Abstract
Surgical devices and methods of surgical repairs using the devices are disclosed. The device and methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A tensionable knotless fixation device is provided with a tensioning construct (formed of a tensioning strand, a tensionable, adjustable, knotless, self-cinching loop, and a splice adjacent the loop) pre-loaded onto a fixation device. A flexible material (for example, suture or suture tape) may be attached to a fixation device. A flexible material may be threaded through an eyelet of a fixation device.
Claims9
A method of knotless tissue repair, comprising:
- inserting a fixation device into a prepared bone hole or opening, the fixation device comprising an anchor body and an anchor tip, the anchor tip being rotatably received within the anchor body upon advancement of the anchor body over a shaft of the anchor tip;
- a tensionable construct pre-loaded onto the fixation device;
- and a flexible material attached to the fixation device, wherein the tensionable construct comprises a flexible strand with a knot and a free end, a tensionable, closed, adjustable, knotless, self-cinching loop, and a splice, and wherein the flexible material has a first limb and a second limb;
- and
- passing the tensionable construct and the flexible material around or through tissue to be fixated or reattached to bone, and positioning the tensionable loop over and above the tissue.
A method of attaching tissue to bone using an anchor assembly including a driver and a fixation device, the fixation device comprising an anchor body and an anchor tip rotatably received within the anchor body upon advancement of the anchor body over a shaft of the anchor tip, the anchor tip being configured to receive a tensionable construct and a separate flexible material for attachment to bone, the tensionable construct comprising a flexible strand with a free end and a knot, a splice, and a tensionable, adjustable, closed, knotless, self-cinching loop having an adjustable perimeter, the method comprising the steps of:
- providing a fixation device pre-loaded with a tensionable construct;
- securing the fixation device pre-loaded with the tensionable construct to a driver;
- threading a flexible material through a closed eyelet of the anchor tip of the fixation device;
- installing the fixation device, pre-loaded with the tensionable construct and with the flexible material, into a bone socket or tunnel using the driver;
- passing the tensionable construct and limbs of the flexible material through tissue, so that the loop of the tensionable construct is positioned above the tissue;
- passing the limbs of the flexible material through the loop;
- pulling on the free end of the tensionable construct to reduce the perimeter of the loop and approximate the tissue to bone;
- and
- securing the limbs of the flexible material with additional fixation devices.
