| 20080243261 | MOBILE BEARING ASSEMBLY HAVING A CLOSED TRACK - A mobile tibial assembly includes a tibial tray and a tibial insert. The tibial tray includes a closed track. The tibial insert includes a stem configured to be inserted into the closed track and retained therein. The tibial insert is movable along the closed track once inserted. | 10-02-2008 |
| 20090088754 | Customized Patient-Specific Multi-Cutting Blocks - A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed. | 04-02-2009 |
| 20090088763 | Customized Patient-Specific Bone Cutting Block with External Reference - A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed. | 04-02-2009 |
| 20090326665 | POSTERIOR STABILIZED ORTHOPAEDIC KNEE PROSTHESIS HAVING CONTROLLED CONDYLAR CURVATURE - An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature of the condyle surface may be increased during mid-flexion. | 12-31-2009 |
| 20090326666 | POSTERIOR STABILIZED ORTHOPAEDIC PROSTHESIS - A posterior stabilized knee orthopaedic prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The tibial bearing includes a spine having a concave cam surface and a convex cam surface. The femoral component includes a posterior cam having a concave cam surface and a convex cam surface. During flexion, the concave cam surface of the posterior cam contacts the convex cam surface of the spine and the convex cam surface of the posterior cam contacts the concave cam surface of the spine. | 12-31-2009 |
| 20100016978 | ANTERO-POSTERIOR PLACEMENT OF AXIS OF ROTATION FOR A ROTATING PLATFORM - A knee replacement system includes a femoral component including a lateral condylar articulating portion and a medial condylar articulating portion, a tibial tray including an upper articulating surface, and a tibial insert including (i) a first articulating portion for articulating with the lateral condylar articulating portion with a first condylar dwell point, (ii) a second articulating portion for articulating with the medial condylar articulating portion with a second condylar dwell point, (iii) a lower articulating surface for articulating with the upper articulating surface, and (iv) a coupling member for coupling with the tibial tray and defining an axis of rotation about which the tibial insert rotates with respect to the tibial tray, the axis of rotation intersecting the upper articulating surface at a location posterior to a dwell axis including the condylar dwell points when the dwell axis is projected onto the upper articulating surface. | 01-21-2010 |
| 20100016979 | KNEE PROSTHESES WITH ENHANCED KINEMATICS - A knee replacement system includes a proximal tibial posterior camming portion defined by a first radius of curvature with a first origin in a first medio-lateral plane, a distal tibial posterior camming portion defined by a second radius of curvature with a second origin in a second medio-lateral plane, an anterior femoral camming portion of a posterior cam defined by a third radius of curvature with a third origin in the first medio-lateral plane, and a posterior femoral camming portion of the posterior cam and defined by a fourth radius of curvature with a fourth origin in the second medio-lateral plane, wherein the second origin is closer to the lateral tibial portion than the first origin, or the fourth origin is closer to the medial femoral portion than the third origin. | 01-21-2010 |
| 20100036500 | ORTHOPAEDIC KNEE PROSTHESIS HAVING CONTROLLED CONDYLAR CURVATURE - An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing. | 02-11-2010 |
