A modular knee prosthesis includes a femoral stem having a proximal end portion. A femoral component includes a first engagement portion defined thereon wherein the femoral stem is selectively attachable to the first engagement portion of the femoral component. A connecting member includes a first end selectively attachable to the first engagement portion of the femoral component and includes a second engagement portion defined on a second end wherein the femoral stem is selectively attachable to the second engagement portion of the connecting member.
What is claimed is: 1. A modular knee prosthesis comprising: a femoral stem having a proximal end portion defining a first tapered male insertion portion; a femoral component having a first tapered female receiving portion defined thereon; an adapter body including a first end defining a second tap
What is claimed is: 1. A modular knee prosthesis comprising: a femoral stem having a proximal end portion defining a first tapered male insertion portion; a femoral component having a first tapered female receiving portion defined thereon; an adapter body including a first end defining a second tapered male insertion portion and a second end defining a second tapered female receiving portion, the adapter body connecting said femoral stem and said femoral component and establishing a relative offset between said femoral stem and said first tapered female receiving portion, wherein said first tapered male insertion portion cooperatively mates with said second tapered female receiving portion, and wherein said first tapered female receiving portion cooperatively mates with said second tapered male insertion portion, said adapter body further including a sidewall defining an opening; and a locking arrangement for coupling said femoral stem to said adapter body, said locking arrangement including a locking element passing through said opening and coupling said femoral stem to said adapter body. 2. The modular knee prosthesis of claim 1 wherein said locking element further couples said femoral stem to said femoral component. 3. The modular knee prosthesis of claim 2 wherein said locking element threadably receives a fastener extending through said femoral component. 4. The modular knee prosthesis of claim 2 wherein said second male tapered insertion portion defines a first axis, and said second female tapered receiving portion defines second axis, said first and second axes being parallel to one another and spaced apart. 5. The modular knee prosthesis of claim 1 wherein said first male tapered insertion portion defines a first Morse taper connection with said second female tapered receiving portion and wherein said second male tapered insertion portion defines a second Morse taper connection with said first female tapered receiving portion. 6. The modular knee prosthesis of claim 1, further comprising a stem insert extending from said proximal end portion of said stem and wherein said locking element engages said stem insert. 7. The modular knee prosthesis of claim 6 wherein said stem insert is threadably received by said proximal end portion of said stem. 8. A modular knee prosthesis comprising: a femoral stem having a proximal end portion defining a first tapered male insertion portion; a femoral component having a first tapered female receiving portion defined thereon; an adapter body including a first end defining a second tapered male insertion portion and a second end defining a second tapered female receiving portion, said second tapered male insertion portion defining a first axis and said second tapered female receiving portion defining a second axis, said first and second axes being parallel to one another and spaced apart, wherein said first tapered male insertion portion cooperatively mates with said second tapered female receiving portion, and wherein said first tapered female receiving portion cooperatively mates with said second tapered male insertion portion, thereby establishing a relative offset between said first tapered male insertion portion and said first tapered female receiving portion, said adapter body further including a sidewall defining an opening; and a locking arrangement that couples said femoral stem to said femoral component, said locking arrangement including a locking element that passes through said opening and receives a first fastener extending from said femoral component and a second fastener extending from said stem thereby coupling said femoral stem to said femoral component. 9. The modular knee prosthesis of claim 8 wherein said first fastener is a threaded screw that threadably engages said locking element to tighten said femoral stem and said femoral component to said adapter body.
