| 20090084491 | Cementless Tibial Tray - The present teachings provide a tibial tray and a method for making the same. According to one example, a substrate having a superior surface can be formed. Porous metal material can be attached onto the superior surface of the substrate. Selected areas of the substrate can be removed to form first features of the tibial tray. Selected areas of the polymer portion can be removed to form second features of the tibial tray. | 04-02-2009 |
| 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 |
| 20100305698 | Knee Prosthesis Assembly With Ligament Link - A prosthetic knee joint assembly includes a femoral component that engages a femur and at least one bearing that supports articulation of the femoral component thereon. Also, the assembly includes a tibial tray that engages a tibia and that supports the bearing. A ligament link coupling component is included on the femoral component or the tibial tray. The ligament link coupling component is operable to couple to a ligament link to couple the ligament link to the femoral component or the tibial tray. Moreover, the assembly includes an opening included on the other of the femoral component or the tibial tray. The ligament link is received in the opening to bypass the other of the femoral component or the tibial tray to operably couple to the respective one of the femur or the tibia. | 12-02-2010 |
| 20100305709 | Knee Prosthesis Assembly With Ligament Link - A prosthetic knee joint assembly includes a femoral component and a bearing that supports articulation of the femoral component. The assembly further includes a tibial tray. Furthermore, the assembly includes a ligament link operably coupled to the tibial tray or the femoral component via a coupling component. The ligament link extending through the other of the tibial tray or the femoral component to couple to the respective one of the femur or tibia. The ligament link extends between first and second ends and includes an outer wall defining an interior longitudinal passage portion. First and second apertures extend through the wall. The first end extends through the first and second apertures and the longitudinal passage portion to define a first adjustable loop, and the second end extends through the first and second apertures and the longitudinal passage portion to define a second adjustable loop. | 12-02-2010 |
| 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 |
| 20110046735 | Patient-Specific Implants - An endoprosthetic device includes a monolithic meniscal implant having a three-dimensional patient-specific tibial engagement surface nesting in and complementary to a proximal surface of the proximal tibia of a patient and a femoral articulating surface opposite to the tibial engagement surface for articulating with a femoral condyle of the patient. The meniscal implant includes a first portion and a second remainder portion, wherein the first portion is compressible relative to the second remainder portion. | 02-24-2011 |
| 20110092804 | Patient-Specific Pre-Operative Planning - A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint. | 04-21-2011 |
| 20110202139 | PROSTHETIC DEVICE WITH DAMPER - A prosthetic joint assembly supports articulation of a joint. The joint assembly includes a first component configured to be fixed to an anatomical feature. The first component includes a first impact surface and a second component that engages the first component. The second component includes a second impact surface that impacts the first impact surface as the first component moves relative to the second component. Furthermore, at least one of the first impact surface and the second impact surface includes a dampening member that dampens energy resulting from impact of the first and second impact surfaces. | 08-18-2011 |
