  • Dual stylus variable angle total knee instruments and methods
    Patent number: 11931051
    Abstract: An instrument for setting a position of a resection of a distal femur or a proximal tibia in a total knee arthroplasty, the instrument comprising: a stable portion, the stable portion configured for orientation in a set position relative to said distal femur or said proximal tibia; a resection guide portion, the resection guide portion configured to guide a resection path for said resection; a resection guide body, the resection guide body associated with the resection guide portion in a fixed orientation; the resection guide body pivotally connected to the stable portion, whereby pivoting adjustment of the resection guide body on the stable portion sets a resection orientation of the resection guide portion; and the resection guide body having a lock for selectively locking the resection guide body to the stable portion at a plurality of selectable resection orientations.
