Abstract
A total knee prosthesis system that includes a guide having first and second wedges each having a thickness configured to be located between the tibial and femoral component. When the first and second wedges are located between the tibial and femoral component, the first and second wedges align the first axle opening of the tibial component with the second axle opening of the femoral component for receipt of an axle. The guide includes a guide recess extending between the first and second wedges and a post extending into the guide recess. The guide also includes a bridge connected to and extending between the first and second wedges such that the bridge at least partially defines the guide recess.
Claims15
A total knee prosthesis system, comprising:
- an axle;
- a tibial component having a baseplate portion, an articular portion connected to the baseplate portion, and a protruding portion extending from the baseplate and articular portions, the protruding portion having a first axle opening for receipt of the axle;
- a femoral component having a distal surface and a second axle opening for receipt of the axle;
- and
- a guide having first and second wedges each having a thickness configured to be located between the tibial component and the femoral component such that, when the first and second wedges are located between the tibial component and the femoral component, the first and second wedges align the first axle opening with the second axle opening for receipt of the axle therein.
A total knee prosthesis system, comprising:
- a femoral component having first and second condylar portions each defining a convex distal surface, the first and second condylar portions further defining an intercondylar recess therebetween and a first axle opening extending therethrough, the axle opening being in communication with the intercondylar recess;
- a tibial component defining a concave proximal surface;
- an axle;
- a coupling component coupled to the tibial component and having a head portion extending from the tibial component, the head portion defining a second axle opening;
- and
- a wedge shaped assembly guide having an upper surface, a lower surface, and a thickness therebetween,
- wherein, when the head portion is received within the intercondylar recess and the wedge shaped assembly guide is interposed between the tibial component and femoral component, the thickness of the assembly guide positions the femoral component such that the first axle opening coaxially aligns with the second axle opening, and
- wherein the axle is configured to be inserted into the coaxially aligned first and second axle openings.
