Biocompatibility and Mechanical Properties. Currently, their are no suitable artificial materials for the prosthetic replacement of articular cartilage. The biocompatibility is considered the primary criterion in the selection of such a material. In a recent study, Furst and co-workers(10) compared the biocompatibility of the polyurethane to the well known medical grade silicone polymer. The tissue reactions to small polymer discs, inserted in an articulating space—the suprapatellar bursa of rabbits, was examined. The foreign body reaction of the tissue at the implantation site was evaluated at intervals of 7 days,... 

Conclusions. Results from the biocompatibility studies in rabbit supratellar bursa, measurement of hydrophilic properties, lubrication and wear in-vitro studies, determination of viscoelastic properties, measurement of damping coefficient and impact test, total elbow joint replacement design and in-vivo percutaneous implant experiment, all indicate that this series of polyurethanes is an excellent candidate biomaterial for the prosthetic replacement of articular cartilage, artificial joint prostheses and percutaneous implantable devices. 

We must first ask if it is desirable to attempt to replace all these losses with like-for-like components. If so, we need to strive to make a bionic limb of similar weight embodying anthropomorphic articulations with equally powerful motors and distributed sensors connected back into the wearer s residual neuromuscular system. Or, is it better to accept the losses and redefine the optimal functioning of the new unit of person-plus-technology In many cases, it may be concluded that a wheelchair is the optimal solution for lower limb loss. Even if engineering could provide the bionic solution, which it certainly cannot at present despite huge inroads made into aspects of these demands, there remain additional problems inherent to prosthetic replacements to consider. Of these, the unnatural mechanical interface...
