An orthopedic prosthesis for implantation into a bone of a patient, said orthopedic prosthesis comprising: a porous metal shell adapted to be affixed within the bone, said porous metal shell having an outer bone engaging surface adapted to receive bone ingrowth after the implantation and an inner bearing engaging surface adapted to directly engage a bearing liner, wherein said porous metal shell is porous from said outer bone engaging surface to said inner bearing engaging surface characterized in that said porous metal shell defines a first annular pocket formed about an inner radius thereon and a second collar that projects radially inwardly therefrom; wherein the orthopedic prosthesis is further characterized in that the orthopedic prosthesis further comprises a non-porous member comprising a non-porous rim defined at a radial edge of said porous metal shell, said non-porous rim defining a second annular pocket formed about an outer radius thereon and a first collar that projects radially outwardly therefrom, wherein each of said first and second collars (102, 106) nest within each of said first and second annular pockets (96, 98) respectively, said non-porous rim further comprising at least one pair of raised walls extending from a planar surface defined on an outer face of said non-porous rim, wherein each raised wall of said at least one pair of raised walls defines an attachment feature formed at least in part by a tapered wall surface adapted to mate with a complementary structure provided on an implantation tool (130, 250, 300, 400). a porous metal shell adapted to be affixed within the bone, said porous metal shell having an outer bone engaging surface adapted to receive bone ingrowth after the implantation and an inner bearing engaging surface adapted to directly engage a bearing liner, wherein said porous metal shell is porous from said outer bone engaging surface to said inner bearing engaging surface characterized in that said porous metal shell defines a first annular pocket formed about an inner radius thereon and a second collar that projects radially inwardly therefrom; wherein the orthopedic prosthesis is further characterized in that the orthopedic prosthesis further comprises a non-porous member comprising a non-porous rim defined at a radial edge of said porous metal shell, said non-porous rim defining a second annular pocket formed about an outer radius thereon and a first collar that projects radially outwardly therefrom, wherein each of said first and second collars (102, 106) nest within each of said first and second annular pockets (96, 98) respectively, said non-porous rim further comprising at least one pair of raised walls extending from a planar surface defined on an outer face of said non-porous rim, wherein each raised wall of said at least one pair of raised walls defines an attachment feature formed at least in part by a tapered wall surface adapted to mate with a complementary structure provided on an implantation tool (130, 250, 300, 400). a non-porous member comprising a non-porous rim defined at a radial edge of said porous metal shell, said non-porous rim defining a second annular pocket formed about an outer radius thereon and a first collar that projects radially outwardly therefrom, wherein each of said first and second collars (102, 106) nest within each of said first and second annular pockets (96, 98) respectively, said non-porous rim further comprising at least one pair of raised walls extending from a planar surface defined on an outer face of said non-porous rim, wherein each raised wall of said at least one pair of raised walls defines an attachment feature formed at least in part by a tapered wall surface adapted to mate with a complementary structure provided on an implantation tool (130, 250, 300, 400).
