The fixing screw includes a shaft part having a self-tap portion and a male screw portion, a head part, and a lumen. The fixing screw can be screwed into the bone plug in a state where a guide pin pierced into the bone plug penetrates the lumen of the fixing screw and a pulling member mounted to the bone plug and extended from the bone tunnel is being pulled. The fixing screw can adjust a tensile force of the tendon graft by adjusting the amount of screwing of the fixing screw into the bone plug after the head part of the fixing screw contacts the fixing member.Type: GrantFiled: May 22, 2009Date of Patent: March 20, 2012Assignee: Meira CorporationInventor: Konsei Shino

Patent number: 8137383Abstract: A method for securing first and second tissues with a suture anchor. The steps include forming a borehole in the first tissue; threading a suture through the second tissue forming a loop in the suture with the tissue thereby secured in the loop, the loop defining two suture portions; attaching the two suture portions to the anchor whereby the two suture portions are threaded through the anchor and initially movable with respect to the anchor; and providing a force to a shaft of the anchor, the force causing clamping of the two suture portions in the anchor and deformation of a deformable portion of the anchor to cause the deformable portion to engage a wall of the borehole thereby to secure the suture anchor in the first tissue and the loop holding the second tissue to the suture anchor.Type: GrantFiled: October 27, 2010Date of Patent: March 20, 2012Assignee: Linvatec CorporationInventors: Hugh Sloan West, Jr., Lehmann K.

Publication number: 20120065732Abstract: An adjustable, knotless button/loop/needle construct for fixation of cranial cruciate ligament deficient stifle. The adjustable, knotless construct includes two fixation devices (for example, two buttons), at least one flexible, adjustable loop attached to at least one of the fixation devices (e.g., the buttons), and two needles (each needle being attached to one fixation device, e.g., the buttons). The adjustable, knotless construct has an adjustable loop length and allows adjustment in one direction while preventing or locking the construct from loosening in the opposite direction, due to applied tensile forces. The construct and technique of the present invention provides an improved knotless system for cruciate ligament repair.Type: ApplicationFiled: November 17, 2011Publication date: March 15, 2012Inventors: Brandon L. Roller, Eric S. Zajac, Ricardo Albertorio

Publication number: 20120065731Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.Type: ApplicationFiled: September 23, 2011Publication date: March 15, 2012Applicant: MEDICINELODGE, INC.

Publication number: 20120059469Abstract: A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.Type: ApplicationFiled: August 30, 2011Publication date: March 8, 2012Applicants: MEDICINELODGE, INC.

Publication number: 20120059468Abstract: A strap for repairing the attachment between a bone and a soft tissue according to embodiments of the present invention includes an elongated flexible textile body including, along its longitudinal direction, first and second longitudinal parts, the first longitudinal part including a fixation mechanism, the fixation mechanism configured to mechanically cooperate with the second longitudinal part, after the second longitudinal part has been passed through at least the soft tissue, to form a loop around at least a portion of the soft tissue, wherein the fixation mechanism permits tightening of the loop to tension the elongated flexible textile body to hold the soft tissue in place with respect to the bone.Type: ApplicationFiled: March 2, 2011Publication date: March 8, 2012Inventors: Ralph MATTERN, Jamal RUSHDY, Dale PETERSON, Kevin OHASHI, Justin C.
