Patent ID: 8313530

Claim:
A system for performing a total knee replacement surgery comprising: a cutting member; a single jig configured to guide the cutting member in cutting a distal portion of a femur to form a prepared distal surface, the prepared distal surface having a prepared shape; a first femoral component having a first proximal side; a second femoral component having a second proximal side; the first proximal side and the second proximal side being substantially similar and configured to engage the prepared shape; the first femoral component having a first distal side; the second femoral component having a second distal side; wherein the first distal side is shaped differently than the second distal side; a first tibial component having a first inner surface shaped to receive the first distal side of the first femoral component but not the second distal side of the second femoral component: a second tibial component having a second inner surface shaped to receive the second distal side of the second femoral component but not the first distal side of the first femoral component; wherein the first femoral component and the second femoral component are configured to be used with either a left femur or a right femur; wherein the first tibial component and the second tibial component are configured to be used with either a left tibia or a right tibia; wherein the first femoral component and the first tibial component are configured to engage each other in a first high flexion knee prosthesis able to achieve a flexion angle of greater than 120 degrees; and wherein the second femoral component and the second tibial component are configured to engage each other in a second high flexion knee prosthesis able to achieve a flexion angle of greater than 120 degrees.
