Suture anchor and methods of knotless tissue fixation

摘要

Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices and loops having attached flexible materials that are pre-loaded onto modified knotless anchors (for example, swivel and/or screw-in suture anchors and/or push-in suture anchors with a distal eyelet) to position the self-locking, adjustable construct at the repair site. The systems allow for knotless tensioning of the tissue after the knotless anchors have been implanted.

主权项

1. A method of tissue repair, comprising the steps of: providing a surgical device comprising a fixation device and a flexible construct extending through the fixation device, the flexible construct comprising a flexible strand with a splice formed within the flexible strand, an adjustable loop having an adjustable perimeter, a free end, a fixed end, and a flexible material attached to the adjustable loop;
installing the fixation device into a first tissue; passing the flexible strand with the attached flexible material through a second tissue after installing the fixation device into the first tissue to secure the flexible material to the second tissue; pulling on the free end to bunch up the flexible material and provide tensioning of the second tissue relative to the first tissue; and subsequently reducing a distance between the first and second tissues.
