Publication number: 20150320545Abstract: Methods for fixation of a soft tissue graft in a bone including: forming in the bone a tunnel defining an entrance opening and an exit opening at opposite ends of the tunnel, the tunnel including an anterior wall surface and a posterior wall surface opposite to the anterior wall surface; positioning the soft tissue graft within the tunnel such that the soft tissue graft extends through both the entrance opening and the exit opening of the tunnel; inserting a graft fixation apparatus into the tunnel and driving spikes of the graft fixation apparatus into the posterior wall surface to mount the graft fixation apparatus to the posterior wall surface of the tunnel such that the graft fixation apparatus is anterior to the posterior wall surface and is not recessed beneath the posterior wall surface; and securing the soft tissue graft inside the tunnel with the graft fixation apparatus.Type: ApplicationFiled: April 17, 2015Publication date: November 12, 2015Inventors: James BOUCHER, Stephen M.

Patent number: 8647385Abstract: An apparatus and method for fixation of a soft tissue graft. The apparatus may include a member having a first surface and a second surface. Each of the surfaces extend a distance relative to one another. A member is operable to resist movement of the apparatus relative to an anatomical portion. An interference member may be provided to fixedly associate the apparatus with the anatomical structure.Type: GrantFiled: July 16, 2012Date of Patent: February 11, 2014Assignee: Biomet Sports Medicine, LLCInventors: James Boucher, Stephen M.

Publication number: 20050143830Abstract: A prosthetic patellar component includes a base and a bearing element that includes first and second femoral engaging surfaces disposed between first and second (superior/inferior) edge surfaces. The edge surfaces are curved to provide a gradual transition from a posterior facing portion to a nearly vertical superior or inferior facing portion. Moreover, the inferior-superior dimension of the component is at least approximately 90% of the medial-lateral dimension. The relative height and gradually transitioning edges significantly reduce the likelihood of sudden posterior rotation during deep flexion movement. The edge surfaces extend from a substantially posterior facing portion proximate to the first and second femoral engaging surfaces and a substantially vertical facing portion proximate the base.Type: ApplicationFiled: February 23, 2005Publication date: June 30, 2005Inventors: James Marcinek, Mark Lester, Alan Marchant

Patent number: 6755840Abstract: An apparatus and method for tibial fixation of a soft tissue graft includes a body having a first side and a second side. A first plurality of spikes extend from the second side of the body each having a first length. A second plurality of spikes extend from the second side of the body each having a second length where the first length is longer than the second length. The first plurality of spikes are operable to engage the bone without the second plurality of spikes substantially engaging the soft tissue graft to permit proper tensioning of the soft tissue graft. The method includes forming a tunnel in a bone and forming a counterbore substantially perpendicular with the tunnel. The soft tissue graft passes through the tunnel and the counterbore and is secured within the counterbore with an apparatus which is nested within the counterbore.Type: GrantFiled: June 10, 2002Date of Patent: June 29, 2004Assignee: Arthrotek, Inc.Inventors: James A. Boucher, Stephen M. Howell, James Marcinek, Troy M. Walters

The first plurality of spikes are operable to engage the bone without the second plurality of spikes substantially engaging the soft tissue graft to permit proper tensioning of the soft tissue graft. The method includes forming a tunnel in a bone and forming a counterbore substantially perpendicular with the tunnel and partially within an entrance opening of the tunnel.
