  • Modified intervastus arthrotomy closure method
    Patent number: 11553910
    Abstract: A method for arthrotomy closure includes using a first sutured needle to form a first series of parallel stitches from a caudal end of the arthrotomy incision to a first point spaced from the cephalad end of the arthrotomy incision, using a second sutured needle to form a second series of parallel stitches from a cephalad end of the arthrotomy incision to the caudal end of the arthrotomy incision. The second series of stitches intersect the first series of stitches at a 45 degree angle after passing the first point. After the second series of stitches is formed, the first sutured needle is used to form a third series of stitches from the first point to the cephalad end of the arthrotomy incision. The third series of stitches are parallel to the first series of stitches and intersect the second series of stitches at a 45 degree angle.
