Patent ID: 8366782

Claim:
A modular orthopaedic knee implant system comprising: a distal femoral component having a distal articulating surface and a proximal side; a proximal tibial component having a proximal surface and distal side; an adapter having a proximal end and a distal end, wherein the distal end is sized and shaped to be capable of being connected to the proximal side of the distal femoral component; and a stem extension having a connecting end, a body and an opposite end, the connecting end having external threads; wherein the connecting end of the stem extension is sized and shaped to be capable of being selectively connected directly to the proximal tibial component and directly to the adapter; and wherein the adapter includes: a distal interior surface defining a distal bore at the distal end of the adapter, the distal bore having a central longitudinal axis; and a proximal interior surface defining a proximal bore at the proximal end of the adapter, the proximal bore having a central longitudinal axis defining an acute angle with the central longitudinal axis of the distal bore when viewed in a plane extending in a medial-lateral direction; wherein the proximal interior surface of the proximal bore is threaded.
