Abstract

A knee prosthesis (10, 20) is disclosed. In one example of an embodiment, a knee prosthesis includes a load bearing member (12, 22) and a stem (14, 24) arranged and configured to couple within an intramedullary canal of a bone of a patient. In some embodiments, the knee prosthesis may also include a coupler (16) for coupling the handle to the load bearing component. In use, the stem is offset and angled relative to the load bearing member so as to facilitate receipt of the stem in an arcuate or angled intramedullary canal of a patient's tibia or femur. In one example of an embodiment, the coupler may include a first end (32) and a second end (34), a central longitudinal axis (33) of the first end and a central longitudinal axis (35) of the second end being offset from each other, not parallel to each other, and not intersecting at any point or intersecting a path of each other.
