Summary: | The present invention comprises a polymeric based femoral and/or tibial component implant to be used in total knee replacement/arthroplasty procedures serving to provide increased wear resistance, enhanced physiological response at the bone/implant interface, and decreased stress-shielding. The implant can be made via additive manufacturing. The articulating surface of the implant may be implemented in without any additive or in a form containing an additive for improved tribological response. Further, the device disclosed herein contains an interfacial surface which is in contact with the native bone (i.e., bone/implant interface) which may exist in its pure form, containing a bioactive additive. The implant has a porous morphology on the bone/implant interface for improved biological response and improved fixation. The depth of the additives and the topographical morphology therein are controlled via techniques disclosed herein. |
