1. A prosthetic knee system, comprising:
- a femoral knee prosthesis formed of two separate components, a lateral condyle and a medial condyle, wherein the lateral and medial condyles are assembled in-vivo;
a tibial knee insert formed of two separate components, a lateral insert adapted to articulate with the lateral condyle and a medial insert adapted to articulate with the medial condyle; and
a tibial baseplate formed of two separate components, a lateral baseplate component and a medial baseplate component, wherein the lateral insert connects to the lateral baseplate component, the medial insert connects to the medial baseplate component, and the lateral baseplate component connects in-vivo to the medial baseplate component.

Abstract
A modular prosthetic knee system used to replace the natural knee. The system includes a femoral knee prosthesis and a tibial knee prosthesis. Both prostheses are formed of modular components that are connectable in-vivo to form the prosthetic knee system. The femoral knee prosthesis includes two separate components, a lateral condyle and medial condyle; and the tibial knee prosthesis includes a multiple separate components, a medial baseplate, a lateral baseplate, a medial insert, and a lateral insert. The medial and lateral baseplate are connectable to form a complete baseplate with the medial and lateral inserts connectable to the complete baseplate.

16. A modular prosthetic knee system implantable in a knee using minimally invasive surgery, the prosthetic knee system comprising:
-
a femoral knee prosthesis formed of a lateral condyle and a medial condyle, wherein the lateral and medial condyles are separate components that are connected together in-vivo; and
a tibial knee prosthesis having two separate components including a lateral insert and baseplate and a medial insert and baseplate, the tibial knee prosthesis having an articulation surface for articulating with the lateral and medial condyles of the femoral knee prosthesis, wherein lateral insert and baseplate are inserted through a lateral incision in the knee and the medial insert and baseplate are inserted through a medial incision in the knee, the lateral insert and baseplate being connectable in-vivo to the medial insert and baseplate. - View Dependent Claims (17, 18, 19, 20)
