| 20100292705 | Sizing Guide for Femoral Prosthesis - A posterior-referencing apparatus for sizing the resected distal femur prior to implanting the femoral component of a total knee prosthesis. The apparatus can be used for sizing either the left or right femur. The apparatus has a first operable orientation adapted for sizing the left femur and a second operable orientation offset 180 degrees from the first operable position for sizing the right femur. The apparatus can be reconfigured between left and right orientations quickly and easily without disassembling the apparatus. | 11-18-2010 |
| 20100057088 | Distal Femoral Cutting Guide - An apparatus for resecting the distal face of either the left or right femur at a predetermined valgus angle relative to the patient's intramedullary canal prior to implanting the femoral component of a total knee prosthesis. The apparatus has a distal elongate sword having a longitudinal axis and being adapted for insertion into the intramedullary canal of the femur. A proximal handle is connected to and has a longitudinal axis coaxial with the sword. A base cartridge is fixed intermediate the sword and handle and has an axial passage extending therethrough. A face plate is fixed at the distal end of the base cartridge and is adapted to abut the face of the natural distal femur. The face plate is oriented at the predetermined valgus angle relative to the longitudinal axis of the sword. A cutting jig connects to the base cartridge. The cutting jig has a guide plate with at least one blade slot adapted to receive and guide a cutting blade, and a bracket that supports the guide plate and detachably engages the axial passage and orients the at least one blade slot at the predetermined valgus angle relative to the longitudinal axis. | 03-04-2010 |
| 20090319049 | Total Knee Replacement Prosthesis With High Order NURBS Surfaces - A knee replacement prosthesis comprising a femoral component and a tibial component that enable anterior-posterior translation of the femur relative to the tibia and enable the tibia to rotate about its longitudinal axis during flexion of the knee. The femoral component connects to the distal end of a resected femur and includes medial and lateral condyles having distal, articulating surfaces, and a patellar flange having a patellar articulating surface. The tibial component connects to the proximal end of a resected tibia and includes a proximal bearing surface with medial and lateral concavities that articulate with the medial and lateral condyles. The condylar articulating surfaces and the said concavities are substantially defined by non-uniform, rational B-spline surfaces (NURBS). | 12-24-2009 |

The femoral component connects to the distal end of a resected femur and includes medial and lateral condyles having distal, articulating surfaces, and a patellar flange having a patellar articulating surface. The tibial component connects to the proximal end of a resected tibia and includes a proximal bearing surface with medial and lateral concavities that articulate with the medial and lateral condyles. The articulating surfaces of the condyles and concavities are defined by sections of toroids. | 12-24-2009 |
