  • Publication number: 20090149858
    Abstract: A tool and method for drilling a bone for receipt of a first and second bundle includes drilling a first tunnel in the bone. A locating instrument may be positioned into the first bone tunnel thereby defining a reference axis. A tool may be inserted through a portal defined in surrounding tissue. The tool may engage the locating instrument thereby identifying a relative orientation between the reference axis and the drill axis for preparation of a second bone tunnel. The second bone tunnel may be drilled along the drill axis.

  • Publication number: 20090082805
    Abstract: Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. At least one adjustable loop of a flexible construct is passed through the soft tissue. The at least one adjustable loop is passed through a passage construct. A locking member is passed through the at least one adjustable loop and the adjustable loop is reduced about or within the locking member such that the at least one loop is frictionally retained in the passage construct and locked in place by the locking member to thereby secure the soft tissue.

  • Patent number: 7500983
    Abstract: An apparatus and method for fixing a selected graft relative to a selected anatomical portion. An anchor may be provided that may be interconnected with a selected graft portion that is operable to pass through a selected bore and then moved into an operable position to engage a selected portion of the bore to substantially eliminate the possibility of the graft moving in an unselected direction through the bore. In addition, a spacer member may be used to expand a selected portion of the graft to reduce localized stress and may increase ingrowth into a selected bony portion.

  • Publication number: 20080255613
    Abstract: Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. An adjustable loop region of a flexible construct contained in a bore defined by a fastener is passed through a tissue. The adjustable loop is passed through the tissue. The fastener is passed back through the adjustable loop to fold the adjustable loop upon itself. The fastener is attached to the bone. An adjusting arm on the flexible construct is engaged to reduce the size of the adjustable loop and secure the soft tissue to the bone.

  • Patent number: 7255700
    Abstract: A device and method for fastening one or more graft strands to a bone. The device may include a first member having a first opening and a second member having a second opening. The first member may include a plurality of radial projections defining recesses, wherein each graft is separately received in a corresponding recess. The device may also include a fastener passing through the first and second openings. The fastener may have a first portion engaging the first member and a second portion received into the bone, such that tightening the fastener against the first member compresses the graft strands between opposing faces of the first and second members.
