  • Meniscal transplant system
    Patent number: 10736755
    Abstract: A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

  • Locking Suture Construct
    Publication number: 20200214692
    Abstract: A locking suture construct having suture material with a first end and a second end, each attached to a first body in a slidable manner, a constricting member formed in the second end of the suture material, and a bight in the suture material between the first end and the second end. The bight can be pulled through the constricting member around a second body to create a locking loop. The first end and the second end are passed through the locking loop. Pulling the first end increases a perimeter of the locking loop and moves the constricting member toward the second body. When the constricting member reaches the second body, pulling the first end reduces the perimeter of the locking loop and moves/rotates the constricting member around the second body toward the first body to hold the first body in relative position to the second body.
