Publication number: 20180008292Abstract: A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.Type: ApplicationFiled: September 22, 2017Publication date: January 11, 2018Inventors: Robert Metzger, Keith R.

Publication number: 20170367848Abstract: Systems, devices, and methods are provided for measuring forces in the space of a knee during surgery. Such forces can be caused by tension in the ligaments of the knee. A femoral member is engaged with a distal femur. While the knee is flexed, partially extended, or fully extended, a force sensor and a gauge shim can be placed in the gap between the femoral member and the tibial plateau to measure the forces therebetween. The force sensor provides an accurate and quantifiable measurement of force, making knee replacement surgery and ligament tension balancing more accurate, standardized and repeatable. The force sensor comprises an elongate housing which comprises a thin force sensing distal portion and a proximal handle portion.Type: ApplicationFiled: July 12, 2017Publication date: December 28, 2017Inventors: Michael G. Fisher, Andrew P. Sizelove, Keith R. Berend, David Wycliffe Murray

Publication number: 20170042685Abstract: An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complementary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.Type: ApplicationFiled: October 31, 2016Publication date: February 16, 2017Inventors: Aaron P. Smith, Tyler D. Witt, Hugh Apthorp, Keith R. Berend, Andrew Freiberg, John Barrington, David R. Brown

Patent number: 9498339Abstract: A prosthesis can have a wall portion that deforms to conform to a surface. The deformation of the wall can be plastic (i.e. permanent) or elastic (i.e. able to return to the pre-deformed configuration). The surface can be an anatomical surface.Type: GrantFiled: November 5, 2013Date of Patent: November 22, 2016Assignee: Biomet Manufacturing, LLCInventors: Keith R. Berend, Kirk J. Bailey

Publication number: 20160278868Abstract: A method of preparing a surgical plan comprises video capturing a range of motion of an anatomic joint of a patient to obtain a range of motion video, registering the range of motion video to two-dimensional images of a skeleton of the patient, identifying potential impingement and stability issues in the anatomic joint based on the range of motion video, templating a prosthetic implant on two-dimensional images of the anatomic joint using the identified potential impingement and stability issues of the anatomic joint to obtain position and orientation data, and electronically saving the position and orientation data of the prosthetic implant for use with a surgical navigation system. A system for planning and performing a surgical procedure comprises a motion capture system, an x-ray system, an electronic modeling system, and a surgical navigation system.Type: ApplicationFiled: March 25, 2016Publication date: September 29, 2016Inventors: Michael E.
