A method of using a suture construct that is engaged and organized onto a card holder. The card holder includes a number of different retention features for maintaining and organizing the suture construct and its respective free ends for ease of use during surgery. The suture construct has an oblong button defining at least a first aperture and a second aperture; a suture assembly, engaged to the button and defining a lumen; and a shuttle assembly, having a loop end in the form of a shuttle loop, and a free end, and passing through the lumen between the loop end and the free end. In the method, the suture assembly is engaged to the tendon graft and the shuttle is used to pull a portion of the suture assembly through the lumen. Finally, the suture construct is disengaged from the card holder.

A system for harvesting a tendon graft is disclosed, the system including a retractor, a guide and at least one harvesting tool. The retractor holds open an anatomic space in a patient above the tendon. The guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. A first harvesting tool and the guide include a plurality of surfaces that cooperate with each other to transect the tendon and form at least one side of the tendon graft, the plurality of surfaces cooperating to limit a trajectory and a depth of cut into the tendon and also limiting both ends of the translational extent of the harvesting tool along the tendon. A second harvesting tool may extend along the anatomic space formed by the retractor and form both a posterior cut along the tendon and transect a tendon graft end.

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.

The invention relates to the technical field of transplanted tendon weaving, in particular to an anterior cruciate ligament reconstruction and collection transplanted tendon weaving device which comprises a first weaving table and a second weaving table and further comprises a first connecting frame and a second connecting frame, and the first connecting frame and the second connecting frame are fixedly connected to the upper surfaces of the first weaving table and the second weaving table in a clamped mode respectively. And a connecting hinge is connected between the first connecting frame and the second connecting frame. A traditional integrated weaving platform is replaced, the weaving device can be folded and stored when the weaving device is idle, the occupied space of the weaving device is reduced, the weaving device is convenient to carry and carry, a plurality of small ligaments can be woven into anterior cruciate ligaments of the needed length specification at different height positions, good applicability is achieved, and the weaving device is suitable for popularization and application. The tension adjusting device is simple in structure, high in flexibility and convenient to operate, tension adjustment can be conducted on the woven ligament under the condition that the woven ligament is not damaged, the stability of the tension adjusting process is improved, and the safety of the woven ligament is guaranteed.

The present invention relates to a composition for inducing ligamentization of tendons, comprising anterior cruciate ligament-derived stem cells. The use of the composition can inhibit fibrosis in tendon grafts used for anterior cruciate ligament reconstruction surgeries and promote the healing process. Additionally, the composition may further include extracellular matrix proteins of the cruciate ligament tissue.

A method of constructing a button, suture, and tendon graft combination, utilizing a tendon graft, a holder and a construct engaged to the holder. The construct has an oblong button defining at least a first aperture and a second aperture; a suture assembly, engaged to the button and defining a lumen; and a shuttle assembly, having a loop end in the form of a shuttle loop, and a free end, and passing through the lumen between the loop end and the free end. In the method, the suture assembly is engaged to the tendon graft and the shuttle is used to pull a portion of the suture assembly through the lumen. Finally, the construct is disengaged from the holder.

The utility model discloses a round closed tendon taking device, which belongs to the technical field of medical instruments and equipment, and comprises a round tendon taking device which is used for taking autologous quadriceps femoris tendon as a cylindrical ligament graft in a knee joint cruciate ligament reconstruction operation, and the round tendon taking device comprises an operating handle, a connecting rod and a tendon taking head, the tendon taking head is formed by sleeving a tendon graft with a cutting part, the head end of the tendon taking head is obliquely sharp, and a tendon taking hole is formed in the head end of the tendon taking head; the device is specially designed for conveniently cutting and cutting a cylindrical cruciate ligament transplantation plant from an autologous quadriceps femoris tendon, in the taking-out process, a medical worker holds the operating handle by hand to sleeve the tendon taking hole in the head end of the tendon taking head at the head end of the tendon taking head, and the tendon is cut and separated through the inclined sharp head end of the tendon taking head, so that the medical worker can take out the tendon conveniently and quickly. The whole taking-out process is convenient and labor-saving to operate, the edge of the taken-out graft is flat and not coarse, the size of the graft can be accurately determined according to different requirements, and the graft taking-out device is simple in structure and convenient to widely use.
