This disclosure relates to surgical fixation systems and methods. The surgical fixation systems may include one or more loops and one or more reinforcement materials. The surgical fixation systems can be used in various knotless tissue repair procedures.

A ligament fixation method can include forming a bone tunnel to a predetermined depth from a surface of a bone; mounting a reconstruction ligament to the ligament fixation device. The reconstruction ligament can be disposed along outer surfaces of plate-like pressing segments of a ligament fixation device and an outer surface of a connection segment that connects the pressing segments. The method can also include inserting the ligament fixation device into the bone tunnel from the connection-segment side; fastening a screw to a receiving section of the ligament fixation device from an opening of the ligament fixation device to increase a distance between the pair of pressing segments and to compress the reconstruction ligament between each pressing segment and an inner surface of the bone tunnel; and fixing the reconstruction ligament to the bone by causing a part of the screw to dig into the bone.

A ligament fixation device for fixing a ligament to a bone tunnel includes: a fixation device body having a flat surface, wherein the fixation device body has a mounting section for mounting the ligament or a pulling member thereto and a torque application portion configured to apply torque about an axis orthogonal to the flat surface, the pulling member being provided for mounting the ligament, and wherein the mounting section includes a pair of through-holes provided in the noncircular flat surface.

A method of tissue repair that includes installing a surgical construct in a bone hole. The surgical construct has a fixation device that is preloaded with a primary flexible strand. After installing the surgical construct in the bone hole, the method includes coupling at least one secondary flexible strand to the primary flexible strand for subsequent use in repairing the tissue.

A method of reinforcing a biological construct according to an exemplary aspect of the present disclosure includes, among other things, attaching a suture loop/needle construct to a reinforcement material and stitching the reinforcement material to a biological construct to form a reinforced biological construct. The reinforcement material is attached to the suture loop/needle construct prior to approximating the reinforcement material to the biological construct.

An implantable suspension device (1) for fixing an elongated flexible implant (G) or tissue (B) in a desired position, comprising a suspension plate (100) and a single suture element (200) engaging with the suspension plate (100) such that the suture element (200) forms an adjustable suspension loop (300) for connecting said implant (G) or tissue (B) to the suspension plate (100), wherein the single suture element (200) comprises a free first end section (201) and a second end section (202), and wherein the single suture element (200) comprises a stopper (20) arranged on the second end section (202), and wherein the suture element (200) forms a locking loop (40) for pressing the first end section (201) against the suspension plate (100) and thereby locking the first end section (201) of the suture element (200) with respect to the suspension plate (100).

Devices and methods for fixating a graft tendon in a bone tunnel for a ligament reconstruction or repair procedure are provided. In general, the described implantable tissue fixation device includes first and second elongate, substantially rigid support members that are discrete elements separated from each other, and at least one flexible member connecting the rigid support members. The tissue fixation device can have changeable dimensions such that it has at least one dimension that is smaller in a delivery configuration than in a deployed configuration. In both delivery and deployed configurations, the first and second rigid support members are positioned in a non-intersecting orientation with respect to one another. A graft retention loop coupled to the tissue fixation device has the graft tendon coupled thereto and extending into the bone tunnel so as affix the graft into the bone.

Tensionable, knotless, self-locking surgical constructs and methods for surgical repairs are disclosed. A tensionable, knotless, self-locking surgical construct includes two self-locking, tensionable, knotless independent mechanisms loaded onto a fixation device, one of the two self-locking, tensionable, knotless, independent mechanisms including a preformed, flexible, continuous, uninterrupted loop. The fixation device can be a knotless fixation device such as a hard-body anchor, or a knotless soft anchor such as an all-suture knotless anchor.

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical soft tissue repair device includes a snare assembly coupled to a soft anchor in which the soft anchor has a first, unstressed configuration that can be used to insert the anchor into bone and a second, anchoring configuration that can be used to fixate the anchor in the bone. The snare assembly can be configured to actuate the anchor from the first configuration to the second configuration, and it can also be used to engage and approximate tissue by drawing the tissue closer to the anchor fixated in the bone. The snare assembly can be used in conjunction with a number of different anchor configurations, and other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

Disclosed are surgical constructs and methods of use for a one-way adjustable fixation loop that is formed by tying two knots in a surgical filament, each knot defining an individual adjustable loop and the individual adjustable loops being interconnected to form the one-way adjustable fixation loop. The knots enable a non-spliceable suture to be used in the creation of the one-way adjustable fixable loop. Embodiments can include a fixation device, such as a cortical button or plate for use in a bone tunnel, and enable the knots to work independent of and suspended below the fixation device. Embodiments can increase the compatibility of the adjustable fixation loop with existing fixation devices and can isolate and protect the knots from damage during use and after implantation.
