Patent number: 8808298Abstract: The present disclosure provides a cut guide for use in preparation of the distal femur to form the anterior, anterior chamfer, distal, posterior chamfer and posterior facets as well as the intercondylar box cuts utilized to prepare a femoral intercondylar box. To allow for the use of a single cutting guide to make all of these femoral osteotomies, the present disclosure implements an orthopedic guide assembly including a primary guide body with a secondary guide body rotatably connected to the primary guide body. With this configuration, the secondary guide body can be rotated into an operable position to guide a femoral osteotomy and may also be rotated into an inoperable position in which it is moved from a configuration (i.e., the operable position) in which it acts as a barrier to movement of an osteotome across a guide surface of the primary guide body.Type: GrantFiled: May 18, 2012Date of Patent: August 19, 2014Assignee: Zimmer, Inc.Inventors: Kevin M.

Patent number: 8795282Abstract: A surgical instrument and method determine the orientation of the mechanical axis of a femur. The instrument may include a rod with a first end of the rod rotatably secured at a first point on the surface of distal femur that corresponds to center of the knee joint so that the first end is coincident with the mechanical axis. The connection between the first end of the rod and the distal end of the femur defines a first point of rotation. The second end of the rod is slideably received within a sleeve that is rotatably connected to a support positioned distally away from the distal end of the femur. The connection between the sleeve and the support defines a second point of rotation. When the distance between the first and second points of rotation is minimized, a line drawn therebetween is coincident with the mechanical axis of the femur.Type: GrantFiled: January 28, 2010Date of Patent: August 5, 2014Assignee: Zimmer, Inc.Inventors: Brian D.
