  • Patent number: 12232815
    Abstract: Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis, and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient such that a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

  • Patent number: 8857440
    Abstract: A tissue protector is adapted to be positioned on the skin surrounding an incision. The tissue protector provides a load bearing surface for surgical tools and instruments to prevent blunt force and pressure trauma to the skin and soft tissues within the incision. In one embodiment, the tissue protector is a sheet of wear-resistant material having an opening corresponding to the incision and expandable as the incision is retracted. In another embodiment, a tissue protector device includes a continuous expandable arrangement of interconnected L-shaped links. In still another embodiment, a one-piece tissue protector includes a flexible panel supported on the skin and a flexible sleeve extending into the incision. Yet another embodiment of the invention resides in a track that is supported about the incision. An instrument support platform is slidably mounted to the track to support a surgical tool relative to the incision.
