A dynamic ligament repair device includes a suture, a femoral side suture anchor and a threaded screw or housing implant. The screw is configured for placement in the tibia, or alternatively in the femur. A spring is housed inside an axial bore in the threaded screw. In some embodiments, the spring is a compression spring. A moveable spring button is positioned inside the axial bore adjacent a distal end of the spring. The spring button engages the spring directly in some embodiments. In alternative embodiments, an intermediate structure such as a spacer is positioned between the spring button and the spring. The suture extends between the spring button and the suture anchor. When the joint flexes or extends, the spring button travels inside the axial bore and dynamically compresses or relaxes the spring.

A ligament assembly comprising a first ligament anchor (9) connected to a second ligament anchor (14) by a ligament (18) a resilient element (40) being associated with the first ligament anchor (9) and a ligament tension adjuster (44, 50) being associated with the second ligament anchor (14). The resilient element (40) may be disposed within the first ligament anchor (9) and the ligament tension adjuster (44, 50) may be disposed within the second ligament anchor (14).

A surgical device for arthroscopy includes an insertion arm having a folded contact end, a handle connected to a connection end of the insertion arm, opposite to the folded contact end, and extending transversely to the insertion arm, and a retrieval element connected to the insertion arm and mobile along the insertion arm between a retracted position and an extracted position in which it intercepts a leading end of a suture thread at the folded contact end, and mobile between the extracted position and the retracted position in which it holds the leading end. The retrieval element is a basket made of flexible material defining a containment volume for receiving said leading end of the suture thread. The containment volume is configured to expand in the transition between the retracted position and the extracted position and to shrink in the transition between the extracted position and the retracted position.

Tissue fixation and repair constructs and methods of repair using the same are provided. An exemplary tissue fixation and repair construct can include a first implantable anchor coupled to a suture having a fixed tail and a tensioning tail. The fixed tail can include an overhand knot located distally adjacent to the finger trap, such that the overhand knot substantially abuts the finger trap when adjacent thereto, a fixed stopper knot configured to prevent further movement of the fixed tail through a second implantable anchor when the second implantable anchor is placed onto the suture, and a finger trap. The tensioning tail can be passed through the finger trap and overhand knot, and can be used to adjust the tension of the tissue fixation and repair construct when the first implantable anchor and the second implantable anchor are inserted into bone.

An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.

The present disclosure provides a system, method, and cannulated anchor for treating acute or chronic instability of two boney structures in a patient. The provided cannulated anchor includes an opening through which suture, and in some instances a tendon graft, may be positioned. The cannulated anchor also includes a securing mechanism that helps maintain its position when installed in bone, such as flexible prongs, angled tabs, or ridges. The cannulated anchor is installed by being translated over a k-wire with a cannulated inserter that engages the cannulated anchor. The k-wire passes through the tendon graft, if used, as the cannulated anchor is translated over the k-wire. Passing the k-wire through the tendon graft allows the tendon graft to take up more space within the cannulated anchor's opening versus being biased to one side of the k-wire during insertion.

Provided by the present invention is a loop, comprising a fixing plate and a suture, wherein the fixing plate is provided with at least two threading holes, the suture is wound to form a first coil and a second coil, the first coil and the second coil are arranged on a same side of the fixing plate, and two ends of each of the first coil and the second coil are configured to pass through the threading holes; the two ends of the first coil are movably connected to form a first adjustable portion, a third end of the second coil is continuously connected to a first end of the first coil to form a fixing portion, the fixing portion is configured to compress a fourth end of the second coil to form a second adjustable portion. By providing the first adjustable portion and the elastic portion, not only the purpose of automatically adjusting the length of the coil in the loop is achieved, but also the coil in the loop cannot be enlarged and retreated due to the pulling force of a graft when no artificial external force exists, the operation time is shortened, and the operation risk is reduced. A manufacturing method of the loop is further provided by the present invention.

An orthopedic attachment system includes a first bone anchor, a second bone anchor, and a flexible connector. The flexible connector is connected between the first bone anchor and the second bone anchor. The flexible connector includes a sliding loop, a tensioning end and a fixed end. The sliding loop is connected to a sling loop bone anchor, and the fixed end is connected to the fixed end bone anchor. The tensioning end is slidably connected and lockable to the fixed end. A flexible connector, a method for attaching a flexible connector between at least two bone anchors in a patient's body, and a method of making a flexible connector are also disclosed.

An anchor for attaching injured soft tissue to a bone and generating a therapeutic electromagnetic field at least in a part of the soft tissue when the soft tissue is sutured to the anchor, the anchor comprising: a) an affixing portion configured for affixing the anchor to the bone; b) a coil that generates the electromagnetic field when a current runs through it; c) an electronics module that controls the current in the coil; and d) an electric power source that provides electric power to the electronics module and the coil.

The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.
