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.

A method of assembling a hinge knee prosthesis, comprising:
- coupling an alignment member with a tibial component having a first axle opening;
- positioning a head portion of a coupling component extending from the tibial component into an intercondylar recess of a femoral component having a second axle opening;
- engaging the femoral component with the alignment member such that the first axle opening aligns with the second axle opening;
- inserting an axle into the first and second axle openings so as to hingedly connect the femoral component with the coupling component;
- and
- after inserting the axle, removing the alignment member from the tibial component.
A method of assembling a hinge knee prosthesis, comprising:
- positioning an alignment member between a tibial component and a femoral component, wherein the alignment member is configured to position the femoral component relative to a head portion of a coupling component extending from the tibial component such that a first axle opening of the femoral component aligns with a second axle opening of the coupling component;
- positioning the head portion of the coupling component into an intercondylar recess of the femoral component;
- inserting an axle into the first and second axle openings so as to hingedly connect the femoral component with the coupling component;
- and
- after inserting the axle, removing the alignment member from between the tibial component and the femoral component.
