface surface. The contoured interface surface may alternatively include a plurality of planar surface portions. The femoral prosthetic component is configured such that preparation of the bone to match the interface surface results in minimal resection of the distal femur.

  • Publication number: 20170333051
    Abstract: A method of preparing a tibia to receive a tibial implant component includes performing a first set of cuts to prepare a floor interface surface on the tibia, wherein the floor interface surface includes a portion on each side of a tibial eminence extending above the floor interface surface on the tibia. The method further includes performing a second set of cuts to prepare a tibial eminence wall interface surface, wherein the wall interface surface extends substantially perpendicular to the floor interface surface between the floor interface surface and a top surface of the tibial eminence. The method further includes performing a third set of cuts to prepare a radiused intersection between the floor interface surface and the wall interface surface. The sets of cuts are performed subject to a cutting restraint guide. At least one set of cuts may be performed using a rotary cutter.

The interface surface comprises an anterior face and a posterior face, and is substantially contoured between the anterior and posterior face to match a contoured surface of the femur. The substantially contoured interface surface may include at least one planar surface portion to about a flat cut portion in the surface of the femur. This planar surface portion may be a distal flat at a distal face of the interface surface. The contoured interface surface may alternatively include a plurality of planar surface portions. The femoral prosthetic component is configured such that preparation of the bone to match the interface surface results in minimal resection of the distal femur.

  • Publication number: 20080058951
    Abstract: A proximal femoral ball assembly having a variable offset that is selectively adjustable to conform to various anatomical conditions encountered during a femoral surgical procedure. The femoral ball assembly generally includes a head, a neck, and an adjustment mechanism. The head has a smooth spherical outer surface that is adapted to engage an acetabular component or native acetabulum. The neck extends outward from the head and removeably connects to the head using a threaded attachment.
