| 20090254367 | Method and Apparatus for Manufacturing an Implant - An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant. | 10-08-2009 |
| 20090299482 | Knee Joint Prosthesis System and Method for Implantation - A prosthesis for replacing a knee joint between a femur and a tibia can include a femoral component having a first condylar portion, a second condylar portion, a first sidewall and a second sidewall that collectively comprise a first hinge portion. A tibial component can have a first engagement portion formed thereon. A bearing can have an articulating inferior surface adapted to articulate along the bearing. The bearing can have an opening. A yoke can have an inferior portion and superior portion, the superior portion having an axle that comprises a second hinge portion. The inferior portion can have a second engagement portion and be configured to at least partially pass through the opening. The femoral component is operable to rotate relative to the tibial component about a superior/inferior axis a first rotational distance until the first and second engagement portions engage each other and inhibit further rotation. | 12-03-2009 |
| 20100087829 | Patient Specific Alignment Guide With Cutting Surface and Laser Indicator - A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient. The patient-specific guiding system includes a patient-specific guide. The guide includes a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface. The first portion also includes a guide surface for use in guiding the instrument relative to the anatomical feature. The guide also includes a second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface. The second portion is removably connected to the first portion. | 04-08-2010 |
| 20100174378 | Knee Joint Prosthesis System and Method for Implantation - A prosthesis system for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing, a first yoke, and a first key. The femoral component can include a first condylar portion, a second condylar portion, a first sidewall extending superiorly from the first condylar portion, a second sidewall extending superiorly from the second condylar portion where the first and second sidewalls collectively comprise a first hinge portion. The tibial component can have a bone engaging inferior surface and a bearing engaging superior surface. The bearing can have an inferior that engages the bearing engaging surface and a superior femoral engaging surface. The bearing can define an opening. The first yoke can have an inferior portion, a superior portion and a yoke keyway extending through the therethrough. | 07-08-2010 |
| 20100217109 | Mechanical Axis Alignment Using MRI Imaging - A method of imaging a body part of a patient can include acquiring a first, second and third sets of image data from a first, second and third anatomical reference areas. The first, second and third sets of image data can then be compiled to produce a legend of the body part. The legend can have positional information of the first, second and third anatomical reference areas. A fourth, fifth and sixth sets of image data of the first, second and anatomical reference areas can be acquired. The fourth, fifth and sixth sets of image data can have increased image information relative to the first, second and third sets of image data, respectively. The locations of the fourth, fifth and sixth sets of image data relative to the first, second and third sets of image data can be correlated using the legend to determine a characteristic of the body part. | 08-26-2010 |
| 20100312351 | Knee Prosthesis With Rotatable Post - A knee joint prosthesis for implantation to replace a portion of a knee joint. The knee joint prosthesis includes a tibial tray and a bearing member that engages the tibial tray. The prosthesis also includes an insert with a base that is fixed to the bearing member and an extension portion that extends away from the bearing member and the tibial tray. The extension portion has an axis, and the extension portion includes a threaded portion. The prosthesis further includes a post that is rotatably coupled to the extension portion, and the post is rotatable about the axis of the extension portion relative to the insert. Furthermore, the prosthesis includes a retention member that threadably couples to the threaded portion of the insert to limit movement of the post along the axis away from the bearing member and the tibial tray. | 12-09-2010 |
| 20100324692 | Method and Apparatus for Manufacturing an Implant - An orthopedic device includes a femoral implant having a non-custom internal bone engagement surface. The femoral implant includes at least nine parameters adjusted preoperatively to correspond to a specific patient. The parameters can include patient-specific lengths, such as, for example, medial and lateral condyle widths and notch height, and patient-specific medial and lateral angles. | 12-23-2010 |
