The elbow prosthesis may additionally include a condyle extending from the joint and including an axis of rotation that is eccentric from the first axis. ## Claims ### Claim 1 An elbow prosthesis comprising: a first stem component for attachment to one of a humerus and an ulna; a second stem component for attachment to the other of the humerus and the ulna; a joint disposed between and coupling said first stem component and said second stem component to permit relative movement between said first stem component and said second stem component about a first axis; and a condyle extending from said joint, said condyle rotatably coupled to said joint for rotation about an axis of rotation that is eccentric from said first axis. ### Claim 2 (depends on 1) The elbow prosthesis of claim 1, wherein said condyle includes a first condyle component and a second condyle component. ### Claim 3 (depends on 2) The elbow prosthesis of claim 2, wherein said first condyle component is rotatably attached to said second condyle component. ### Claim 4 (depends on 2) The elbow prosthesis of claim 2, wherein said first condyle component includes an axis of rotation that is eccentric from said first axis and said second condyle component includes an axis of rotation that is substantially concentric with said first axis. ### Claim 5 (depends on 2) The elbow prosthesis of claim 2, wherein one of said first condyle component and said second condyle component includes a projection and the other of said first condyle component and said second condyle component includes a recess operable to rotatably receive said projection. ### Claim 6 (depends on 5) The elbow prosthesis of claim 5, wherein at least one of said projection and said recess includes a taper, said taper permitting relative rotation between said first condyle component and said second condyle component in a first state and restricting relative rotation between said first condyle component and said second condyle component in a second state. ### Claim 7 (depends on 5) The elbow prosthesis of claim 5, wherein said projection and said recess each include an axis of rotation that is offset from said first axis. ### Claim 8 (depends on 5) The elbow prosthesis of claim 5, wherein said projection and said recess each include an axis of rotation that is offset from a central axis of said first condyle component and that is offset from a central axis of said second condyle component. ### Claim 9 (depends on 2) The elbow prosthesis of claim 2, further comprising an intermediate condyle component disposed between said first condyle component and said second condyle component. ### Claim 10 (depends on 9) The elbow prosthesis of claim 9, wherein said intermediate component includes a first projection that is rotatably attached to said first condyle component and is offset from a central axis of said intermediate component and a second projection that is rotatably attached to said second condyle component and is offset from said central axis of said intermediate component. ### Claim 11 (depends on 10) The elbow prosthesis of claim 10, wherein said first projection and said second projection are offset from one another. ### Claim 12 (depends on 1) The elbow prosthesis of claim 1, wherein said axis of rotation is substantially parallel to said first axis. ### Claim 13 An elbow prosthesis comprising: a first stem component for attachment to one of a humerus and an ulna; a second stem component for attachment to the other of the humerus and the ulna; a joint disposed between and coupling said first stem component and said second stem component to permit relative movement between said first stem component and said second stem component about a first axis; and a first condyle component rotatable with one of said first stem component and said second stem component about said first axis; and a second condyle component rotatable relative to said first condyle component about a second axis, such that said second condyle component is configured to be coupled to the first condyle component in first and second orientations, the first orientation offset from the second orientation by an angle of rotation about the second axis. ### Claim 14 (depends on 13) The elbow prosthesis of claim 13, wherein said second axis is eccentric from said first axis. ### Claim 15 (depends on 13) The elbow prosthesis of claim 13, wherein said second axis is offset from said first axis. ### Claim 16 (depends on 13) The elbow prosthesis of claim 13, wherein said second axis is different than said first axis. ### Claim 17 (depends on 13) The elbow prosthesis of claim 13, wherein one of said first condyle component and said second condyle component includes a projection and the other of said first condyle component and said second condyle component includes a recess operable to rotatably receive said projection. ### Claim 18 (depends on 17) The elbow prosthesis of claim 17, wherein at least one of said projection and said recess includes a taper, said taper permitting relative rotation between said first condyle component and said second condyle component in a first state and restricting relative rotation between said first condyle component and said second condyle component in a second state. ### Claim 19 (depends on 17) The elbow prosthesis of claim 17, wherein said projection and said recess each include an axis of rotation that is offset from said first axis. ### Claim 20 (depends on 17) The elbow prosthesis of claim 17, wherein said projection and said recess each include an axis of rotation that is offset from a central axis of said first condyle component and that is offset from a central axis of said second condyle component. ### Claim 21 (depends on 13) The elbow prosthesis of claim 13, further comprising an intermediate condyle component disposed between said first condyle component and said second condyle component. ### Claim 22 (depends on 21) The elbow prosthesis of claim 21, wherein said intermediate component includes a first projection that is rotatably attached to said first condyle component and is offset from a central axis of said intermediate component and a second projection that is rotatably attached to said second condyle component and is offset from said central axis of said intermediate component. ### Claim 23 (depends on 22) The elbow prosthesis of claim 22, wherein said first projection and said second projection are offset from one another. ### Claim 24 (depends on 13) The elbow prosthesis of claim 13, wherein said second condyle component is rotatably coupled to said first condyle component for rotation about said second axis.
