Publication number: 20120116407Abstract: The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing a minimally invasive knee surgery in which a smaller than normal incision is made and oriented to preserve the quadriceps mechanism and protect the suprapatellar pouch. The instruments permit switching from a minimally invasive technique to a standard open technique at any point in the procedure. An illustrative set of instruments for total knee arthroplasty and an associated minimally invasive technique are described.Type: ApplicationFiled: January 12, 2012Publication date: May 10, 2012Applicant: ZIMMER, INC.Inventors: Thomas M. Coon, E. Marlowe Goble, Alfred J. Tria, JR., Warren Scott Gareiss, Robert A. Hodorek, Toby N. Farling, Daniel F. Justin, Donald M. Smucker, Richard R. Van Zile

Patent number: 7344540Abstract: A method and apparatus for resectioning a patella without everting it includes a resection guide which grips the patella with gripping members, one of which can also function as an alignment guide for a surgeon using a saw for the resectioning. A sizing/alignment guide engageable with the resection guide is provided for aligning drills and/or reamers used in resectioning. Under one embodiment, a pair of reamers are provided for reaming the patella in two reaming operations.Type: GrantFiled: February 25, 2003Date of Patent: March 18, 2008Assignee: Zimmer, Inc.Inventors: Donald M.

Patent number: 7338497Abstract: A femoral impactor-extractor and method includes a body having an elongated passageway extending from a proximal end to a distal end, an elongated post positioned in such passageway for longitudinal movement therein and extending from a threaded proximal end to a distal end having an enlarged flange with a greater length than breadth. The proximal end of the elongated post is threaded and threadedly engaged to a rotatable handle. Rotation of the handle moves the elongated post and its flange in a proximal direction to clamp the femoral knee prosthesis between the ends of the flange and contoured surfaces which engage the articulating surfaces of the respective condylar portions of the prosthesis.Type: GrantFiled: December 5, 2003Date of Patent: March 4, 2008Assignee: MIS-TKA Group, LLCInventors: Thoms M. Coon, Alfred J. Tria, Jr., Donald M. Smucker

Patent number: 6770077Abstract: A femoral knee saw guide for use in surgery includes a cutting guide having a slot extending therethrough for guiding a saw and alignment structure attached to the guide and positioned externally of the patient's femur for effecting proper alignment of the cutting guide. The cutting guide may be used for cutting one or both condyles at the distal end of the femur in a medial to lateral direction or lateral to medial direction. An arm having a stylus extending into the plane defined by the path of travel of the saw may be used when it is desired to cut only a single condyle to prevent inadvertently cutting the opposing condyle.Type: GrantFiled: October 9, 2001Date of Patent: August 3, 2004Assignee: NEMCO Medical, Ltd.Inventors: Richard R.
